Answer:
b. 101.02°C
Explanation:
The elevation of boiling point in a solvent due the addition of a solute is a colligative property called <em>Boiling point Elevation. </em>The formula is:
ΔT = Kb*m*i
<em>Where ΔT is change in boiling point</em>
<em>Kb is boilinig point elevation constant = 0.512°C/m for water</em>
<em>m is molality of the solution = 0.50m</em>
<em>And i is Van't Hoff Factor (4 for the Al(NO₃)₃ because its disolution produce 4 ions)</em>
<em />
Replacing:
ΔT = 0.512°C/m*0.50m*4
ΔT = 1.02°C
As the boiling point of pure water is 100°C and the increasing is of 1.02°C, boiling point of the solution is:
101.02°C
Right option is:
<h3>b. 101.02°C</h3>

Answer:
Any terrestrial planet has highest temperature at its core and least temperature at its crust.
HOPE THIS HELPS! <3
Explanation:
Considering the composition of earth, there are three main layers whose composition and temperature. Here as follows-
<em>a) Inner Core – The inner core is made up of iron and nickel and has a temperature of 7200 degree Celsius.
</em>
<em>
</em>
<em>b) Molten Outer core – It is also made up of iron and nickel and has a temperature of 4300 degree Celsius.
</em>
<em>
</em>
<em>c) Inner mantle – It is semi rigid and made up of silicon, oxygen, magnesium, iron, aluminum, and calcium and has a temperature of 3700 degree Celsius
</em>
<em>
</em>
<em>d) Crust – It is made up of water, basalt and granite and has a temperature of 0 degree Celsius
</em>
<em />
Looking at the composition and the temperature of the different layers, it shows that any terrestrial planet has highest temp in the core and the least at its crust!

Daughter cells?
It might be called haploid daughter cells too.
