Answer:
speed
Explanation:
Speed is the rate at which something moves. The speed of light is faster than the speed of sound.
The way to know this is by using the next procedure:
<span>n = c x v
0.665 = 1.15 x v
v = 0.578L = 578mL QED
This is going to help you indeed. Hope its good for you

<span>The correct answer is (C) 0.2 mole MgCl2.
according to Van't Hoff factor rule which is the ratio between the actual
concentration of the particles produced when the substance dissolved and
the concentration of the substance as measured from its mass, so here 0.2
mole MgCl2 is the higher van't Hoff factor as it has more ions than other
choices and the higher concentration.
and when the boiling point formula is delta Tb = Kb * m * i.
when delta Tb is the change in boiling point.
and Kb is molal boiling point constant
and m is the molality of the solution
and i is Van't Hoff factor.
so we can see the relationship between i and delta Tb, the greater Van't Hoff factor the higher the boiling point. so 0.2 MgCl2 is the higher boiling point as it is the greater van't Hoff factor.</span>
Answer:
When naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. ” Mono-” indicates one, “Di-” indicates two, “Tri-” is three, “Tetra-” is four, “Penta-” is five, and “Hexa-” is six, “Hepta-” is seven, “Octo-” is eight, “Nona-” is nine, and “Deca-” is ten.
Methane (CH4) is an organic compound an a hydrocarbon. The statement above is a fact and therefore the answer to the question is letter "A" or "A.True". I hope this helps you on your assignment.
