How much energy in (kj/mol) is produced in the following fission reaction of plutonium-239? 23994pu+10n→14656ba+9138sr+310n the masses are as follows: 239.05216 u for 239pu, 145.93022 u for 146ba, 90.91020 u for 91sr, and 1.00867 u for 10n. express the energy to three significant figures and include the appropriate units.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
