Question

Baking soda (sodium bicarbonate) decomposes when it is heated:
2 NaHCO31s2 ∆ Na2CO31s2 + CO21g2 + H2O1g2
ΔH° = + 136 kJ
Consider an equilibrium mixture of reactants and products in a closed container. How does the number of moles of CO2 change when the mixture is disturbed by the following:
(b) Adding water vapor

Accepted Answer

Hello everyone. And this problem being asked what will happen to the number of moles of NH three when hcl is added to the mixture to be more exact. We're talking about this equation right over here where um ammonium chloride decomposes into ammonia and hydrogen chloride. Alright, so we can recognize that Hcl is one of our products here in our chemical reaction. So if we're gonna go ahead and add more hcl, this will cause the reaction to shift to the left. So this way, So NH three and HCL will react to form this product until our equilibrium is reestablished. So we can write for our final answer then, is that the number of moles Of Ammonia, which is NH 3? We'll go ahead and decrease. So this is going to be my final answer for this problem.
