Answer:
NaHCO3 + HCl --> NaCl + CO2 + H2O
Explanation:
NaHCO3 which is an acidic salt because of the replaceable H+ (Bronste lowry acid), by definition acid dissociates in water to release a proton.
NaHCO3 dissociates in water to give Na+, H3O+ and HCO3-
Stomach acid which is HCl also dissociates in water to give H3O+ and Cl-
The H3O+ and HCO3- combines briefly to form a weak carbonic acid almost immediately, which then further dissociates to form H2O and CO2. CO2 is burped out from the mouth.
Na+ and Cl- combines to form NaCl in water which is a table salt solution.

Answer:
False
Explanation:
Fossil fuels are used as a source of energy to this day.
The complete reaction of the problem, for better illustration, is
FeO(s) + CO(g) <--> Fe(s) + CO2(g)
The double-tailed arrow signifies that the reaction is in a dynamic chemical equilibrium. When the system is in equilibrium, the forward and the backward reaction rates have an equal ratio of Kp = 0.403 at 1000°C. The formula for Kp is
Kp = [partial pressure of products]/[partial pressure of reactants]
So, first, let's find the partial pressure of the compounds in the reaction.
FeO(s) + CO(g) <--> Fe(s) + CO2(g)
Initial x 1.58 0 0
Change -1.58 -1.58 +1.58 +1.58
------------------------------------------------------------------
Equilbrium x-1.58 0 1.58 1.58
Kp = [(1.58)(1.58)]/[(x-1.58)] = 0.403
x = 7.77 atm (this is the amount of excess FeO)
Therefore, the partial pressure of CO2 at equilibrium is 1.58 atm. There is no more CO because it has been consumed due to excess FeO.
