Answer:
Theoretical yield of hydrogen is 1.11 g
Explanation:
Balanced equation, 
As Mg remain present in excess therefore HCl is the limiting reagent.
According to balanced equation, 2 moles of HCl produce 1 mol of
.
Molar mass of HCl = 36.46 g/mol
So, 40.0 g of HCl =
of HCl = 1.10 moles of HCl
Hence, theoretically, number of moles of
are produced from 1.10 moles of HCl = 
Molar mass of
= 2.016 g/mol
So, theoretical yield of
= 
An exothermic reaction is a type of reaction that dissipates heat as the reaction proceeds. This would mean that in a closed system, when a reaction proceeds and is endothermic, the temperature of the solution or the system would increase so as to maintain the equilibrium with the whole system.

Answer:
Lithium will lose about 2 electrons
Making it a cation
Answer:
<h3>it is hydrogen gas </h3>
3. the chemical equation is :
MgSO4 ( s ) + H2SO4 (aq)-->
MgSO4 (aq) + CO2 (g) + H2O (I)
THE IONISING OF H2SO4 IN SOLUTION IS CONPLEX
