Hi!
Basically, you will want to cross product your 20 moles of HCl with the number of moles in your H2 (so 1), with that and the number of moles in the HCl (2), you will find that 10 moles of H2 will form from 20 moles of HCl
Answer:
I'm not sure please list the elements respond with the list and I will give the answer.
Answer is: 15.30 kilojoules of heat are needed to completely vaporize C₄H₁₀<span>.
m(</span>C₄H₁₀) = 42.8 g.
M(C₄H₁₀) = 74.12 g/mol.
n(C₄H₁₀) = m(C₄H₁₀) ÷ M(C₄H₁₀).
n(C₄H₁₀) = 42.8 g ÷ 74.12 g/mol.
n(C₄H₁₀) = 0.577 mol.
Q = n(C₄H₁₀) · ΔHvap.
<span>Q = 0.577 mol </span>· 26.5 kJ/mol.
<span>Q = 15.30 kJ, heat of butane.
