Answer:

The answers to your question are given below

Explanation:

The equation for the reaction is given below:

2KClO₃ —> 2KCl + 3O₂

The total number of each atoms present in the reactants and products can be obtained by doing a head count as illustrated below:

Reactants >>>>>> Number of atoms

Potassium (K) >>> 2 × 1 = 2

Chlorine (Cl) >>>> 2 × 1 = 2

Oxygen (O) >>>>> 2 × 3 = 6

Products >>>>>>> Number of atoms

Potassium (K) >>> 2 × 1 = 2

Chlorine (Cl) >>>> 2 × 1 = 2

Oxygen (O) >>>>> 3 × 2 = 6

How do you if a reaction is exthermic
Artist 52 [7]

Answer:

To know if a reaction/experiment is exothermic or endothermic depends on the temperatures of the two liquids you are trying to mix. First before mixing your liquids take the temperature of both of them and write it down. then mix both liquids together to get your reaction and take the temperature of both mixed together. write it down. Did the temperature of your liquids increase or decrease? this question will determine weather the reaction was endothermic or exothermic. Endothermic meaning the temperature got cooler and Exothermic meaning the temperature got hotter/warmer

EX. | starting temperature- 72 F | ending temperature- 82 F | Exothermic

EX 2. | starting temperature- 72 F | ending temperature- 69 F | Endothermic

Explanation: I hope this helped you :)

This reaction releases energy as heat. Explain whether it obeys the law of conservation of energy.
Anon25 [30]
The reaction that releases energy as heat is called an Exothermic reaction. This reaction does obey the law of conservation by preserving the energy present in the molecule and converting it to thermal heat to maintain it's from. Most reactions obey the law of conservation of energy.
