To solve this question, think about which one of these options is a DIRECT effect of sea levels rising.
Choice A: If sea levels rise, they would start to cover up land that's at sea level, areas like beaches or coastal cities for example.
Choice B: Fossil fuels cause global warming. This is about the effects of global warming, not the causes.
Choice C: Not relevant. It doesn't mention alternative energy at all in this.
Choice D: Again, effects, not causes (see Choice B explanation).
The correct answer is... CHOICE A
The quantity of carbon tetrachloride, CCl₄ she will use to make her conversion is molar mass
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
<h3>How to determine the mole of CCl₄</h3>
- Mass of CCl₄ = 30 g
- Molar mass of CCl₄ = 12 + (35.5×4) = 154 g/mol
- Mole of CCl₄ =?
Mole = mass / molar mass
Mole of CCl₄ = 150 / 154
Mole of CCl₄ = 0.974 mole
Thus, we can see that the molar mass of CCl₄ is needed to obtain the number of mole.

Answer:
ork out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V).
If you have U, A and T, use V = U + AT.
If you have S, U and T, use V = 2(S/T) - U.
If you have S, U and A, use V = SQRT(U2 + 2AS)
Since there is more energy added as heat rises, the particles disperse and have larger movements.
