According to the graph in figure 3 about how much more energy is released by burning 1 g of natural gas compared to burn in 1 g of wood

Answer ozone (o3) is made of three atoms of oxygen, it is a molecule;

Answerionic bond imfs are stronger than covalent;

Moles of co₂ = 2.35/44 = 0.0534 mole.from ideal gas equation pv=nrt,  t = 18+273k = 291 kelvin.∴px5 = 0.0534x0.0821x291∴p = 0.0534x0.0821x291/5 = 0.2551 atm.now, 1 atm = 760 mm of hg  ∴ 0.02551 atm = 0.02551 x 760 = 19.38 mm of hg
