## anonymous one year ago The decomposition of baking soda (NaHCO3) is given in this reaction: 2NaHCO3 → Na2CO3 + H2O + CO2 If 8 moles of baking soda decompose, how many moles of Na2CO3 are produced? 1 2 4 8

This can be solved in a similar fashion. First try out yourself. I'll assist you through the process.

General Scheme for stoichiometric calculations: $$\sf \large 1.$$First write and balance an equation for the process described. $$\sf \large 2.$$Next, use the stoichiometric coefficients to find moles produced. $$\sf \large 3.$$ Set up a ratio using the species of interest, like so: e.g. for a general reaction: $$\sf \large \color{red}{a}A + \color{blue}{b}B \rightleftharpoons \color{green}{c}C$$ where upper case are the species (A,B,C), and lower case (a,b,c) are the coefficients , $$\sf \dfrac{n_A}{\color{red}{a}}=\dfrac{n_B}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}$$ From here you can isolate what you need. For example: if you have 2 moles of B, how many moles of C can you produce? solve algebraically: $$\sf\dfrac{2}{\color{blue}{b}}=\dfrac{n_C}{\color{green}{c}}\rightarrow n_C=\dfrac{2*\color{green}{c}}{\color{blue}{b}}$$ $$\sf \large 4.$$ Solve
