How many moles of HCL would be required to produce a total of 2 moles of H2? A)0.5 B)2 C)3 D)15

1 answer:

4 0

To determine the number of moles of HCl from 2 moles of H2, we take stoichiometry to solve this problem. The balanced equation is 2HCl= H2+Cl2 Using stoichiometry, the expression becomes 2 mole H2*(2 molHCl/1 mole H2). The answer is 4 moles.

If the pressure of 125 cm3 of nitrogen gas at 100 °c decreases from 885 torr to 225torr, what is the final volume? assume temper

navik [9.2K]

Suppose the Gas is acting ideally, Then, According to Ideal Gas Equation;

P₁ V₁ = P₂ V₂ ----- (1)
Data Given:
P₁ = 885 torr

V₁ = 125 cm³

P₂ = 225 torr

V₂ = ?

Puting values in eq, 1;

V₂ = P₁ V₁ / P₂

V₂ = (885 torr × 125 cm³) ÷ 225 torr

V₂ = 491.66 cm³
