2Al + 3CuCl2 ------> 3Cu + 2AlCl3
from reaction 2 mol 3 mol
given 0.357 mol x mol
x= 0.375*3/2 = 0.563 mol CuCl2
The answer would be Groups, or also known as families.
Answer:
C.3
Explanation:
The coefficient is the number of molecules needed for a set of reactions. The different reactions will have a different coefficient, so you have to balance the reaction first by knowing all the reactants and the product the reaction. The balanced reaction for sulfuric acid and aluminum hydroxide is:
2 Al(OH)3(s) + 3 H2SO4(aq) -----> Al2 (SO4)3(aq) + 6 H2O(l)
Every set of reactions will need 3 molecules of sulfuric acid and 2 molecules of aluminum hydroxide. The coefficient in front of sulfuric acid (H2SO4) is 3.
