1) What interacts with hydrogen to form pure metals? 2) What acids are composed of hydrogen and a non-metal of group 6 or 7? 3) Which acid easily decomposes into carbon dioxide and water? 4) What acid is the “bread” of the chemical industry? 5) What is formed in oxygen when hydrogen burns?

1). When metal oxides react with hydrogen, pure metals are formed.

2). Hydrogen and non-metal 6, 7 groups consist of acids: H2S (hydrogen sulfide), H2Se (hydrogen selenic), H2Te (hydrogen telluric), HCl (hydrochloric), HI (hydrogen iodine), HBr (hydrogen bromide), HF (hydrogen fluoride).

3). Carbonic acid readily decomposes into carbon dioxide and water:

H2CO3 = CO2 + H2O

4). The “bread” of the chemical industry is sulfuric acid (H2SO4).

5). When hydrogen burns in oxygen, water is formed:

2H2 + O2 = 2H2O
