Question

NO2 + O2 + H2O > HNO3 CH4 + O2 > CO2 + H2O Fe2 O3 + CO > FE + CO2 CaO + P2 O5 > Ca3 (PO4) MnO + SiO2 > MnSiO3

Answer 1

Ответ:

CH4+2O2=CO2+2H2O

Fe2O3+3CO=2Fe+3CO2

3CaO+P2O5=Ca3(PO4)2

2Mn+3SiO2=2MnSiO3

Answer 2

The given chemical equation is a combination of several reactions. Let's break it down step by step:

1. NO2 + O2 + H2O → HNO3 + CH4 + O2 This equation represents the reaction between nitrogen dioxide (NO2), oxygen (O2), and water (H2O) to produce nitric acid (HNO3), methane (CH4), and oxygen (O2).

2. Fe2O3 + CO → Fe + CO2 This equation represents the reaction between iron(III) oxide (Fe2O3) and carbon monoxide (CO) to produce iron (Fe) and carbon dioxide (CO2).

3. CaO + P2O5 → Ca3(PO4)2 This equation represents the reaction between calcium oxide (CaO) and phosphorus pentoxide (P2O5) to produce calcium phosphate (Ca3(PO4)2).

4. MnO + SiO2 → MnSiO3 This equation represents the reaction between manganese(II) oxide (MnO) and silicon dioxide (SiO2) to produce manganese silicate (MnSiO3).

Please note that these equations represent simplified reactions and may not include all the necessary conditions or stoichiometric coefficients.
