The bonds of the product store 27 KJ more energy than the bonds of the reactants how is energy conserved during this reaction
Blababa [14]

If the bonds of the product store 27 KJ more energy than the bonds of the reactants, It means the surroundings absorb 27 kj of energy from the reaction system Hence, Option (D) is the correct answer

<h3>What is the Exothermic reaction ?</h3>

An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.

The bonds of the product store 27 KJ more energy than the bonds of the reactants, It means that energy has been absorbed by the surrounding as the product formed is more stable due to more stronger bond

This can be inferred from more stored energy with in the bonds and Thus, It is a exothermic reaction.Hence, Option (D) is the correct answer

Convert the following into balanced equations:
sesenic [268]

Gallium metal is heated in oxygen gas, it melts and forms solid gallium(III) oxide.

             Ga + O₂⇒   Ga O₂

Balance the atoms with simple - whole coefficients.

4 Ga + 3 O₂   2 Ga₂O₃.

Specify the states of matter.

4 Ga(s)  + 3 O₂ (g) ⇒   2 Ga₂O₃.(s)

Therefore, balanced equation is----- 4 Ga(s)  + 3 O₂ (g)  ⇒ 2 Ga₂O₃.(s)

What is the balanced formula equation?

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

Why are equations balanced?

A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.
