Question

When Ca(NO3)2 is heated, it gives CaO, NO2 and O2. The correct number of moles of Ca(NO3)2, CaO, NO2 and O2 are present in the reaction are

Answer 1

Answer:

So, 2 moles of Calcium Nitrate i.e., 328 g ofCalcium Nitrate produces 5moles of gaseous products. 2 moles of Calcium Nitrate produces 4 Moles of Nitrogen Dioxide, which is 4*22.4L of Nitrogen Dioxide. So, 2 moles of Calcium Nitrate produces 4*22.4 =L ofNitrogen Dioxide.

Answer 2

The number of moles of $Ca(NO_3)_2, CaO, NO_2, O_2$ are 2,2,4,1.

• Calcium nitrate on heating produces calcium oxide, nitrogen dioxide gas and oxygen gas.
• The reaction is-
• $2Ca(NO_3)_2\rightarrow 2CaO+4NO_2+O_2$
• When two moles of calcium nitrate is heated two moles of calcium oxide, four moles of nitrogen dioxide gas and Ine mole of oxygen gas are formed.
• Thus the number of moles of $Ca(NO_3)_2, CaO, NO_2, O_2$ are 2,2,4,1.
