carbon atom can form four covalent bonds.
The subsurface process is composed of a series of complex geologic processes, hence, it's modeling can only best be undertaken by a team of professionals from each of the relevant majors.
Modeling the earth's interior requires the expertise of geophysicsts in using geophysical techniques to obtain subsurface readings at various depths, seismologist obtains and interpretes arrival <em>times of seismic waves</em>, petrophysicst evaluates subsurface properties using log data and so on.
Therefore, the complexity of the subsurface makes it imperative that professionals collaborate in other to come up with an accurate model.

First step: calculate the number of moles of sodium reacted
moles=mass/molar mass
31.5g/23g/mol =1.37moles
from the reaction above the reacting ratio of Na to H2 is 2:1 therefore moles of H2 is 1.37/2=0.685
At STP 1 mole = 22.4L what about 0.685 moles
22.4 x0.685=15.344L
Cytosine guanine thymine adenine
Answer:
radio waves
Explanation:
On the far left of the diagram are radio waves, which include microwaves. They have the longest wavelengths and lowest frequencies of all electromagnetic waves. They also have the least amount of energy.
