Question

How much Is Calcium oxide formed when 82g of calcium nitrate is heated? Also, find the volume of nitrogen dioxide evolved :

2Ca(NO3)2 → 2CaO+4NO2+O2

(Ca = 40 , N = 14,O = 16)

Solution

2Ca(Na3)2 → 2CaO + 4NO2 ↑ + O2

At STP, 1 mole of any gas contains 22.4L

Since, 4 moles of NO are produced,

∴ volume of nitrogen dioxide obtained = 4 x 22.4 = 89.6 L

2 moles of Ca(NO3)2 produces 2 moles of CaO

328 g Ca(NO3)2 produces = 112 g CaO

1 g Ca(NO3)2 will produce = `112/328` g CaO

= 0.34 g CaO

Hence, 82 g of Ca(NO3)2 will produce = 82 x 0.34 = 27.88 g of CaO.

  Is there an error in this question or solution?
