प्रश्न
8.2 grams of calcium nitrate is decomposed by heating according to the equation
\[\ce{2Ca(NO3)2 -> 2CaO + 4NO2 + O2}\]
Calculate the following:
Volume of nitrogen dioxide obtained at STP
[Atomic weights: Ca − 40, N − 14, 0 − 16]
बेरीज
उत्तर
328 g of calcium nitrate liberated
4 × 22.4 lit of NO2
8.2 g of calcium nitrate liberated
`(4 × 22.4 × 8.2)/328`
= 2.24 lit of NO2
