Arrange the chemical formulas of substances in the following order: gas, liquid substance, toxic chemical compound, food additive, radioactive metal: 1) KCN 2) Hg 3) NaHCO3 4) Sg 5) CH4

5) CH4 – methane – a colorless gas (under normal conditions), odorless, the simplest hydrocarbon;
2) Hg – mercury – metal, under normal conditions it is in a liquid state of aggregation, the vapors are extremely toxic;
1) KCN – potassium cyanide – the strongest inorganic poison, as a result of which cells lose their ability to absorb oxygen from the blood;
3) NaHCO3 – sodium bicarbonate (baking or baking soda, bicarbonate soda) – used in the food industry, in cooking;
4) Sg – seborgium – a short-lived radioactive element with atomic number 106 in the periodic system of D.I.Mendeleev.
