In a nuclear reaction, the energy released is equal to 8.1 x 1016 joules. calculate the mass lost in this reaction. (1 j = 1 kg m2/s2) and the speed of light = 3.00 × 10^8 m/s ]

answer

7.2 x 1032 kg

2.7 x 108 kg

9.0 x 10-1 kg

7.2 x 10-16 kg

Answer : The mass lost in this reaction will be,

Explanation :

According to the Einstein equation, the energy is equal to the product of mass and the square of the speed of light.

The mathematical expression is :

where,

E = energy  released =

c = speed of light =

m = mass lost = ?

Now put all the given values in the above formula, we get the mass lost in the reaction.

Therefore, the mass lost in this reaction will be,

a is the answer to this question

explanation:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
