Answer:
They both have 7 electrons in their outer shell
molar mass of methane CH4
= C + 4 H
= 12.0 + 4 x 1.008
= 12.0 + 4.032
= 16.042g/mol
7.31 x 10^25 molecules x <u> 1 mole CH4 </u> = 121.43 moles
6.02 x 10^23 CH4 molecules
121.43 moles CH4 are present.
Endothermic is a chemical reaction which absorbs energy in the form of heat
Amino acids.
Amino acids group together to form proteins. Enzymes are protein in nature. Thus the substrate is an amino acid.
