ΔT= T (solvet freezing point)-T (solution) =T(water freezing point)-T(solution)
ΔT =0⁰C - T(solution)
ΔT=

molality =(number mol solute)/kg solvent = 0.31mol/0.175 kg =(0.31/0.175)m
K(f water)=1.86⁰C/m
ΔT=1.86⁰C/m*(0.31/0.175)m=3.29⁰C
T(solution) =0⁰C - 3.29⁰C =3.29⁰C
Answer:
I think the answer is 50.546
Answer:
D
Explanation:
The picture depicts the data of the chemical, explaining that as the temperature rises, the chemical reaction rate would increase as well.
Burning a magnesium ribbon in the air is an addition reaction while heating potassium manganate 7 is a decomposition reaction.
<h3>Addition and decomposition reactions</h3>
Magnesium burns in air to produce magnesium oxide as follows:

Potassium manganate 7 burns to produce multiple products as follows:

Thus, the MgO will be heavier than Mg. On the other hand,
will be less heavy than
.
