ANS: C = 85.63 %; H = 14.37 %
C = 2 x 12.01 u = 24.02 u
H = 4 x 1.008 u = 4.032 u
TOTAL = 28.052 u
% C = (24.02/28.052) x 100 % = 85.63 %
% H = (4.032/28.052) x 100 % = 14.37 %
No <span>it can not the absolute energy states of the reactants (E1) and products (E2) be measured in a chemical reaction
hope it helps</span>

Answer:
0.25 mole of NO2 contains 0.25 mole 'N'
one mole contains 6.023 x 10 ^23 atoms
0.25 mole II------------------------------>?
= 0.25 x 6.023 x10^23 = 1.5 x 10^23 atoms
