Answer:
The atomic mass of Si-30 is 29.955 amu
Explanation:
Step 1: Data given
Si-28 has an atomic mass of 27.9769 amu and a natural abundance of 92.2 %
Si-29 has an atomic mass of 28.9765 amu and a natural abundance of 4.67%
The atomic mass of Si is 28.0855 amu
Step 2: Calculate natural abundance of Si-30
100% - 92.2 % - 4.67% = 3.13 %
0.922 * 27.9769 + 0.0467 * 28.9765 + 0.0313* X = 28.0855
27.14790435 + 0.0313X = 28.0855
0.0313X = 0.93760
X = 29.955 amu
The atomic mass of Si-30 is 29.955 amu

When NAD becomes NADH, it is being reduced and gaining chemical energy.
Nicotinamide adenine dinucleotide (NAD), a coenzyme, can exist in two forms, NAD⁺ (oxidized) and NADH (reduced form).
Electrons and protons released in catabolism reactions are attached to NAD⁺. The conversion of NAD⁺ to NADH is important reaction for production of ATP during the cellular respiration.
Reduction is lowering oxidation number because element, ion or compound gain electrons.
Chemical equation for reaction of reduction of NAD⁺ (see picture below):
NAD⁺ + 2e⁻ + H⁺ → NADH
Nicotinamide adenine dinucleotide (NAD) is made of two nucleosides joined by pyrophosphate.
