Answer:
1.67×10^25 molecules
Explanation:
No of molecules = no of moles × Avogadros number
No of moles= mass in gram / molar mass
No of moles of water in given sample = 500.3/18
= 27.79 moles
No of molecules = 27.79× 6.02×10^ 23
= 167.32×10^23 or 1.67×10^25
Answer:
No.

Answer: Part 1: The reaction is considered as replacement reaction and produce preciptate.
Part 2: Due to Mg is more active than Al.
Explanation:
Part 1: the reaction is replacement reaction due to the ions is replaced with each other as this equation shows:
MgCl2 + Na2CO3 → MgCO3 + 2NaCl
and MgCO3 is a white precipitate.
Part 2:
Al reacts with CuCl2 because Al is more active than Cu.
Al can not react with MgCl2 because Mg is more active than Al.
