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

Yes, a reaction will occur. Potassium chloride react with bromine to produce potassium bromide and chlorine would take place in a boiling solution.
Answer:
Protons, neutrons, electrons..
Explanation:
Protons and neutrons consist of quarks which are stuck together by tiny things called gluons.
Hope this helps! :)
Volume of solute = 25 mL
Volume of solvent = 150 mL
% = ( volume of solute / volume of solvent ) x 100
% = ( 25 / 150 ) x 100
% = 0,166 x 100
= 16.6 % v/v
hope this helps!
<span>A theory which repeatedly fails to confirm the expected predictions probably should be discarded. If the given theory is failing once or twice, then the facts and figures can be researched much more to understand the real cause of the error caused. But in case, the theory is again and again fails to confirms the expected predictions, then there is a gap in the facts and figures and the theory being studied and hence it should be discarded.</span>
