answer: D
Here is a list of the most common ways to speed up a chemical reaction
Increase the temperature (reactions that absorb energy)
Decrease the temperature (Reactions that release energy)
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.

Answer is: B.) Yes, if work is done, this transfer process can take place.
For example, air conditioner involves a cyclic process that transfers heat from a cold reservoir to a hot reservoir, but with use of electricity.
Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.
The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
Answer:
13.4%
Explanation:
Take the molar mass (26.98) of Al x 2 because there are 2 moles in the given compound. Divide this number by the total molar mass of the compound (401.9) this gives you .134. To get a percentage mulitply by 100 for 13.4%.
[(26.98 x 2)/401.9] x 100 =13.4
I’m not 100% sure but I think it’s C
