Question

Какое количество вещества магния необходимо для реакции с 2 моль брома

Answer 1

2Mg+2Br2=2MgBr2
Ответ : 2 моль

Answer 2

Magnesium Reacting with Bromine

To determine the amount of magnesium needed to react with 2 moles of bromine, we can use the balanced chemical equation for the reaction between magnesium and bromine:

Mg + Br2 → MgBr2

From the balanced equation, we can see that 1 mole of magnesium reacts with 1 mole of bromine to produce 1 mole of magnesium bromide. Therefore, to react with 2 moles of bromine, we would need 2 moles of magnesium.

This information is based on the stoichiometry of the chemical reaction between magnesium and bromine.
