It would be 335 J and of energy is released
Answer:
![E=1.48x10^4J](https://tex.z-dn.net/?f=E%3D1.48x10%5E4J)
Explanation:
Hello!
In this case, since the energy implied in a heating process is computed by using the following equation:
![E=mC(T_f-T_i)](https://tex.z-dn.net/?f=E%3DmC%28T_f-T_i%29)
Whereas m is the mass, C the specific heat and T the temperature. In such a way, by plugging in the given mass, specific heat and temperatures, we obtain the following energy:
![E=187.0g*4.703\frac{J}{g\°C} (52.9\°C-36.1\°C)\\\\E=1.48x10^4J](https://tex.z-dn.net/?f=E%3D187.0g%2A4.703%5Cfrac%7BJ%7D%7Bg%5C%C2%B0C%7D%20%2852.9%5C%C2%B0C-36.1%5C%C2%B0C%29%5C%5C%5C%5CE%3D1.48x10%5E4J)
Considering that the specific heat can by used by unit of °C or K because their difference is equivalent.

Answer:</u></h2>
n = 0.0989 moles
<h2><u>
Explanation:</u></h2>
n = PV / RT
P = 2.09atm
V = 1.13L
R = 0.08206
T = 291K
Plug the numbers in the equation.
n = (2.09atm)(1.13L) / (0.08206)(291K)
n = 0.0989 moles
