Make up and find the coefficients for the equations of chemical reactions: a) combustion of hydrogen; b) combustion of lithium; c) the interaction of hydrogen and chlorine; D) combustion of carbon; e) combustion of aluminum; f) interaction of hydrogen and sulfur C) decomposition of water

a) 2H2 + O2 = 2H2O – hydrogen is oxidized to form water.
b) 4Li + O2 = 2Li2O – when lithium burns, lithium oxide is formed.
c) H2 + Cl2 = 2HCl – hydrogen interacts with chlorine, forming hydrogen chloride.
d) C + O2 = CO2 – when carbon burns, carbon dioxide is formed.
e) Al + O2 = Al2O3 – oxidizing aluminum forms its oxide.
f) H2 + S = H2S – hydrogen combines with sulfur to form hydrogen sulfide.
c) H2O = H2 + O2 – under the action of an electric current, water is decomposed into hydrogen and oxygen.
