40 N.
Answer:
1.274.
Explanation:
- Thomas Graham found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>∨ ∝ 1/√M.</em>
where, ∨ is the rate of diffusion of the gas.
M is the molar mass of the gas.
<em>∨₁/∨₂ = √(M₂/M₁)</em>
∨₁ is the rate of effusion of the methane.
∨₂ is the rate of effusion of acetylene gas.
M₁ is the molar mass of methane (M₁ = 16.0 g/mol).
M₂ is the molar mass of acetylene (M₂ = 26.0 g/mol).
<em>∴ The rate of effusion of methane, CH₄, relative to the rate of effusion of acetylene, C₂H₂ = ∨₁/∨₂ = √(M₂/M₁) </em>= √(26.0 g/mol)/(16.0 g/mol) = <em>1.274.</em>
Answer: 0.040 mol/l
Explanation: Molarity c = n/V (Concentration)
c = 0.060 mol / 1,5 l = 0,040 mol/l
Answer:
B. The reactants will react to produce more H₂O
Explanation:
Given the reaction
2H₂+O₂→2H₂O
A decrease in the amount of H₂O will cause the reaction to produce more H₂O. When you change something, the reaction seeks to undo that change.
