Answer: C. CO₂ and H₂O
Explanation:
Combustion reactions produce carbon dioxide and water.
Packets of light energy are called photons.
Actual yield/Theoretical yield *100= Percentage yield. So Actual yield = Percentage yield*Theoretical yield.
Therefore actual yield= 90/100 * 1.09g = 0.98g
Actual yield: 0.98 g
Avogadros number is the answer
