1. Which of the following shows the process of freezing?' A. candle wax cooling on the table
B. pouring cola over ice
C. heating a cup of water
D. particles are speeding-up and colliding more

A. candle wax cooling on the table

Explanation:

Candle wax cooling on a table is an example of freezing because the atoms in the candle wax start to slow down as the wax cools. This is considered "freezing" because the slower an atom is vibrating then the colder it is and of course the faster an atom is vibrating then the hotter it is! :)

a) the particles of the chair are strongly held together.

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
