Question

When Ca(NO3)2 is heated, it gives CaO, NO2(g)

and O2 (g) The correct number of moles of

Ca(NO3)2 , CaO, NO2 (g) and O2(g) are present

in the reaction are respectively​

Answer 1

Answer:

2 moles of Ca(NO₃)₂ releases 2 moles of CaO , 4 moles of NO₂ and 1 mole of O₂ .

Explanation:

We will do balancing here and the coefficients so received along with the compounds / elements represent the number of moles .

Answer 2

Answer:

2,2,4,1

Explanation:

Try to balance i, you'll get
(2)Ca(NO3)2 = (2)CaO+(4)NO2+(1)O2

Moles are basically number of molecules so the number of molecules of reactants and products are the moles
