- burning paper
<h3>What are physical and chemical changes?</h3>
Physical changes are changes which occur in a substance which may alter the physical properties of the substance but does not affect the chemical properties of the substance. Physical changes are easily reversible
In physical changes, no new substances are formed. Example of a physical change is the melting of ice or candle wax.
Chemical changes are changes which alter the chemical properties of a substance and in which new substances are formed. Example of chemical changes are; the rusting of iron, bleaching hair silver tarnishing, frying an egg, and burning paper.
Chemical changes are not easily reversible.
In conclusion, physical changes do not produce new substances while chemical changes produce new substances.

Answer:
<u><em /></u>
- <u><em>0.225 mol O</em></u><u><em>₂</em></u>
Explanation:
<em><u>1. Balanced chemcical reaction (given):</u></em>
- 4KO₂ + 2CO₂ → 2K₂CO₃ + 3O₂
<u><em>2. Mole ratio</em></u>
Use the coefficients from the balanced chemical equation to form the mole ratio of O₂ to KO₂:
<em><u>3. How many moles of O₂ are produced when 0.300 mol of KO₂ reacts in this fashion?</u></em>
Mutiply 0.300 mol of KO₂ by the mole ratio:
