The mathematical expression for heat capacity at constant pressure is given as:
(1)
where, Q = heat capacity
= molar heat capacity at constant pressure
= change in temperature
n = number of moles
Therefore,
= 
= 
Number of moles =
=
= 0.186 mole
Put the values in formula (1)
(conversion of degree Celsius into kelvin)
=
= 6.32 J /mol K
Hence, molar heat capacity of benzene at constant pressure = 
Answer:
Product D contains 30 J
Explanation:
We know energy does not destroy or create, it only transforms. So, at the right side of the equation we have the energy of the reactant A and the energy of the reactant B, as a sum, and, as a result we have to get the same energy plus the energy absorbed by the reaction.
So, we have,
Ea+Eb = Eabsorbed+Ec+Ed
Ed = Ea+Eb-Eabsorbed-Ec
Ed = 85.1 J + 87.9 J - 104.3 J - 38.7 J
Ed = 30 J

4. Halley urged newton to write Principia mathematica and when the Royal society declined to pay the cost of publishing Halley paid for it out of his own pocket
5.Through using a telescope Galileo Galilei was able to prove the theories of sciences Isaac newton
6. He believe that the speed of an object motion is proportional to the force being applied and inversely proportional to the density of the medium he reason that the object moving in a void would move in definitely fast and thus any and all objects
7. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Answer: The mass is 348.8g
Explanation:
We begin by using Avogadro's number to convert the number of molecules of Sodium Hydroxide to moles.
6.02 x 10∧23 molecules of NaOH -------> 1 mole of NaOH
∴ 5.25 x 10∧24 molecules of NaOH -------> 1/ 6.02 x 10∧23 x 5.25 x 10∧24 =
8.72moles.
Having found the number of moles, we then move from moles to gram by using the molar mass of NaOH (i.e the mass of 1 mole of NaOH).
1 mole of NaOH is equivalent to 40g (Molar Mass)
8.72 moles of NaOH would be equivalent to; 40/ 1 x 8.72 = 348.8g
The mass in 5.25 x 10∧24molecules of NaOH is 348.8g
