Answer:
317 g
Explanation:
Cu + 2HCl --> CuCl2 +H2
1 : 2 1 : 1
1 mole of Cu = 63.5 g
1 mole of H2 = 2g
1 mole Cu produces = 1 mole of H2
63.5 g of Cu produces = 2 g of H2
So
10 g of H2 will be produced from = (63.5/2)*10 = 317 g of Copper
Yes barium carbonate forms a ppt. it is insoluble in water
That’s because of gravity
The answer is A it’s tall
The answer is: 4.00 mol of Fe(OH)2 is produced.
Balanced chemical reaction:
Fe(s) + 2NiO(OH)(s) + 2H₂O(l) → Fe(OH)₂(s) + 2Ni(OH)₂(aq).
n(Fe) = 5.00 mol; amount of iron.
n(NiO(OH)) = 8.00 mol; amount of nickel oxide hydroxide, limiting reactant.
From chemical reaction: n(NiO(OH)) : n(Fe(OH)₂) = 2 : 1.
n(Fe(OH)₂) = 8 mol ÷ 2.
n(Fe(OH)₂) = 4 mol; amount of iron(II) hydroxide.
