How many moles of H2s are produced when 2.25 moles Hcl react with excess zns
svlad2 [7]

Answer:

1.125 moles of H2S

Explanation:

From 2HCl(aq) + ZnS(s) ---------> H2S (g) + ZnCl2 (aq)

From the reaction equation;

2 moles of HCl produces 1 mole of H2S

Therefore 2.25 moles of HCl will produce 2.25 ×1/2 = 1.125 moles of H2S

Recall that it was explicitly stated in the question that ZnS is the reactant in excess. This implies that HCl is the limiting reactant and controls the amount of product obtained.

What is the molar mass for a gas that effuses 0.344 times as fast as hydrogen gas?
Leona [35]
Rate of effusion gas/rate of effusion H2   =    √(M(H2))/√(M(gas))
0.344= √2/√(M(gas))
√(M(gas))= √2/0.344
M(gas)= (√2/0.344)² =2/(0.344)² ≈16.9

When cobalt chloride is added to pure water, the co2 ions hydrate?
mrs_skeptik [129]
Answer : The question is incomplete and the complete question is attached in the answer;

Answer 1) When HCl was added to the system of cobalt chloride it will eventually produce more Cl ions in the solutions which will shift the equilibrium to the right and make the solution look more blue than before. To accommodate extra Cl ions in the system the equilibrium gets shifted. 

Answer 2) When in the reaction system water is added the Cobalt chloride compound forms a hydrated mixture; this means the equilibrium reaction shifts to the left and produces more hydrated ions along with more chlorine ions in the solution.

Which then turns the resultant solution tinto pink in colour.
