The equation demonstrates a reaction of methane and oxygen CH4 + 2O2 > CO2 + 2H2O
In order for the reaction to proceed, for every one mole of methane(CH4), there must be at least how many mole(s) of oxygen

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.
