The question is incomplete, the complete question is;
An unknown compound has the following chemical formula:
N2Ox
where x stands for a whole number.
Measurements also show that a certain sample of the unknown compound contains 3.7 mol of oxygen and 2.45 mol of nitrogen.
Write the complete chemical formula for the unknown compound.
Answer:
The complete formula of the compound is N2O3.
Explanation:
Given;
Number of moles of N = 2.45 moles
Number of moles of O = 3.7 moles
Chemical formula of unknown compound = N2Ox
From the ratio of the number of moles of N to O;
2/x = 2.45/3.7
2 * 3.7 = x * 2.45
x = 2 * 3.7/ 2.45
x =3
Hence the complete formula of the compound is N2O3.
Answer:
A. As pressure decreases, the concentration of gas molecules in the solution increases.
D. The solubility of nitrogen gas at 2.00 atm is twice the solubility of the gas at 1.00 atm.
F. More gas molecules are soluble as pressure is increased.
The solubility is 188.3 mg of N2 gas/100 g water.
Explanation:
As the pressure on the gas decreases, the volume of gas molecules in the solution increases due to having distance from each other. The solubility of nitrogen gas at 2.00 atm is twice the solubility of the gas at 1.00 atm because there is more pressure on the gas molecules so due to more compression, the gas becomes more soluble. More gas molecules are soluble as pressure is increased. The solubility is 188.3 mg of N2 gas/100 g water if the atmospheric pressure is increases from 3.08 atm to 8.00 atm. This value is calculated with the help of formula i.e. P2/P1 = S2/S1.
