Answers
Explanation:
First, let's rewrite the equation here:
4 NH3 + 6 NO -> 5 N2 + 6 H2O.
The equation tells us that 6 moles of NO produces 5 moles of N2.
But the question wants us to find the quantity in grams of NO required if we have 121 g of N2.
1. So first, let's transform 121 g of N2 into moles, using its molar mass (28 g/mol) and the following formula: moles = mass/molar mass
2. Then, we use the equation ratio between NO and N2: 6:5.
3. Then we transform the result into grams of NO, using its molar mass (30.01 g/mol) and the following formula: mass = moles*molar mass
1. moles = 121/28
moles = 4.3 moles of N2
2. 6 moles of NO --- 5 moles of N2
x moles of NO --- 4.3 moles of N2
5x = 4.3*6
x = 25.9/5
x = 5.2 moles of NO
3. mass = 5.2*30.01
mass = 155.6 g
Answer: It will require 155.6 g of NO.

Using the following reaction, determine the theoretical yield of Acetylsalicylic acid if given 2.31 grams of salicylic acid? (reminder, salicylic acid is the limiting reagent)
Answers
The theoretical yield of Acetylsalicylic acid is found out to be: 3.01 grams.
What is limiting reagent?The limiting reagent is a substance that prevents a chemical reaction from occurring completely.
When a limiting reagent is used in a chemical reaction, the atoms, molecules, or ions of the other reactant that it (the limiting reagent) reacts with will either stay free or unreacted.
What is acid?Popular compounds called acids and bases interact with one another to create salt and water. The Latin word "acere," which meaning "sour," is where the term "acid" originates.
According to the problem, we have 2.31 grams of salicylic acid. We need to determine the theoretical yield of acetylsalicylic acid.
The molar mass of salicylic acid is 138.12 g/mol. Therefore, the number of moles of salicylic acid we have is:
n = mass / molar mass
n = 2.31 g / 138.12 g/mol
n = 0.0167 mol
According to the balanced equation, 1 mole of salicylic acid reacts with 1 mole of acetic anhydride to produce 1 mole of acetylsalicylic acid. Therefore, the number of moles of acetylsalicylic acid produced is also 0.0167 mol.
The molar mass of acetylsalicylic acid is 180.16 g/mol. Therefore, the theoretical yield of acetylsalicylic acid is:
mass = n x molar mass
mass = 0.0167 mol x 180.16 g/mol
mass = 3.01 g
Therefore, the theoretical yield of acetylsalicylic acid is 3.01 grams.

What mass of oxygen is needed for the complete combustion of 1.60-10^-3
g
of methane?
Express your answer with the appropriate units.
Answers
Answer:
6.4×10¯³ g of O₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the masses of CH₄ and O₂ that reacted from the balanced equation. This can be obtained as follow:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4
= 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of O₂ = 2 × 16 = 32 g/mol
Mass of O₂ from the balanced equation = 2 × 32 = 64 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted with 64 g of O₂.
Finally, we shall determine the mass of O₂ needed to react with 1.6×10¯³ g of CH₄. This can be obtained as illustrated below:
From the balanced equation above,
16 g of CH₄ reacted with 64 g of O₂.
Therefore, 1.6×10¯³ g of CH₄ will react with = (1.6×10¯³ × 64) / 16 = 6.4×10¯³ g of O₂
Thus, 6.4×10¯³ g of O₂ is needed for the reaction.

Step 1: Given data
Initial concentration of N₂O₄: 0.0500 M
Equilibrium constant (Kc): 0.513
Step 2: Make an ICE chart
N₂O₄(g) ⇌ 2 NO₂(g)
I 0.0500 0
C -x +2x

