Which of the following is true about nuclear fission?

Chemistry
1 answer:
solmaris [256]3 years ago
3 0

Answer:

If you add the masses of all the products after fission, they are LESS than the mass of the reactants.

Explanation:

A nuclear fission reaction is a radioactive reaction which in which a heavy nucleus spontaneously disintegrates into 2 lighter nuclei and some neutrons with a release of large amount of energy.

When nuclear fission occurs, a mass deficit between the decaying nuclei and the product occurs. It is this mass that actually yields the energy that is produced as a by product of the reaction.

2 h2o ( g) 2 h2 (g) + o2 (g) kp = 7.8 × 10-16 at 930 k. give the value of kp for this reaction, if it is written as: 1/2o2 (g) +
trapecia [35]
When multiplying by a constant, raise Kp to the power of that constant.

When the reaction is reversed, it gives the inverse of Kp.

Kp^(-1/2) = (7.8 x 10^-16)^(-1/2) = 3.6 x 10^7

Three substances A, B, and C melt at 00C,500C and -1500C
Drupady [299]
Answer:

That information is better presented and analyzed in a table.

This table shows you all the information and the answers:


Substance         melting point   boiling point    room temperature    conclusion
                                    °C                  °C                      °C                    (state)


A                                  0                    100                    25                    liquid

B                                  50                  200                    25                    solid
C                               -150                   10                     25                    gas

Explanation:

1) Substance A at 25° is above the melting point and below the boiling point, then it is liquid (just like water)


2) Substance B at 25°C is below the melting point, so it is solid.

3) Substance C at 25°C is above the boiling point, so it is gas.
