Question

Допишите уравнения реакций, если они возможны: H2CO3+CaCI2= Mg+H3PO4= HCI+BA(OH)2= CaP+SO2=

Answer 1

H2CO3+CaCl2=2HCl+CaCO3
3Mg+2H3PO4=Mg3(PO4)2+3H2
2HCl+Ba(OH)2=2H2O+BaCl2
CaО+SO2=CaSO4

Answer 2

H2CO3 + CaCl2 = ?

The reaction between carbonic acid (H2CO3) and calcium chloride (CaCl2) is possible. It can be represented by the following balanced chemical equation:

H2CO3 + CaCl2 → CaCO3 + 2HCl [[1]]

In this reaction, carbonic acid reacts with calcium chloride to form calcium carbonate (CaCO3) and hydrochloric acid (HCl).

Mg + H3PO4 = ?

The reaction between magnesium (Mg) and phosphoric acid (H3PO4) is also possible. The balanced chemical equation for this reaction is:

3Mg + 2H3PO4 → Mg3(PO4)2 + 3H2 [[2]]

In this reaction, magnesium reacts with phosphoric acid to form magnesium phosphate (Mg3(PO4)2) and hydrogen gas (H2).

HCl + Ba(OH)2 = ?

The reaction between hydrochloric acid (HCl) and barium hydroxide (Ba(OH)2) is possible. The balanced chemical equation for this reaction is:

2HCl + Ba(OH)2 → BaCl2 + 2H2O [[3]]

In this reaction, hydrochloric acid reacts with barium hydroxide to form barium chloride (BaCl2) and water (H2O).

CaP + SO2 = ?

The reaction between calcium phosphide (CaP) and sulfur dioxide (SO2) is not possible. Calcium phosphide does not react with sulfur dioxide under normal conditions.
