Sally has touched a hot pan on the stove and burnt her hand. This example shows what type of heat transfer?
Answers
Answer:
Transfer of Heat
You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. Why does it cool down? The heat is transferred from the pan to the surroundings. So you can understand that in both cases, the heat flows from a hotter object to a colder object. In fact, in all cases heat flows from a hotter object to a colder object.

What mass of methanol (Ch3OH) is produced when 86.04 of carbon monoxide reacts with 14.14g of hydrogen
HELPP PLS!?!
Answers
Answer:
98.33 g of CH3OH
Explanation:
Step 1:
The balanced equation for the reaction. This is given below:
CO(g) + 2H2(g) —> CH3OH(l)
Step 2:
Determination of the masses of CO and H2 that reacted and the mass of CH3OH produced from the balanced equation.
This can be obtained as follow:
Molar mass of CO = 12 + 16 = 28 g/mol
Mass of CO from the balanced equation = 1 x 28 = 28 g
Molar mass of H2 = 2x1 = 2 g/mol
Mass of H2 from the balanced equation = 2 x 2 = 4 g
Molar mass of CH3OH = 12 + (3x1) + 16 + 1 = 32 g/mol
Mass of CH3OH from the balanced equation = 1 x 32 = 32 g.
Summary:
From the balanced equation above,
28 g of CO reacted with 4 g of H2 to produce 32 g of CH3OH.
Step 3:
Determination of the limiting reactant.
This can be obtained as follow:
From the balanced equation above,
28 g of CO reacted with 4 g of H2.
Therefore, 86.04 g of CO will react with = (86.04 x 4)/28 = 12.29 g of H2.
From the calculation made above, only 12.29 g out of 14.14 g of H2 given were required to react completely with 86.04 g of CO.
Therefore, CO is the limiting reactant and H2 is the excess reactant.
Step 4:
Determination of the mass of methanol, CH3OH produced from the reaction.
In this case the limiting reactant shall be used because it will give the maximum yield of methanol, CH3OH since all of it were consumed in the reaction.
The limiting reactant is CO and the mass of methanol, CH3OH produced can be obtained as follow:
From the balanced equation above,
28 g of CO reacted to produce 32 g of CH3OH.
Therefore, 86.04 g of CO will react to produce = (86.04 x 32)/28 = 98.33 g
Therefore, 98.33 g of CH3OH were obtained from the reaction.
these days cloths made out of a mixture of synthetic fiber and natural fibers are more popular than those made purly out of synthetic fiber. Discuss the reason for this
Answers
Answer: Clothes purely made of synthetic fibers are not comfortable in a hot and humid environment as they don't have the property to absorb water or sweat quickly so their water-resistant property makes them unsuitable for hot humid environment .
Explanation:
Mixing of synthetic fiber and natural fibers enhances the properties such as strength, elasticity, and ease of ironing and washing. Generally in hot environments it is preferred to wear a mixture of synthetic and natural fiber than wearing only clothes made from synthetic fiber .
Moreover, mixing synthetic fibres with natural fibres enhances their properties, such as strength, elasticity and ease of washing and ironing. Hence, these days clothes made out of a mixture of synthetic fibres and natural fibres are more popular than those made purely out of synthetic fibres.

A. Both are based on hypotheses
B. Both can be used to make predictions
C. Both can be modified if new evidence arises
D. Both are used to explain why a phenomenon happens.
Answers
Answer:
d
Explanation:
Procedure and Data (20 points)
1. Remove the label from a 2- or 3-liter plastic soft drink bottle and wash the bottle. Be sure to rinse it very well so that no soap residue remains. Let the bottle dry.
2. Use a marker to draw a line around the bottle, about one-third of the way up from the bottom.
3. Use scissors to cut along the line you drew on the bottle. To start the cut, poke a hole in the bottle at some point on the line.
4. Place about 2 inches of gravel or pebbles in the bottom of the bottle. This layer will be a place for excess water to collect. It will keep the soil from getting too wet. (Optional: If you want your terrarium to last longer, sprinkle some activated charcoal and moss on top of the gravel or pebbles.)
5. Fill the remaining space in the bottom of the bottle with moist potting soil or dirt. Gently press down on the soil with a gloved hand until the surface of the soil is about 1 inch below the rim.
6. Add plants to the terrarium.
a. If you are using seeds, use your pinkie finger to make 8 to 10 small depressions in the soil. They should be about 0.5 inches deep. Place 1 or 2 seeds in each hole and cover them with soil.
b. If you are using live plants, remove 2 or 3 small plants from their containers. Be sure to keep the root ball intact. Plant them in the soil.
7. Pour tap water onto the soil so that it is moist but not completely soaked. Just a little bit of water should pass through to the pebbles. You should use less than 1 cup of water.
8. Put the bottle back together by sliding the top part onto the bottom part. Keep the top on the outside. You may need to squeeze the rim of the bottom section so the top section will fit around it.
9. Place the cap on the terrarium if it is not on already. Your setup should look like this if you started with young plants:
10. Describe your terrarium, including what you put in it and where those materials came from. Attach a photo or draw a diagram of your terrarium. Add labels to identify the important parts. (8 points)
11. Place your terrarium next to a window where it will receive plenty of natural sunlight. Do not place the terrarium outdoors. Observe the terrarium. If you planted seeds, wait until they sprout to begin recording what you see. If you start with live plants, you can begin recording your observations the next day. Make observations for four days in a row. Look at the terrarium first thing in the morning and at the same time each afternoon. Take note of where water can be observed. Look at how much water is in the pebbles and on the sides at the top of the terrarium. Record your data in the table below. (8 points)
Data Table for Observations in Bright Light

