Question

1)So2+O2-(стрелка) SO3 2)KCIO3-(стрелка) KCI+O2

Answer 1

1) 2SO2+O2=2SO3
2)2KCIO3 -> 2KCL+3O2стрелка вверх

Answer 2

1) 2SO2 + O2 → 2SO3 - реакция соединения.

2) 2KClO3 → 2KCl + 3O2 - реакция разложения.

Answer 3

The chemical equations you provided are two examples of chemical reactions:

1. Formation of sulfur trioxide (SO3) from sulfur dioxide (SO2) and oxygen (O2):

SO2 + O2 → SO3

In this reaction, sulfur dioxide (SO2) reacts with oxygen (O2) to produce sulfur trioxide (SO3).

2. Decomposition of potassium chlorate (KClO3) into potassium chloride (KCl) and oxygen gas (O2):

2 KClO3 → 2 KCl + 3 O2

In this reaction, potassium chlorate (KClO3) decomposes into potassium chloride (KCl) and oxygen gas (O2).

Please note that the arrow (→) indicates the direction of the reaction, showing the transformation of reactants into products. The numbers in front of the chemical formulas are the stoichiometric coefficients, representing the balanced ratio of reactants and products in the chemical equation. It ensures that the law of conservation of mass is obeyed, meaning the total mass of reactants equals the total mass of products.
