Which of the following is true about nuclear fission? hurry
question 2 options:
if you add the masses of all the products after fission, they are greater than the mass of the reactants.
if you add the masses of all the products after fission, they are the same as the mass of the reactants.
if you add the masses of all the products after fission, they are less than the mass of the reactants.
the mass of the products is 100 times greater than the original nucleus.

Option 3 =  i.e. If you add the masses of all the products after fission, they are LESS than the mass of the reactants

Explanation:

Nuclear fission:  Is the process in which the nucleus of radioactive element with higher mass undergoes fission and get into fragment of smaller mass with release of high energy.

The products of the nuclear fission are the fragment of smaller nuclei.

For example, larger nucleus that of uranium split into two small nuclei along with some neutrons, energy and gamma rays.

The mass of the original atom always more than  the sum of the atomic masses of the atoms produce by fission. The reason is neutrons and kinetic energy lost, and upon cooling we get product masses less than original.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

i wish i could but this one is weird give me abc and i can solve it.
