Na-23 has 12 neutrons. What is it’s atomic number?
erastovalidia [21]

Answer:

11

Explanation:

The atomic number = number of protons. The mass number (23) = sum of number of neutrons and protons. Since you know the mass number is 23 and it has 12 neutrons, 23-12 gives you 11 protons, so its atomic number is 11.

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
