Question

Тема: Классы неорганических соединений. Соли. MgO + HCl → NaOH + HNO3 → Na2SO4 + BaCl2 →

Answer 1

Ответ:

MgO + 2HCl = MgCl2 + H2O

NaOH + HNO3 = NaNO3 + H2O

BaCl2+Na2SO4 = BaSO4(осадок)+2NaCl

Answer 2

$MgO+2HCl=>MgCl_2+H_2O$

$NaOH+HNO_3=>NaNO_3+HOH(H_2O)$

$Na_2SO_4+BaCl_2=>2NaCl+BaSO_4\downarrow$

Answer 3

Classes of Inorganic Compounds: Salts

Salts are a class of inorganic compounds that are formed when an acid reacts with a base. They are composed of positively charged ions, known as cations, and negatively charged ions, known as anions. Salts are typically solid at room temperature and have high melting and boiling points.

Let's look at the reactions you provided:

1. MgO + HCl → MgCl2 + H2O: - In this reaction, magnesium oxide (MgO) reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and water (H2O).

2. NaOH + HNO3 → NaNO3 + H2O: - In this reaction, sodium hydroxide (NaOH) reacts with nitric acid (HNO3) to form sodium nitrate (NaNO3) and water (H2O).

3. Na2SO4 + BaCl2 → BaSO4 + 2NaCl: - In this reaction, sodium sulfate (Na2SO4) reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4) and sodium chloride (NaCl).

It's important to note that these reactions are just examples, and there are many other possible reactions involving salts. The specific products formed depend on the reactants used and the conditions of the reaction.

I hope this helps! Let me know if you have any further questions.
