Coal is made of carbon and also has more elements like hydrogen, oxygen, sulfur and nitrogen.
Coal starts as plant matter at the bottom of ocean/water. Eventually it is covered and buried by sediments where over a while, metamorphosis (a change in form) happens.
Coal is also one of the biggest, if not the largest, source of energy for the making of electricity.

The critical point of carbon dioxide is 304 k and 73 atm. under which conditions is carbon dioxide a liquid? i. 303 k and 73 atm

Sergeeva-Olga [200]

Answer is: a) I only.
Above critical temperature of CO₂, a gas cannot be liquefied no matter how much pressure is applied. Temperature and pressure above its critical point is called supercritical fluid and this is intermediate between gaseous and liquid states.

All three of the phosphorus-fluorine single bonds in pf3 are polar. in which direction should the polarity arrows point?

nydimaria [60]

One of the causes of polarity is the unequal forces of the dipole forces due to differences in electronegativity. The more electronegative molecule tend to attract electrons, hence the polarity arrows point towards it. The electronegativity of Phosphorus and Fluorine is 2.19 and 3.98, respectively. Thus, it points outward towards the fluorine atoms.

In a certain industrial process involving a heterogeneous catalyst, the volume of the catalyst (in the shape of a sphere) is 10.

olga nikolaevna [1]

Answer:

a. The second run will be faster.

d. The second run has twice the surface area.

Explanation:

The rate of a reaction is proportional to the surface area of a catalyst. Given the volume (V) of a sphere, we can find its surface area (A) using the following expression.

$A=\pi ^{1/3} (6V)^{2/3}$
