A student reacts Mg and HCl together. The product of this reaction is H, gas and MgCl2. The balanced equation for this reaction is
Mg + 2HCI - H2 + MgCl2
If I need to create 50 L of Hy, how many moles of HCI should I start with?
a) 2.3 mol HCI
b) 4.5 mol HCI
c) 1.1 mol HCI
d) 44.6 mol HCI

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

D.na is the answer hope this

Hello,#agreed with joseph002.i got my source also from  source: hope this

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
