1. We're going to start by recording the mass of your sample of sodium bicarbonate before heating begins. Select trial 6. Measure the mass of the sodium bicarbonate powder before heating begins. 7.14 grams Submit Answer unlimited submissions remaining Comments: Score: 1/1 Yes, that's correct. 7. The molar mass of C is 22.99 g/mol and for C is it 12.01 g/mol. You just calculated that there would be 0.085 mols of Na and 0.085 mols of C. Calculate total mass of the sodium and carbon produced in this case. Hide Hint Hint: For this reaction there are two solids. Na and C. You'll need to calculate the mass of each of these and add them to find the total mass of the remaining solids. 1 8 Submit Answer unlimited submissions remaining Heads Up!

Last one! let's make a prediction for possible reaction #4: - NaHCO, (5) -- Na.co, (s) + --CO, (e) + --H,0 () If this reaction occurs the solid product is sodium carbonate. You previously calculated that you are starting with 0.08499331183581864 moles of NaHCO,. Calculate how many moles of sodium carbonate would we expect if this reaction is occurring.
