Mg+HCL=
CaCO3+HCL=
Срочно​

Answer 1

Ответ:

Объяснение:

HCl + KOH = KCl + H2O

HCl + NaHCO3 = NaCl + CO2↑ + H2O

Mg + 2HCl = MgCl2 + H2↑

CaCO3 + 2HCl = CaCl2 + CO2↑ + H2O

Answer 2

$HCl + KOH = KCl + H_{2}O \\ </p><p>HCl + NaHCO_{3} = NaCl + CO_{2} + H_{2}O \\ </p><p>Mg + 2HCl = MgCl_{2} + H_{2} \\ </p><p>CaCO_{3} + 2HCl = CaCl_{2} + CO_{2} + H_{2}O$
