Answer:
0.80 Moles of Hydrochloric Acid would be required to produce 0.40 Moles of hydrogen gas due to the equation ratios
Step-by-step explanation:
How many moles of hydrochloric acid are required to produce .40 moles of hydrogen gas?
Hydrochloric acid = HCl
Hydrogen gas = H2
H = 1+
Cl = 1-
HCL = H2 + Cl2
2HCl = H2 + Cl2
2:1:1
0.80 = 0.40 + 0.40
