Mass would crystallize out : 24 g
<h3>Further explanation
</h3>
Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
-
1. Temperature:
-
2. Surface area:
-
3. Solvent type:
-
4. Stirring process:
We can use solubility graph to solve this.
solubility KClO₃ at 90°C=52 g
solubilty KCl₃ at 60°C= 28 g
Mass would crystallize out = 52 - 28 =24 g

tantalum
i hope this helps<33 :)))))
Answer: orderly arrangement of particles
Explanation:
In a crystaline solid, the particles that compose the solid are arranged or packed in an orderly manner to form a three dimensional crystal lattice with a defined structure. Sodium chloride is a crystaline solid.
In an amorphous solid, the particles that compose the solid aren't arranged in an orderly manner hence the solid tends to be brittle, e.g glass
Answer:
The total heat required is 3.4 kJ
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. So, the amount of heat a body receives or transmits is determined by:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case you know;
- c= 4

- m= 10 g
- ΔT= Tfinal - Tinitial= 10 C - 0 C= 10 C
Replacing:

Solving:
<em>Q1= 400 J</em>
On the other hand, you must determine the heat required to convert 0 ∘ C of ice to 0 ∘ C of liquid water by:
Q2=m*heat of fusion
Q2=10 g* 300 
<em>Q2= 3,000 J</em>
The total heat required is:
Q= Q1 + Q2= 400 J + 3,000 J
Q= 3,400 J= 3.4 kJ (1 kJ= 1,000 J)
<u><em>The total heat required is 3.4 kJ</em></u>
