In the diagram, an activity which is happening to the temperature at Point B is that: C. The temperature is not rising because the heat is being used to break the connections between the molecules.
<h3>What is matter?</h3>
Matter can be defined as any physical object or body that has both mass and takes up space. This ultimately implies that, the mass of a physical object measures the amount of matter the object contains.
<h3>What is heat?</h3>
In Science, heat is sometimes referred to as thermal energy and it can be defined as a form of energy that is transferred from a physical object (body) to another due to a difference in temperature.
By critically observing the diagram, we can reasonably infer and logically deduce that matter has dynamic states depending on the composition of its atoms and at point B the temperature remained constant (not rising) because the quantity of heat generated is used for breaking any form of connection between the molecules.

Answer:
1st step : mix the mixture with water that way A will dissolve while B will remain insoluble.
2nd step :To get B from the solution, filter the mixture and get B
3rd step : To get A from the solution evaporate the new solution
Explanation:
Assuming 2mg of impurity B to be present
100 mg of A is present as well
<u>Method of purifying A given that B is of same solubility </u>
Dissolve the 100 mg of A with 30 mL
1st step : mix the mixture with water that way A will dissolve while B will remain insoluble.
2nd step :To get B from the solution, filter the mixture and get B
3rd step : To get A from the solution evaporate the new solution
molar concentration of AgNO₃ solution = 0.118 mole/L
Explanation:
Because we have the volume of the solution and there is no information about the density of the solution I will asume that you ask for the molar concentration.
number of moles = mass / molecular weight
number of moles of AgNO₃ = 10 / 170 = 0.0588
molar concentration = number of moles / volume (L)
molar concentration of AgNO₃ solution = 0.0588 / 0.5
molar concentration of AgNO₃ solution = 0.118 mole/L

I'm not positive, but I believe it would be one near the Rocky Mountains.
