how does the formula change when writing alcohols???
Answers
Answer:
An alcohol has a C-O-H bond.
Explanation:
The formula for an alkane contains only C and H atoms, e.g., CH₃-CH₂-H.
If you have an alcohol, the formula changes by having an O atom between a C and an H, e.g., CH₃-CH₂-O-H.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s

A student predicts that a solution of ethanol (C2H5OH) and water will have a lower density at room temperature than that of pure water. By taking moisture the student can test this prediction.
What are the properties of ethanol ?Ethanol is a natural plant fermented by-product which can also be produced by the process of hydration of ethylene.
It is an important industrial reagent, can be used as a solvent, for the synthesis of solvent, organic chemicals and some additive to automotive gasoline.
Its chemical formula is C2H6O, two carbon atoms and one oxygen atom where as the structural formula is C2H5OH indicating that the two-carbon chain has a hydroxyl group.
Ethanol is always a liquid at room temperature and has the melting point of 156K and a boiling point of 351 K.
It is used in making many medicines like cough syrups, tonics, any proportion of ethanol is soluble in water.
Direct consumption of even a small quantity of pure ethanol is lethal to body.

In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.
Answers
Answer:The answer is C: How long does it take distilled water to evaporate from a 5” diameter container?
Explanation:
In the air, a salt solution will evaporate more slowly than pure water.
What is Evaporation?
The process by which a liquid transforms into a gas state is called evaporation. A surface phenomena, that is. The amount of evaporation depends on the humidity. If the air is humid, it is virtually saturated, which means that evaporation will occur at a much slower rate.
Since evaporation takes place on the liquid's surface, the salt molecules that are present on the water's surface prevent as much water from evaporating. As a result, salt water evaporates more slowly than pure water.
As a result, the salt solution will evaporate from the air more slowly than pure water.

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.

Answer:spectrum
Explanation:
Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.
So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.
But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.
So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Answers
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.
