3. How many grams of sulfuric acid is required to react with 140.0g of zinc to produce zinc sulfate and hydrogen gas?
Zn + H2SO4= ZnSO4 + H2
I’ll mark you brainlist

The equation below shows the reaction of zinc with hydrochloric acid (hcl). zn (s) + 2 hcl (aq) —> zncl2 (aq) + h2 (g) what will happen if the concentration of hcl is decreased? a. more zncl2 will be produced. b. the reaction rate will slow down. c. the hydrochloric acid will become more acidic. d. the reaction will produce water instead of hydrogen gas.
