I have attached the experiment which was the molar ratio. please answer Q1,2, and 3

Q2: How do the concepts of moles and molar ratios help define the changes in chemical reactions? Q3: How can we use the masses of reactants and products to verify the molar ratios in a balanced equation?| Data Sheet-Show all your work in the calculations to receive full credit NaHCO3(s)+HCl(aq)NaCl(aq)+CO2(g)+H2O(I) 9.
