In the kinetic theory, the particles in a gas A. move independently of each other.
B. have attractive and repulsive forces.
C. move slowly.
D. are relatively close together.

Im pretty sure its B

Sorry if Im wrong

Explanation:

Have a wonderful day!!!<3

The only answer that could apply to a gas is A

Explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

i don,t know so just answer mine
