Nuclear reactions produce huge amounts of energy by transforming tiny amounts of matter..true or false

True.

In fact, the energy produced by nuclear reactions can be calculated using Einstein's equivalence between mass and energy:

where m is the amount of mass converted into energy in the reaction, while c is the speed of light.

Since is really a huge number (), from the formula we see that even a tiny amount of mass m is able to produce a huge amount of energy, E.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
