Guys please I need an answer for this asap Mg+2HCl -> MgCl+H2

0.2 mole of mg reacted with 0.2 of HCl

What is the mass of hydrogen gas produced?

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion

Which statement is true about hcl? (5 points) select one: a. it is a salt because it increases the concentration of metallic ions. b. it is a salt because it is formed by the reaction of an acid and a base. c. it is an acid because it increases the concentration of hydroxyl ions. d. it is an acid because it increases the concentration of hydronium ions.

Determine the reaction and balance the following equations urgent due in the morning
