You may recall that the products of the complete combustion of a
hydrocarbon are water vapor and carbon dioxide gas. write the balanced
equation showing the combustion of methane. do not forget to include the
states of matter of the reactants and the products. hint: methane is a gas at
standard temperature and pressure.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
