Question

Magnesium reacts with HCl according to the balanced equation:Mg (s) + 2 HCl (aq) --> MgCl2 (aq) + H2 (g)What is the correct mole to mole factor needed to find how much HCl is needed to react with 24.31 g of Mg?

Answer 1

`1\text{ mole Mg to 2 moles HCl}`

Step-by-step explanation:

Here, we want to get the correct mole-to-mole factor

From the balanced equation of reaction, 1 mole of magnesium solid reacts with 2 moles of hydrochloric acid

Hence, the mole to mole factor according to the balanced equation given is

`1\text{ mole Mg to 2 moles HCl}`
