Suppose that a white dwarf is gaining mass through accretion in a binary system. what happens if the mass someday reaches the 1.4 solar mass limit? suppose that a white dwarf is gaining mass through accretion in a binary system. what happens if the mass someday reaches the 1.4 solar mass limit? the white dwarf will collapse to become a black hole. the white dwarf will undergo a nova explosion. the white dwarf will collapse in size, becoming a neutron star. the white dwarf will explode completely as a white dwarf supernova.

The white dwarf will explode completely as a white dwarf supernova.

Explanation:

When a white dwarf gains mass to the Chandrasekhar limit of 1.44 solar masses, it would begin to collapse and, in a few seconds, the matter in the white dwarf will undergo nuclear fusion, and will become in a supernova.  

Only when the core of the white dwarf is composed of neon, magnesium, and oxygen, the gaining mass to 1.44 solar mass, will result in a neutron star.      

Therefore, the answer is the white dwarf will explode completely as a white dwarf supernova.              

I hope it helps you!                

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

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.
