The total annual energy consumption in the U. S.A. is 1.00 x 10 20
joules. If you were capable of converting mass to energy with 100% efficiency, how much mass, in kg, would you need to produce an energy E = 1 x 10
20
joules?

your parents i think this could be it

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

i would say b

explanation:

but i think i would need more information than that
