In physical science lab, ben and jerry added small prices of magnesium to hydrochloride acid. Do you notice that bubbles formed, the test you've got hot, and magnesium disappeared. What is the sign of a chemical reaction has taken place in this experiment? A. Odor B. Gas is produced C. Magnesium disappeared D. Decrease in temperature

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

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.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
