groups are the rows on the periodic table
i guess so
We have a balanced equation:
2 Al+ 3 CuSO4 ⇒ Al2(SO4)3+ 3 Cu
1.85 g Al* (1 mol Al/ 26.98 g Al)* (3 mol Cu/ 2 mol Al)* ( 63.55 g Cu/ 1 mol Cu)= 6.54 g Cu.
(Note that the units cancel out so you get the answer)
6.54 g Cu* (56.6/100)= 3.70 g Cu.
The final answer is 3.70 g Cu~
Since there are no choices provided for this question, the answer to why many scientists reject the cold fusion theory is that the experiment by Fleischmann and Pons that had the strongest claim was found out to be flawed. Many scientists who also replicated the experiment failed to obtain positive results which further weakened the claim for cold fusion theory.
