Write the equation for the reactions of compounds between simple substances, leading to the formation of binary compounds: a) oxygen and copper, b) aluminum and sulfur, c) sodium and hydrogen

Binary compounds are substances that are made up of atoms of two different elements. Formed as a result of the reaction of the combination of two simple substances.
a) O2 + 2Cu = 2 CuO (copper oxide)
b) 2Al + 3S = Al2S3 (aluminum sulfide)
c) 2Na + H2 = 2NaH (sodium hydride)
