I see that you are trying to predict the products and calculate the moles of sodium (Na) produced in the given reaction. The balanced reaction you have is:
2 NaHCO₃ (s) -> 2 Na (s) + H₂ (g) + 2 C (s) + 3 O₂ (g)
To calculate how many moles of Na are produced per mole of NaHCO₃ used, you need to consider the coefficients in the balanced equation. In this case, for every 2 moles of NaHCO₃ consumed, 2 moles of Na are produced.
Therefore, if you start with a certain number of moles of NaHCO₃, you can use this ratio to determine how many moles of Na would be produced based on the stoichiometry of the reaction. This allows you to relate the amounts of reactants and products in a chemical reaction.
Remember, stoichiometry is a key concept in chemistry that helps us understand the quantitative relationships in chemical reactions. It's important to use the balanced equation and stoichiometric coefficients to make accurate predictions about the amounts of substances involved in a reaction.
