The answer for the question is C
Answer:
The yield is 20 %.
Explanation:
Mg + 2 HCl → MgCl2 + H2
(12 g Mg) / (24.30506 g Mg/mol) x (1 mol H2 / 1 mol Mg) x (2.015894 g H2/mol) = 0.9953 g H2.
(0.2 g) / (0.9953 g) = 0.20 = 20% yield
Answer:
<h2>
2Al +
3CuO ==>
3Cu + Al2O3</h2>
Explanation:
So let's break this chemical equation down into 2 parts - Reactants and Products
Reactants = Al + CuO
Products = Cu + Al2O3
So the Chemical Reaction will be
Al + CuO ==> Cu + Al2O3
So the balanced equation will be,
2Al + 3CuO ==> 3Cu + Al2O3