1. Commercials for foods that will make you bigger, stronger, and faster seem to appear a lot these days. Research what the ingredients are in a Powerbar. Will this one food source make you stronger? Why or why not?
2. Amino acids are chiral molecules, which means they have two enantiomers (non-superimposable mirror images - like your hands!). Albuterol is a drug where one enantiomer is more effective than a mixture of the two enantiomers. Ritalin is also a drug where one enantiomer is more effective. Why is this in terms of how human bodies can metabolize these drugs individually?
Answers
1. Powerbars are energy bars that contain a variety of ingredients such as protein, carbohydrates, and fats. They are designed to provide a quick source of energy and nutrients for athletes and people who are physically active. While Powerbars can be a good source of nutrients for athletes, they are not a magic food that will make you stronger on their own. Strength and muscle growth are the result of a combination of factors, including regular exercise, proper nutrition, and rest. The protein in Powerbars comes from a variety of sources such as soy, whey, and casein. Protein is important for building and repairing muscle tissue, but consuming more protein than your body needs will not necessarily make you stronger. In fact, consuming excessive amounts of protein can be harmful to your health. Overall, while Powerbars can be a convenient source of energy and nutrients for athletes, they are not a substitute for a well-balanced diet and proper exercise routine.
2. Chirality refers to the property of a molecule that has a non-superimposable mirror image. This means that two molecules that are mirror images of each other cannot be overlaid onto each other. Amino acids are chiral molecules, meaning that they have two enantiomers that are non-superimposable mirror images of each other. The human body is able to metabolize the two enantiomers of a drug differently because the enzymes that break down and process the drug are also chiral. Enzymes are specific in their shape and can only bind to one enantiomer of a drug, which means that the other enantiomer is not metabolized as efficiently or may not be metabolized at all. This can result in differences in the effectiveness and side effects of the drug depending on which enantiomer is present. In the case of Albuterol, the R-enantiomer is more effective than the S-enantiomer, and a drug containing only the R-enantiomer has been developed for use in treating asthma. In the case of Ritalin, the S-enantiomer is more effective than the R-enantiomer, and a drug containing only the S-enantiomer has been developed for use in treating attention-deficit/hyperactivity disorder (ADHD). Overall, the chirality of molecules can have important implications for drug development and use, as well as for understanding the mechanisms of drug action and metabolism in the body.
Answer:
1) PowerBars are a sort of energy bar developed to give athletes and fitness enthusiasts with a quick and handy source of nourishment. PowerBar components vary depending on the product, but often include a combination of carbs, protein, and fat, as well as numerous vitamins and minerals.
carbs are the body's major source of energy during activity, and PowerBars often include a combination of basic and complex carbs to offer both fast and long-lasting energy. Protein is also necessary for muscle repair and development, and PowerBars typically provide 10-20 grammes of protein per bar.
while PowerBars can be a handy source of nutrition for athletes and may aid in muscle building and recovery when eaten as part of a well-balanced diet, they are not a quick fix for becoming stronger or faster. Strength and performance may be improved by engaging in regular exercise and following a well-rounded eating plan that includes a range of nutrient-dense meals.
2) Because of variations in how the human body metabolises and reacts to each enantiomer, one enantiomer of a medicine may be more effective than the other. Enantiomers contain the same chemical formula and functional groups as one another, but their 3D structures are mirror reflections of one another, resulting in distinct interactions with biological molecules such as enzymes, receptors, and transporters.
In the instance of albuterol, the R-enantiomer is more effective than the S-enantiomer because it has a stronger affinity for the drug's target, the beta-2 adrenergic receptor. Because the R-enantiomer is metabolised more slowly by the body, it remains active for a longer amount of time and creates a stronger and longer-lasting impact.
Similarly, the S-enantiomer of Ritalin is more efficacious than the R-enantiomer. The S-enantiomer is more effective in blocking dopamine and norepinephrine reuptake, which are neurotransmitters involved in attention and focus. The R-enantiomer has less effect on these neurotransmitters and is metabolised quickly by the body, resulting in a shorter duration of action.
In summary, changes in pharmacological efficacy across enantiomers are caused by differences in their interactions with biological molecules as well as variances in how the body metabolises them. These distinctions can have serious consequences for therapeutic effectiveness and safety.

6.3 × 10–11 M H3O+ and 1.6 × 10–4 M OH–
Answers
Explanation:
To find H3O+, do the following:
pH = -log[H3O+]
-pH = log[H3O+]
antilog -(8.3) = antilog log (antilog and log cancel out) [H3O+]
5.0 x 10^-9 = [H3O+]
To find OH, you need to know pOH
pOH = 14 - pH
pOH = 14 - 8.3
pOH = 5.7
To find OH-, use a similar formula to the one above:
pOH = -log [OH-]
-pOH = log [OH-]
antilog - (5.7) = antilog log (antilog and log cancel out) [OH-]
2.0 x 10^-6 = [OH-]

Hydrogen gas is collected over water at 23°C, 767 torr. At this temperature the vapor pressure of water is 21.0 torr. What is the partial pressure of hydrogen in the collected gas?
Answers
The partial pressure of hydrogen gas in the collected gas is 746 torr.
To determine the partial pressure of hydrogen gas in the collected gas, we need to consider the difference between the total pressure of the collected gas and the vapor pressure of water at the given temperature. The partial pressure of hydrogen gas is the pressure exerted by hydrogen alone.
Given information:
Total pressure of the collected gas (Ptotal) = 767 torr
Vapor pressure of water (Pwater) = 21.0 torr
The partial pressure of hydrogen gas (Phydrogen) can be calculated using Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas.
Phydrogen = Ptotal - Pwater
Plugging in the given values:
Phydrogen = 767 torr - 21.0 torr
Phydrogen = 746 torr
Therefore, the partial pressure of hydrogen gas in the collected gas is 746 torr.
It's important to note that in this calculation, we assume that the water vapor does not react with or dissolve in the hydrogen gas and that the gases behave ideally. Additionally, it's assumed that the collected gas is dry, meaning all the water vapor has been removed or does not significantly contribute to the total pressure.

since we have 75 moles of copper but only 70 moles of chlorine gas, after everything has been reacted we would expect 5 moles of copper to be left over. so, copper is the the reactant which is in excess

Answer:
rate = k ×[H₂] × [I]²
Explanation:
Write the rate law for the following elementary reaction: H₂(g) + 2 I(g) → 2 HI(g) Use k, to stand for the rate constant.
Step 1: Write the elementary reaction
H₂(g) + 2 I(g) → 2 HI(g)
Step 2: Write the rate law
The generic rate law is
rate = k ×[H₂]ᵃ × [I]ᵇ
where,
rate: reaction rate
k: rate constant
[H₂] and [I]: molar concentrations of the reactants
a and b: reaction orders for H₂ and I, respectively
For elementary reactions, the reaction orders coincide with the stoichiometric coefficients. Then, the rate law is:
rate = k ×[H₂] × [I]²
