Question

А)AgNO3+CaCl2 =?+? Б)Al+CuO = ?+? В) ВаСl2+H2SO4 = ?+?

Answer 1

2AgNO3 + CaCl2 = 2AgCl + Ca(NO3)2

2Al + 3CuO = Al2O3 + 3Cu

BaCl2 + H2SO4 = BaSO4 + 2HCl

Answer 2

А) AgNO3 + CaCl2 = ? + ?

The reaction between silver nitrate (AgNO3) and calcium chloride (CaCl2) results in the formation of silver chloride (AgCl) and calcium nitrate (Ca(NO3)2).

The balanced chemical equation for this reaction is:

2 AgNO3 + CaCl2 → 2 AgCl + Ca(NO3)2

So, when silver nitrate reacts with calcium chloride, it produces silver chloride and calcium nitrate.

Б) Al + CuO = ? + ?

When aluminum (Al) reacts with copper(II) oxide (CuO), it forms aluminum oxide (Al2O3) and copper (Cu).

The balanced chemical equation for this reaction is:

2 Al + 3 CuO → Al2O3 + 3 Cu

So, when aluminum reacts with copper(II) oxide, it produces aluminum oxide and copper.

В) ВаCl2 + H2SO4 = ? + ?

When barium chloride (BaCl2) reacts with sulfuric acid (H2SO4), it forms barium sulfate (BaSO4) and hydrochloric acid (HCl).

The balanced chemical equation for this reaction is:

BaCl2 + H2SO4 → BaSO4 + 2 HCl

So, when barium chloride reacts with sulfuric acid, it produces barium sulfate and hydrochloric acid.

Please note that these reactions are balanced chemical equations and represent the stoichiometric ratios of the reactants and products.
