Answer:
Explanation:
according to balance chemical equation
3 A2 moles produced 2 moles of A3B
so 12 moles A2 will produced moles of A3B= 12*2/3=24/3= 8
therefore 12 moles of A2 produced 8 moles of A3B
A balanced chemical reaction is an equation that has the same number of stoichiometry coefficients on both sides. When 12 moles of A₂ react, then 8 moles of A₃B are produced.
Excess reagents are the reactants that are present in more quantity than the other reactant and are left in reaction after completion.
The balanced chemical equation:
3A₂ + B₂ → 2A₃B
From reaction: 3 moles of A₂ molecule are needed to produce 2 moles of A₃B. So, 12 moles of A₂ will produce:
(12 × 2) ÷ 3 = 8 moles
Therefore, 8 moles of A₃B will be produced from 12 moles of A₂.
