Describe the similarities and differences between the motion of particles in liquids and gases.

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

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
