Question

Отметьте вещества , которые относятся к классу солей: а) СаС2; б) Ni(NO3)2; в) LiF; г) C2H6; д) NaHCO3;

Answer 1

Соли, это химические соединения, состоящие из катионов и анионов.
CaC2-- Ca2+ катион С2 2- анион(ацетилен проявляет свойства очень слабой кислоты)--соль
Ni(N)3)2--Ni2+ катион NO3- анион--соль
LiF-- Li+ катион F- анион--соль
NaHNO3-- Na+ катион HNO3- анион--соль
С2H6-углеводород

Answer 2

Substances that belong to the class of salts:

а) CaC2 - Calcium carbide is not a salt. It is a chemical compound used in the production of acetylene gas and various other industrial applications. б) Ni(NO3)2 - Nickel(II) nitrate is a salt. It is an inorganic compound composed of nickel and nitrate ions. It is commonly used in electroplating and as a catalyst in various chemical reactions. в) LiF - Lithium fluoride is a salt. It is an inorganic compound composed of lithium and fluoride ions. It is used in the production of ceramics, glass, and as a component in some dental materials. г) C2H6 - Ethane is not a salt. It is an organic compound and a hydrocarbon. Ethane is a colorless and odorless gas that is commonly used as a fuel. д) NaHCO3 - Sodium bicarbonate, also known as baking soda, is a salt. It is an inorganic compound composed of sodium, hydrogen, carbon, and oxygen ions. Sodium bicarbonate is commonly used as a leavening agent in baking and as an antacid to relieve heartburn. To summarize, the substances that belong to the class of salts are: - Ni(NO3)2 (Nickel(II) nitrate) - LiF (Lithium fluoride) - NaHCO3 (Sodium bicarbonate)
