describe un modelo matemático para representar lo que sucede en cada una de las reacciones químicas  (incluye toda la simbología que puedas) y clasifícalas según consideres de acuerdo con lo abordado en el tema.
1. El hidrógeno molecular reacciona con el oxígeno molecular y produce agua

2. El Óxido de calcio reacciona con el agua y produce hidróxido de calcio

3. El sulfuro de hierro (II) se produce cuando reacciona el azufre y el hierro en su forma atómica

4. El ácido sulfuroso se descompone por la acción de calor en dióxido de azufre gaseoso y agua

5. El carbonato de calcio se descompone por la acción de calor en oxido de calcio y dióxido de carbono gaseoso.

6. El magnesio reacciona con el ácido clorhídrico y produce dióxido de magnesio e hidrógeno gaseoso.

Answer 1

Responder:

2H2 + O2 → 2H2O

CaO + H2O → Ca (OH) 2

Fe + S → FeS

H2SO3 → SO2 + H2O

CaCO3 → CaO + CO2

Explicación:

2H2 + O2 → 2H2O

2 moléculas de hidrógeno gaseoso reaccionan con oxigente para producir 2 moléculas de agua

CaO + H2O → Ca (OH) 2

El óxido de calcio reacciona con el agua para producir hidróxido de calcio.

Fe + S → FeS

El hierro reacciona con el azufre para producir sulfuro de hierro.

H2SO3 → SO2 + H2O

Por descomposición, el ácido sulfuroso se descompone para producir dióxido de azufre y agua.

CaCO3 → CaO + CO2

El carbonato de calcio se descompone para producir óxido de calcio y dióxido de carbono.
