Question

a
a) When carbon dioxide is passed over red hot carbon
carbon monoxide is
according
equation :
noxide at STP
CO2 + C -2CO
What volume of carbon monoxide
obtained from 3 g of carbon ?
​

Answer 1

Answer:

11.5 L

Explanation:

12 g c form CO= 2x 22.4L

1 g C form CO= 2X22.4/12

3 g C form CO= (2x22.4/12)x 3= 11.2 L

Answer 2

Answer:

Calcium nitrate decomposed on heating according to the equation: 2 Ca(NO3)2 - 2CaO + 4NO2 + O2 The molecular mass of calcium nitrate is 164 u. ... the volume of nitrogen dioxide (NO2) obtained at S.T.P. a the weight of calcium oxide obtained when 16.4 g of calcium nitrate is heated to constant weight.
