Sodium bicarbonate breaks down on heating as follows:
`2NaHCO_(3) to Na_(2)CO_(3)+H_(2)O+CO_(2)`
(Atomic mass of Na=23, H=1, C=12, O=16)
(i) How many moles of `NaHCO_(3)` are there in the equations?
(ii) What is the mass of `CO_(2)` produced in the equation?
(iii) How many moles of water molecules are produced in the equations?
(iv) What is the mass of `NaHCO_(3)` used in this equations?
(v) What is thee volume occupied by `CO_(2)` in this equations?

Explanation

(i) 2 moles.
(ii) 44g.
(iii) 1 mole.
(iv) =2[23+1+12+3(16)]
=2[84]
=168g
(v) 22.4 lit.
