The moles of nitric acid formed can be computed using the stoichiometric relation obtained from the given equation which indicates that for every 3 moles of nitrogen dioxide (NO2), 2 moles of nitric acid (HNO3) is formed. 300 moles of NO2 is then multiplied to 2 mol HNO3/ 3 mol NO2. The answer is 200 moles of nitric acid is produced from 300 moles of NO2.

Answer;

200.00 moles of nitric acid is produced

Explanation;

From the equation;

3NO2 + H2O → 2HNO3 + NO

The mole ratio of nitrogen (IV) oxide  and nitric acid is 3 is to 2;

Thus; for every 3 moles of nitrogen dioxide (NO2), 2 moles of nitric acid (HNO3) are formed. 

Therefore; 300 moles of NO2 will produce;

2 mol HNO3/ 3 mol NO2 (300) = 200 moles

Hence, 200 moles of nitric acid are produced from 300 moles of NO2.

How many grams of oxygen are produced when 1.05 moles of hydrogen gas is<br> produced?
vivado [14]

Answer:

1.058337 grams of hydrogen and 2H2 + O2 ==> 2H2O hydrogen peroxide

mols H2 = grams/molar mass

Using the coefficients in the balanced equation, convert mols H2 to mols O2.

Now convert mols O2 to grams. That's grams mols O2 x molar mass O2.

and it could also produce H2O water but no air but it could make other things

180m/173 Tl -&gt; 180/173 Tl + ? Express your answer as a nuclear equation ​
Law Incorporation [45]

Answer: The nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.

Explanation:

A nuclear reaction in which a heavy particle splits into another particle along with release of energy is called a nuclear fission reaction.

For example, ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma

Here, energy is radiated in the form of gamma radiation.

Thus, we can conclude that the nuclear equation is ^{180}_{173}Tl \rightarrow ^{180}_{173}Tl + ^{0}_{0}\gamma.

What is the specific heat of a substance if 6527 J are required to raise the temperature of a 312 g sample by 15 degrees Celsius
Tanzania [10]

Answer:

1.395J/g°C

Explanation:

The following were obtained from the question:

Q = 6527J

M = 312g

ΔT = 15°C

C =?

Q = MCΔT

C = Q/MΔT

C = 6527/(312 x 15)

C = 1.395J/g°C

The specific heat capacity of the substance is 1.395J/g°C

A sample of gas initially has a volume of 2.25 L at 350 K and a pressure of 1.75 atm. What will be sample pressure if the volume
IRINA_888 [86]

Answer:

8.44 atm

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 2.25 L

Initial temperature (T₁) = 350 K

Initial pressure (P₁) = 1.75 atm

Final volume (V₂) = 1 L

Final temperature (T₂) = 750 K

Final pressure (P₂) =?

The final pressure of the gas can be obtained as illustrated below:

P₁V₁/T₁ = P₂V₂/T₂

1.75 × 2.25 / 350 = P₂ × 1 / 750

3.9375 / 350 = P₂ / 750

Cross multiply

350 × P₂ = 3.9375 × 750

350 × P₂ = 2953.125

Divide both side by 350

P₂ = 2953.125 / 350

P₂ = 8.44 atm

Thus, the final pressure of the gas is 8.44 atm.
