When hydrogen nuclei are fused together to form a helium nucleus, the mass of the product is 0.7% less than the mass of the reactants. if 1 gram (1 × 10-3 kg) of protons were completely fused into helium nuclei, the mass of the helium nuclei produced would be 6.8 × 10-6 kg less than the mass of the protons. using the equation e = mc2, calculate how many joules of energy would be produced by converting 6.8 × 10-6 kg of matter into energy in this fusion reaction. use c = 3 × 108 m/s.

Explanation:

As noted, this formula states that anything that has mass contains a corresponding energy, given by its mass multiplied by the speed of light squared. Similarly, energy contains a corresponding mass given by its energy divided by the speed of light squared.

So, replacing in the formula:

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 .

i guess it’s a and b
