hodyreva [135]

Answer:

E =230.4 MJ

Explanation:

As 1 mole of electron =  6X 10^23 particles.

charge of an electron is 1.6 X 10 ^-19 C

Finding Charge:

(6X10^23 ) (2.7)(1.6X10^-19 C)

i.e. 192 K C

now  to find the energy released from electrons

V=E/q

E=V X q

i.e E = 120 V X 192 K C

E =230.4 MJ

An experiment is performed on an unknown material and produces the given heat curve. The temperature of the material is shown as
BlackZzzverrR [31]

Answer:

In the table, 1=46.7 °C, 1=165 J, 2=819 J, 3=1510 J, and 4=2830 J.

Other experiments determine that the material has a temperature of fusion of

fusion =235 °C and a temperature of vaporization of vapor=481 °C.

If the sample of material has a mass of =8.60 g, calculate the specific heat when this material is a solid, and when it is liquid, l

How does the law of conservation of energy relate to the system shown in this model
egoroff_w [7]

Answer: The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system.
