Answer:
This question sadly does not make much sense, please rephrase it.
Answer:
CH3OH and NADH
Explanation:
The given chemical reaction is an redox reaction in which reduction and oxidation take place.
In the process of oxidation: electrons are loss while in the process of reduction: electrons are gained.
In the given redox reaction: CH3OH + NAD --> CH2O + NADH
NAD is reduced to NADH as NADH gains one hydrogen electron while CH3OH (methanol) is oxidized to CH2O (methanal) by losing electrons.
So, CH3OH (methanol) and NADH are the reduced forms while NAD and CH2O (methanal) are oxidized forms.

Chemical changes only happen when the object changes form. Color is a physical property because you're not changing the object that you have, compressibility is also a physical property because you still have the same substance before and sfter, malleability again is another physical. Heat of combustion is physical, when you burn things it changes the substance. :)
Answer:
D. 5.6 g/cm^3
Explanation:
On the average seismic velocity increases with increase in depth due higher the pressure and more compaction
sand and shales in the Niger Delta Basin density–velocity relationship is
P = 0.31×V^0.25
A derivation of the original Gardner equation to calculate the average densities for sands and shales in wells.
ρ = α ×V^β
where
ρ = bulk density in g/cm3,
V = P-wave velocity,
α = 0.31 for V (m/s) and 0.23 for V(ft/s) and
β = 0.25.
Such that
ρ = 0.31 ×V^0.25
So the fastest seismic velocity will be in the densest material which is D. 5.6 g/cm3
