1.	Sodium bi carbonate breaks down on heating: 2NaHCO_(3)rarr Na_(2)CO_(3)+H_(2)O+CO_(2) ("Atomic mass of Na"=23, C=12, H=1, O=16) (i) How many moles of sodium bi carbonate are there in this equation? (ii) What is the mass of sodium bicarbonate used in this equation? (iii) How many moles of carbon dioxide are there in this equation?
Answer» Solution :`2NaHCO_(3)overset(Delta)rarr Na_(2)CO_(3)+H_(2)O+CO_(2)uarr` (ii) 2 moles of `NaHCO_(3)` (sodium bicarbonate) are there in the above equation. (ii) Mass of sodium bicarbonate in this equationi is mass of 2 moles of `NaHCO_(3)`. `{:("Atomic mass of 1(NA) "1xx23,=, 23g),("Atomic mass of 1(H)"=1xx1,=,1G),("Atomic mass of 1(C)"=1xx12,=,12G),("Atomic mass of 3(O)"=3xx16,=,48),(,,""ulbar("84g")):}` Mass of 1 MOLE of `NaHCO_(3)=84g` `therefore"Mass of 2 moles of "NaHCO_(3)=84xx2=168g` (iii) Number of moles of `Co_(2)` in this equation = 1 mole
