Question

H2CO3+Ca(NO3)2= Fe(NO3)3+AlPO4= PbO4+CuCO3= Написать в молекулярном, полном и сокращенном виде.

Answer 1

1. H₂CO₃ + Ca(NO₃)₂ = CaCO₃↓+ 2HNO₃
    2H⁺ + CO₃²⁻ + Ca²⁺ + 2NO₃⁻ = CaCO₃↓ + 2H⁺ + 2NO₃⁻
    Ca²⁺ + CO₃²⁻ = CaCO₃

2. Fe(NO₃)₃ + AlPO₄ ≠
3. PbSO₄ + CuCO₃ ≠

Answer 2

Reaction 1: H2CO3 + Ca(NO3)2

The reaction between H2CO3 (carbonic acid) and Ca(NO3)2 (calcium nitrate) can be represented as follows:

H2CO3 + Ca(NO3)2 → CaCO3 + 2 HNO3

In molecular form: Carbonic acid + Calcium nitrate → Calcium carbonate + Nitric acid

In full form: Hydrogen carbonate + Calcium nitrate → Calcium carbonate + Nitric acid

In simplified form: H2CO3 + Ca(NO3)2 → CaCO3 + 2 HNO3

Reaction 2: Fe(NO3)3 + AlPO4

The reaction between Fe(NO3)3 (iron(III) nitrate) and AlPO4 (aluminum phosphate) can be represented as follows:

Fe(NO3)3 + AlPO4 → FePO4 + Al(NO3)3

In molecular form: Iron(III) nitrate + Aluminum phosphate → Iron(III) phosphate + Aluminum nitrate

In full form: Iron(III) nitrate + Aluminum phosphate → Iron(III) phosphate + Aluminum nitrate

In simplified form: Fe(NO3)3 + AlPO4 → FePO4 + Al(NO3)3

Reaction 3: PbO4 + CuCO3

The reaction between PbO4 (lead(IV) oxide) and CuCO3 (copper(II) carbonate) does not occur. PbO4 is not a stable compound, and copper(II) carbonate does not react with it.

Therefore, there is no balanced chemical equation for this reaction.

Please note that the reaction you provided, PbO4 + CuCO3, does not represent a valid chemical reaction.

Molecular, Full, and Simplified Forms

Molecular form represents the reaction using the chemical formulas of the reactants and products.

Full form represents the reaction using the names of the reactants and products.

Simplified form represents the reaction using the chemical formulas of the reactants and products, but without indicating the state of matter or the coefficients.

Here are the molecular, full, and simplified forms for the reactions mentioned above:
