Make formulas of hydrogen compounds with non-metals: silicon, nitrogen and sulfur. indicate compounds with the most pronounced acids.

Explanation of the solution to the problem: using the periodic system of chemical elements of D.I. Mendeleev, you can make up the necessary hydrogen compounds. Firstly, there are general formulas of hydrogen compounds of elements of 4-7 groups, and secondly, the second element in hydrogen compounds is in its minimum oxidation state (min. CO is according to the formula 8-No. of the group in which the element is located), that is, for silicon min. CO = 8-4 = 4; for nitrogen – 8-5 = 3; for sulfur – 8-6 = 2. These oxidation states have a “-” sign.
SiH4 is a compound that is mainly involved in redox reactions.
NH3 – ammonia – has strong basic properties.
H2S is hydrosulfuric acid, that is, it has the most pronounced acidic properties.
