Question 5
Stolb23 [73]

Answer:

There are 17.64% students received B+ grades.

Explanation:

It is given that,

Total number of students in chemistry class is 17

We need to find the percentage received by B+.

Number of students having B+ grades are 3 (from graph)

Required percentage = P=\dfrac{3}{17}\times 100=17.64\%

So, there are 17.64% students received B+ grades.

When 0.7521 g of benzoic acid was burned in a calorimeter, a temperature rise of 3.60°C was observed. What is the heat capacity
Annette [7]
Answer : S=1.34 KJ

The complete question is -

<span>When 0.7521 g of benzoic was burned in a calorimeter containing 1000 g of water, a temperature rise of 3.60C was observed. What is the heat capacity of the bomb calorimeter, excluding water? The specific heat of water is 4.184 J/g-C and the heat of combustion of benzoic acid is 26.42 kJ/g. 
</span>
On using the formula of Q_{rxn} = mSt, where m is mass of benzoic acid and S is specific heat and t is temperature, we ignore S at this stage.

on solving we get,  Q_{rxn} = 0.7521 X 26.42 = 19.870 KJ

We know, Q_{rxn} =Q_{calorimeter} + Q_{water}

Sp. heat of water is 4.184 J,

Here Q_{water} = 1000 X 4.184 X 3.6 = 15062.4 J

on multiplying Q_{rxn} X 1000 to convert into J = <span>19870.42 J

on substituting the values we get, </span>19870.482 = 15062.4 + Q_{calorimeter}, 
hence, Q_{calorimeter}= <span>4808.082,

</span>Substituting in  Q_{rxn} , we get, 4808.082=St ...(ignoring mass as we changed it to J)

t = 3.6, hence we get, S=1335 J/C on dividing by 1000 we get, S=1.34 KJ

Seriously what do i put in the x and y table im stuck and need to move to the next assignment
dem82 [27]

Remember the relationship

  • P is indirectly proportional to V

So

The pairs are

  • (2,4)
  • (1,8)
  • (4,2)
  • (12,2/3)
  • (2/3,12)

And so on
