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

Answer:
Just say I wonder why teachers give homework :/
Explanation:
Explanation:
Dissolve 93.52g of NaCl in about 400mL of distilled water, then add more water until final volume is 800mL. If starting with a solution or liquid reagent: When diluting more concentrated solutions, decide what volume(V2) and molarity (M2) the final soluble should be.
Answer: It would have a high pitch.
Explanation: since the whistle has a high frequency, I can infer that it will have a high pitch.
Answer:
We can just use the formula for the volume of sphere which is 4/3 PI R cubed R is the radius. So if you have a balloon that's a sphere.
