1 answer:
The heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
<h3>What is heat?</h3>Heat is the transportation of energy to or from a thermodynamic system.
By the formula of heat
Where n = moles
Delta Hrxn is molar heat
q = heat
Putting the values in the equation
Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.

The answers to the given questions on the survey of students by the use of a Venn Diagram are;
A) Venn diagram attached
B) 57 Students
C) 811 Students
D) 785 Students
E) 67 Students
<h3>Understanding Venn Diagrams</h3>
We are given;
- Total number of Students = 1358
- Number of Students that plan to get a new job = 1194
- Number of Students that plan to attend graduate school = 306
- Number of Students that plan to buy a new car = 547
- Number of Students that plan to do all three things = 46
- Number of Students that plan to only attend graduate school = 28
- Number of Students that plan to get a job and buy a new car, but not attend graduate school = 432
- Number of Students that plan to get a new job and attend graduate school = 221
A) I have drawn a Venn Diagram to depict this given numbers of students and I have attached it.
B) From the venn diagram, we can see that the number of people that plan to attend graduate school and buy a new car, but not get a new job = 57
C) From the Venn diagram, we can calculate the number of students that do not plan to buy a new car is;
541 + 175 + 28 + 67 = 811
D) From the venn diagram, we can calculate the number of students plan to get a new job or buy a new car as;
541 + 175 + 12 + 57 = 785
E) From the venn diagram, we can see that the number of students that do not plan to get a new job, attend graduate school, nor buy a new car is; 67
