I am writing this sentence because the answer does not reach the 20 character limit. Thank you have nice day! :D Cx :P
one mole of sulfuric acid will contain 2 moles of hydrogen atoms. The molar mass of sulfuric acid is 98.0795 g/mol. This means that every mole of sulfuric acid has a mass of 98.0795 g. Since you're dealing with one mole of sulfuric acid, it follows that you will also be dealing with two moles of hydrogen.
B. since Phosphorus has an atomic mass of 30.974 (larger) than Magnesium which is 24.305 (smaller)
And an endothermic reaction, always treat heat as a reactant
