Answer: Number of atoms in 
of radon gas (radon atoms) at the same temperature and pressure is 
Explanation:
According to avogadro's law, volume of a gas is directly proportional to the number of moles present when temperature and pressure is constant.:
= moles of hydrogen gas = 
= moles of radon gas = ?
Thus the number of atoms in of radon gas (radon atoms) at the same temperature and pressure is
Not completely sure but I’d say salt comes from small ocean orgasisms
Tissues. Hope it helps (let me know if it was correct)
Answer:
62L
Explanation:
2 H2(g) + O2(g) → 2 H2O(g)
From the stoichiometry of the balanced equation;
2 mol of H2 reacts with 1 mol of O2.
From the law of combining volumes, equal moles of gases occupies equal volume.
This means;
2 L of H2 reacts with 1 L of O2
x L of hydrogen reacts with 31 L of O2
2 = 1
x = 31
Solving for x;
x = 62 L
Answer:
The answer to your question is: yield = 30.9%
Explanation:
Data
mass of compound isolated = 25 g
theoretical mass = 81 g
Formula
% yield = mass of compound isolated / theoretical mass x 100
% yield = 25 / 81 x 100
% yield = 30.9
