Answer 2

The correct reaction equation is:

`3NaHCO_(3) (aq) + C_(6)H_(8)O_(7) (aq) \rightarrow 3CO_(2) (g) + 3H_(2)O (l) + Na_(3)C_(6)H_(5)O_(7) (aq)`

Answer:

b) 1 mole of water is produced for every mole of carbon dioxide produced.

Explanation: CONVERT EVERYTHING TO MOLES OR VOLUME, THEN COMPARE IT WITH THE COMPOUND'S STOICHIOMETRY IN CHEMICAL EQUATION.

a) 22.4 L of
`CO_(2)` gas is produced only when
`(22.4)/(3)` L of
`C_(6)H_(8)O_(7)` is reacted with 22.4 L of
`NaHCO_(3)`. So it is wrong.

b) Since in the chemical equation the stoichiometric coefficient of
`CO_(2)` and
`H_(2)O` are same so the number of moles or volume of each of them will be same whatever the amount of reactants taken. Therefore it is correct option.

c)
`6.02* 10^(23)` molecules is equal 1 mole of
`Na_(3)C_(6)H_(5)O_(7)` if produced then 3 moles of
`NaHCO_(3)` is required, which is not given in the option. So it is wrong.

d) 54 g of water or 3 moles of
`H_(2)O` (Molecular Weight of water is 18 g) is produced when 3 moles of
`NaHCO_(3)` is used but in this option only one mole of
`NaHCO_(3)` is given. So it is wrong.
