Question

I can't solve 8-d and 8-e.

Please check the answers if you don't mind

Make a table with three columns: HCI volume, pressure and change in pressure. Enter in the first row zero for the HCI volume, the initial pressure that you recorded after adding the water and zero for the change in pressure. What is the nearest whole number ratio for your experimentally-determined ratio? For example, if the experimental ratio is 1.75, then you would use a whole number ratio of 2 to 1. If the experimental ratio is 3.2. then you would use a whole number ratio of 3 to 1. Use the whole number ratio to balance the equation for the reaction. If your whole number ration is 2 to 1, then place a 2 next to the CO2 and a 1 next to the NaHCO3. Continue from there to balance the number of atoms on each side of the equation. Write the balanced equation here:

Explanation / Answer

Answer:

8d). It is asked to find nearest whole number ratio of number of moles of CO2 to number of moles of NaHCO3.

The number of moles of CO2 and number of NaHCO3 taken was 0.00595 mol.

So their ratio will be = 0.00595/0.00595 = 1

8e).

Balanced equation for the reaction is:

NaHCO3(s) + HCl (l) ? NaCl (aq) + H2O (l) + CO2(g)

As all atoms are equal on both sides of the equation.

Check once in 2a).There was change in pressure was at 1ml addition of HCl.
