The average molecular weight of the mixture can be calculated using this formula:
MWav = x1MW1 + x2MW2
Where x is the mass fraction of the components of the mixture, in this case, copper (63.546 g/mol) and zinc (<span>65.38 g/mol).
</span>
x1 = 7.36 / (7.36+0.51)=0.935
x2 = 0.51 / (7.36+0.51)=0.065
So,
MWav = 0.935(63.546) + 0.065(65.38) = 63.665 g/mol
Answer: lone pair of electrons
Explanation: A bonding electron domain is a pair of electrons shared between two atoms and a nonbonding is a lone pair of electrons
The best and most correct answer among the choices provided by your question is the fourth choice or letter D which is "Alcoholic fermentation."
Ethanol fermentation<span>, also called alcoholic </span>fermentation<span>, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as a side-effect.</span>
