Question
Balance this equation.
NaHCO3(s) + heat ----> Na2CO3(s) + H2O(l) + CO2(g).
i balanced it & got: 2NaHCO3(s)+ heat -->Na2CO3(s)+ H2O(g)+CO2(g) is this right ?
Determine how many moles of CO2(g) is
produced when 7mols of NaHCO3 are consumed. how do i do this ?

The equation looks balanced to me. Your question. Use the coefficients to make conversions from moles of one material to moles of another material. For example, 2 moles NaHCO2 will produce 1 mole CO2, 1 mole H2O, and 1 mole Na2CO3. How many mols NaHCO3 will it take to produce 10 moles CO2. 10 moles CO2 x (2 moles NaHCO3/1 mole CO2) = 20 moles NaHCO3. Note how the unit CO2 cancels and leaves the unit NaHCO3 which you want to keep.
would the answer be 14 moles of CO2?
14 is correct.
balance equation
----Cl2 (g)+----KBr (aq)-----Br2 (l) +---KCl (aq)
----Cl2 (g)+----KBr (aq)-----Br2 (l) +---KCl (aq)
----Cl2 (g)+----HBr (aq)-----Br2 (1)+-----KCl (aq)
Should be 7mol/2= 3.5 mol = =
