Answer:
4H₂O₂ → 4H₂O + 2O₂
Explanation:
The chemical reaction for the decomposition of hydrogen peroxide can be represented as follows;
2H₂O₂ → 2H₂O + O₂
Therefore, two molecules of hydrogen peroxide decomposes into two molecules of water and one molecule of oxygen.
In a related diagram, we have 4 molecules of hydrogen peroxide decomposing, therefore we have;
4H₂O₂ → 4H₂O + 2O₂
The attached diagram shows the products of the decomposition of the four molecules of hydrogen peroxide.
<u>Answer:</u>
<em>Burning gas on a stove top transforms chemical energy into thermal energy.</em>
<u>Explanation:</u>
Cooking food involves in two types of energies. <em>They are chemical energy and thermal energy.
</em>
We use gas for a gas stove.Here gas is chemical energy.when we light the stove the fire lits up and here the <em>chemical energy energy is converted into thermal energy.</em>
Breaking and combining of bonds during combustion gives heat and light.This thermal energy heats the vessels and cooks the food through the <em>process of conduction, convection and radiation.
</em>
Theory - an idea to explain something, or a set of guiding principles.
hypothesis - an unproven theory or statement.
fact - something that is true or something that has occurred or has been proven correct.
^^ those are just dictionary definitions but you didn’t include anything to match em with
