Answer:
0.84 mol
Explanation:
Given data:
Moles of ZnCl₂ produced = ?
Mass of Zn = 55.0 g
Solution:
Chemical equation:
2HCl + Zn → ZnCl₂ + H₂
Number of moles of Zn:
Number of moles = mass / molar mass
Number of moles = 55.0 g/ 65.38 g/mol
Number of moles = 0.84 mol
Now we will compare the moles of Zn with ZnCl₂ from balance chemical equation.
Zn : ZnCl₂
1 : 1
0.84 : 0.84
So from 55 g of Zn 0.84 moles of zinc chloride will be produced.
Explanation:
Reaction equation:
CO + 2H₂ → CH₃OH
All the species are in gaseous state and the equation is balanced.
Change in pressure only affects equilibrium involving a gas or gases.
Based on Le Chatelier's principle, an increase in pressure will shift the position of equilibrium to the side having smaller volume or number of moles and vice versa.
CO + 2H₂ → CH₃OH
3moles of gases 1 mole of gas
An increase in pressure favors the forward reaction. A decrease in pressure will favor the backward step.