Answers
Is this asking us to do a project for you?
Analysis and Conclusions:
1. Explain how your terrarium modeled each of the following processes in the water cycle. (10 points)
Condensation: In the terrarium, condensation is modeled when water vapor from the soil and plants rises, cools down, and turns into droplets on the inner surface of the bottle.
Evaporation: Evaporation is modeled when water from the soil and plants evaporates and rises as water vapor in the enclosed space of the terrarium.
Precipitation: Precipitation is not directly modeled in the terrarium, as there is no mechanism for rain to fall back into the soil. However, the condensation on the inner surface of the bottle can be seen as a form of "internal precipitation."
Infiltration: Infiltration is not directly modeled in the terrarium, as there is no underground or soil surface for water to infiltrate into.
Transpiration: Transpiration is modeled when water is absorbed by the plant roots, travels through the plant, and then evaporates from the plant's leaves, contributing to the water vapor in the terrarium.
2. Draw a diagram to show how your terrarium modeled the water cycle. Include labels for the five processes in question 1. Add arrows to show how water moves through the water cycle.
(Unfortunately, I cannot see your diagram, so I'm unable to provide specific feedback on it.)
3. How did the force of gravity affect the movement of water in your terrarium? (2 points)
The force of gravity caused water to move downward from the soil to the gravel or pebbles at the bottom of the terrarium. It also caused excess water to collect at the bottom of the terrarium.
4. Compare your observations of the terrarium when it was in bright light and dim light. What can you conclude about how sunlight affected the water cycle in your terrarium? (4 points)
Observations in Bright Light:
- More evaporation and transpiration were observed due to increased sunlight.
- Condensation occurred more prominently on the inner surface of the bottle.
- Water levels in the pebbles were lower due to increased evaporation.
Observations in Dim Light:
- Reduced evaporation and transpiration were observed due to less sunlight.
- Condensation on the inner surface of the bottle might have been less noticeable or slower.
- Water levels in the pebbles remained relatively stable.
Conclusion:
Sunlight plays a significant role in the water cycle within the terrarium. It drives evaporation from the soil and plants, leading to more condensation and a higher water vapor concentration inside the terrarium. In dim light conditions, these processes are slowed down.
5. What is one advantage of using a terrarium to model Earth's water cycle? Explain. (2 points)
One advantage of using a terrarium to model Earth's water cycle is that it provides a contained and observable environment. It allows students to witness and understand various stages of the water cycle, including evaporation, condensation, and transpiration, in a small-scale setting. It can be a visual and hands-on approach to learning about these natural processes.
6. What is one way in which you could improve your terrarium to show more parts of the water cycle? (2 points)
To show more parts of the water cycle, you could create a mechanism for precipitation within the terrarium. For example, you could introduce a small spray bottle and periodically mist the plants inside the terrarium to simulate rain or external precipitation. This would add an additional aspect to the water cycle modeling and demonstrate the effect of precipitation on the enclosed environment.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Max and Jimmy want to jump on a trampoline. Max begins jumping in a steady pattern, making small waves in the trampoline. Jimmy starts jumping on the trampoline too. Suddenly, Max goes twice as high even though he did not put any extra effort into jumping.
What type of wave interaction is this? Explain how it occurred.
Answers
Because there is one wave interfering with the other. They are both separate waves with completely different patterns, and they are running into each other.
Hope this helps! :)
Answer: The wave interaction described in the scenario is known as constructive interference.
Explanation:
Constructive interference occurs when two waves meet and combine in such a way that their amplitudes add up, resulting in a larger wave. In this case, Max's steady pattern of jumping creates small waves on the trampoline, with a certain amplitude.
When Jimmy starts jumping on the trampoline, his waves combine with Max's waves. If the peaks and troughs of both waves align perfectly, they will add up, resulting in a wave with a larger amplitude. This alignment of peaks and troughs leads to constructive interference, causing Max to go twice as high without any additional effort.
The reason behind this phenomenon lies in the nature of waves. When waves meet, their amplitudes can either add up or cancel out, depending on their relative positions. In the case of constructive interference, the peaks of one wave align with the peaks of the other wave, and the troughs align with the troughs, resulting in an increased amplitude. Conversely, in destructive interference, the peaks align with the troughs, leading to a cancellation or reduction in amplitude.
So, in the scenario, Jimmy's waves align with Max's waves in such a way that their amplitudes combine constructively, resulting in Max going twice as high on the trampoline without exerting any extra effort.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

How are forces described?
Answers
Answer:
a force is any interaction that is unchallenged will change the motion of an object you might have heard of the push pull example
Explanation:
The equation to find force is
force = mass * acceleration or F = M * A
Force never creates motion!! although motion can occur
force is measured in the SI unit of newtons
a good example would be kicking a football when the foot ball is kicked your foot is interacting with the ball the ball is the object and your foot is the motion that is pushing on the ball which will then make the ball accelerate in the air so i think to find the force of the ball you take the mass of the object in this case the ball and multiply it by it acceleration or the change in its velocity to get force

The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.
The periodic table is divided using groups (columns) and periods (rows).
Each specific group or period has a specific pattern in the elements.
The modern periodic table is arranged in order of increasing atomic number.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.
