0.22 moles of Al₂(CO₃)₃
Explanation:
The decomposition reaction of aluminium carbonate (Al₂(CO₃)₃):
Al₂(CO₃)₃ → Al₂O₃ + 3 CO₂
Taking account the chemical reaction we devise the following reasoning:
if 1 mole of Al₂(CO₃)₃ produces 3 moles of 3 CO₂
then X moles of Al₂(CO₃)₃ produces 0.65 moles of 3 CO₂
X = (1 × 0.65) / 3 = 0.22 moles of Al₂(CO₃)₃

A/a physical change is when an object goes through a natural change such as weather etc.
B/ the different is that 1) chemical change is more quick to change rather than physical (ex: I’d there is rocks flying around and is wearing down another rock it would take longer rather than acid)
Answer: Ice is less dense than water.
Explanation: As water freezes, it expands, making it less dense. This is why ice cubes float in a glass of water.
