Question

• AgNO3 + ? = Ag3PO4 + ?• ? + Li CO3 = ? + CO2 + H2O• BaBrz + ? = BaSO4 + ?​

Answer 1

Ответ:

1. 3AgNO3+H3PO4=Ag3PO4+3HNO3

2. 2HNO3+Li2CO3= 2LiNO3+H2O+CO2

3. BaBr2+ H2SO4=BaSO4+2HBr

Answer 2

Let's balance the chemical equations you provided:

1. AgNO3 + ? = Ag3PO4 + ?

To balance this equation, we need to determine the missing reactant and product. The reaction involves the precipitation of silver phosphate (Ag3PO4) from silver nitrate (AgNO3). The balanced equation is:

3 AgNO3 + Na3PO4 → Ag3PO4 + 3 NaNO3

In this balanced equation, sodium phosphate (Na3PO4) is the missing reactant, and sodium nitrate (NaNO3) is the missing product.

2. ? + LiCO3 = ? + CO2 + H2O

To balance this equation, we need to identify the missing reactant and product. This reaction involves the decomposition of lithium carbonate (LiCO3) into carbon dioxide (CO2) and water (H2O). The balanced equation is:

2 LiCO3 → 2 LiOH + CO2 + H2O

In this balanced equation, lithium hydroxide (LiOH) is the missing product.

3. BaBr2 + ? = BaSO4 + ?

To balance this equation, we need to determine the missing reactant and product. The reaction involves the precipitation of barium sulfate (BaSO4) from barium bromide (BaBr2). The balanced equation is:

BaBr2 + Na2SO4 → BaSO4 + 2 NaBr

In this balanced equation, sodium sulfate (Na2SO4) is the missing reactant, and sodium bromide (NaBr) is the missing product.

Please note that in chemical equations, the missing reactants or products can vary depending on the specific reaction conditions. The balanced equations provided above are based on common reactions involving the given compounds.
