total ionic equation (also known as the complete ionic equation) for the reaction of potassium carbonate with hydrochloric acid
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
HCl(aq) + NaHCO3(s) --> NaCl(aq) + H2O(l) + CO2(g)
Exothermic reaction is a reaction which gives out heat. For example: when natural gas burns it release its energy to the surroundings which could be the water in a central heating system. this is a EXOTHERMIC REACTION between natural gas and oxygen.
To further acidify the solution. The HCL removes excess sodium carbonate from the solution by reacting with it to form carbon dioxide which causes the solution to foam.
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.

HCl(aq) + NaHCO3(s) --> NaCl(aq) + H2O(l) + CO2(g)
It yields HCl+CO2, CO2 is a by product of a neutralization reaction with HCl.HCl (hydrochloric acid) if neutralized (reacted) with NaHC03 (sodium bicarbonate) will yield NaCl (table salt) + H2O (water) + CO2 (carbon dioxide)
CaCO3 + HCl --> CaHCO3 or with excess of HCl CaCO3 + 2HCl --> CaCl2 +CO2 + H2O
Exothermic reaction is a reaction which gives out heat. For example: when natural gas burns it release its energy to the surroundings which could be the water in a central heating system. this is a EXOTHERMIC REACTION between natural gas and oxygen.
it is an exothermic reaction so the best way to do the experiment is to have different mass of anhydrous sodium carbonate and react it with the water and see what temperature is suitable for you
Mixture of sodium carbonate and magnesium
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
To further acidify the solution. The HCL removes excess sodium carbonate from the solution by reacting with it to form carbon dioxide which causes the solution to foam.
Let's see. CaCO3 + 2HCl -> CaCl2 + CO2 + H2O By reacting with this acid carbon dioxide is produced, thus the bubbles of gas in the product solution.
