Question

How many grams of hydrogen gas will be produced from the reaction of zinc metal with 85 grams of hydrochloric acid

Answer 1

2.4 grams of H

Step-by-step explanation:

Zn+2HCl=ZnCl2+H2

85gHCI x 1 mol HCI/36.458 g HCI x 1 mol H/2 mol HCI x 2.016 g H/1 mol H = 2.4 g H. (I know this is kinda hard to read, but I had the same question for my test and this is what I did to get 2.4. I hoped this helped)
