Explanation:
How many moles of NH3 can be produced from 5.50 moles of nitrogen in the following reaction: N2+3H2=2NH3
Answer:
Explanation:
Let the molar balance numbers be your guide.
N2 has a one in front of it.
2 NH3 has a two in front of it.
Nitrogen has 5.50 moles given.
1 / 5.50 = 2 / x Cross multiply
1 x = 2 * 5.50
x = 11.0
So if you use 5.5 moles of nitrogen, you get 11 moles of NH3

When the concentration of SO2(g) is increased to 1.48 M, the ratio of products to reactants is 1.4. The equilibrium constant for the reaction is 14. In which direction will the reaction shift to regain equilibrium
Answer:
Towards the products
Explanation:
The equilibrium constant for the reaction is 14. The equilibrium will shift towards the product.
What is equilibrium?Equilibrium is defined as a condition in which the forward and backward reaction rates are identical. When all of the external forces acting on an object are balanced, the object is said to be in equilibrium in a reference coordinate system. This indicates that all external forces and moments acting on this item have a net effect of zero.
When sulfur dioxide SO2 concentration is increased, the Q value rises to 1.4.
Q = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]
Q = 1.4
Where K
K = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]
K = 14
Q will shift to the right to consume the extra SO2 and restore the equilibrium position since Q is less than K.
Thus, the equilibrium constant for the reaction is 14. The equilibrium will shift towards the product.

a peanut butter and jelly sandwich contains 9.00 g of fat, 6.00 g of protein, and 25.0 g of carbohydrate. How many calories does this sandwich provide?
Answer:
205 calories.
Explanation:
According to the USDA, "Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram." 9 grams of fat at 9 calories per equals 81 calories + 6 grams of protein at 4 calories per gram which equals 24 calories + 25 grams of carbohydrate at 4 calories per gram which is equal to 100 calories.
Total that all up and you get 81 cal + 24 cal + 100 cal=205 calories.
I don't know what kind of course this is for, but if they are incredibly picky, what we refer to as "calories" are actually kilocalories, which are equal to one thousand "real" calories each. However, I'm very confident that the correct answer is 205 calories.
The sandwich will provide 205 calories.
What is calories?A calorie is an energy unit. It's the quantity of heat needed to increase the temperature of one gramme of water by [tex]1^{0} C[/tex] at one atmosphere of pressure.
Its is given that, Fat = 9 g, protein = 6 g, carbohydrate = 25 g.
It is known that, fat contains 9 calories / gram , carbohydrate contains 4 calories / gram and protein contains 4 calories / gram.
Now, adding all terms.
Total calories = (9×9) +(6×4) +(25×4)
= 205 calories.
Therefore, the sandwich will provide a total of 205 calories.

Recreational drug users often obtain the drug as a white powder with unknown purity. Some users snort the power, whereas others make a solution and take it orally or inject it. To achieve a ketamine high, users usually need to take between 0.1 mg/kg and 1 mg/kg of ketamine. However, taking 2 mg/kg can lead the user to experience a K-hole or to enter an unconscious state.
If the user dissolves exactly 1 g of ketamine in 1/4 cup of water, what is the concentration of ketamine in milligrams per milliliter (mg/mL)? 1 cup=236.5 mL
What volume, in milliliters, of the recreational ketamine in the previous question would a 59.0 kg user need to take to experience a high at 0.600 mg/kg?
How many milliliters would that same user need to take to become unconscious at 2.00 mg/kg?
A user dissolves exactly 1 g of ketamine in 1/4 cup of water.
Given 1 cup = 236.5 mL, the volume of 1/4 cup of water is:
1/4 cup × (236.5 mL/1 cup) = 59.13 mL
1 g of ketamine is dissolved in 59.13 mL of water. The concentration of ketamine, in mg/mL, is:
C = 1000 mg / 59.13 mL = 16.91 mg/mL
Part 2The volume of this solution that a 59.0 kg user (body mass) would have to consume to experience a high at 0.600 mg/Kg is:
[tex]59.0 kgBM \times \frac{0.600mgKetamine}{1kgBM} \times \frac{1mL Soluiton}{16.91mgKetamine} = 2.09 mL[/tex]
Part 3The volume of this solution that a 59.0 kg user (body mass) would have to consume to become unconscious at 2.00 mg/kg is:
[tex]59.0 kgBM \times \frac{2.00mgKetamine}{1kgBM} \times \frac{1mL Soluiton}{16.91mgKetamine} = 6.98 mL[/tex]
If a user dissolves exactly 1 g of ketamine in 1/4 cup of water, the resulting concentration is 16.91 mg/mL. A 59.0 kg user would have to consume 2.09 mL of this solution to experience a high of 0.600 mg/kg. The same user would have to consume 6.98 mL of this solution to become unconscious at 2.00 mg/kg.Learn more about concentration units here: https://brainly.com/question/14594475

The protons are positively charged particles and neutrons are neutral particles and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged particles and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not change the chemical properties of the substances.

Answer: 4
Explanation:
An unknown hydrocarbon compound was analyzed for hydrogen by elemental analysis and results show that it contains 15.88 % H. What is the empirical formula
Answer:
C4H9
Explanation:
If H = 15.88%
Then C = 100.00 – 15.88 = 84.12
Divide each % value by respective atomic mass
H = 15.88/1 = 15.88
C = 84.12/12 = 7.01
Divide through by smaller value
H = 15.88/7.01 = 2.26
C = 7.01/7.01 = 1
Remove fraction , multiply by 4
H = 9
C = 4
Empirical formula = C4H9
The hydrocarbon could be ( C4H9)2 = C8H18 = octane.

1. A closed bottle contains a mixture of Ar and O2 at 25.3°C. If the partial pressure of Ar in
the bottle is 0.447 atm and the total pressure of the bottle is 1.024 atm, what is the partial
pressure of O2 in the bottle?
Answer: 0.79 atm
Explanation:
The Ideal Gas Law is PV=nRT.
since both Ar and O2 have the same volume and temperature, the only variable causing the differnce in pressure betwwen the 2 gases is the number of moles
the total pressure = the partial pressure of Ar + the partial pressure of O2
1.024 atm = 0.447 amt + ?
so
? = 1.24 -0,447 = 1.24 - 0.45= 0.79 atmthe total pressure of the bottle is 1.024 atm, what is the partial
pressure of O2 in the bottle? is PV

How many moles of O₂ would be required to generate 13.0 mol of NO₂ in the reaction below assuming the reaction has only 80.0% yield?
Answer:
Chemical reaction:
2 NO (g) + O₂ (g) → 2 NO₂ (g)2 moles of NO₂ is produced from O₂ moles = 1
Therefore, 2 moles of NO₂ is produced from O₂ moles = [tex]\dfrac{1}{2} \times 13 = \bf{6.5 mol}[/tex]
For 80 % yield no. of moles of O₂ = 6.5 mol

Suppose you are performing a titration. At the beginning of the titration, you read the titrant volume as 2.51 mL. After running the titration and reaching the endpoint, you read the titrant volume as 29.95 mL. What volume, in mL, of titrant was required for the titration
The volume of titrant required for the titration would be 27.44 mL
From the illustration, the initial titrant volume was 2.51 mL. This figure represents the initial reading on the burette.
In the same vein, the final volume of the titrant was 29.95 mL. This figure represents the final reading on the burette.
In order to get the volume of titrant used:
Volume of titrant used = final volume - initial volume
= 29.95 - 2.51
= 27.44 mL
