The answer would be C) it is always the same as it was before the collision
It is true
I’ve done this before
There are 54 electrons, 54 protons, and 78 neutrons in an atom of 132 Xe.54.
Xenon is a chemical element with the symbol Xe and atomic number 54. It is a colourless, dense, odourless noble gas found in Earth's atmosphere in trace amounts.
Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized.
Solid xenon changes from face-centred cubic (fcc) to hexagonal close packed (hcp) crystal phase under pressure and begins to turn metallic at about 140 GPa, with no noticeable volume change in the hcp phase. It is completely metallic at 155 GPa.
When metallized, xenon appears sky blue because it absorbs red light and transmits other visible frequencies. Such behaviour is unusual for a metal and is explained by the relatively small width of the electron bands in that state.

Answer:
4.86 moles of HCl
Explanation:
1. First write the balanced chemical equations involved in the process:
2. Calculate what amount of 
is formed in the first reaction.
As the yield of each reaction is 90.0%, the amount of produced is the following:
3. Calculate the amount of HCl produced.
The total amount of HCl produced with a 90.0% yield is:
The mass of Al metal that releases 2.4 L of hydrogen gas at STP is calculated as below
AT STP 1 mole =22.4 l
what about 22.4l =? moles
(22.4 L x 1 mole) /22.4 L= 2mole
write the reacing reaction
2Al+ 6 HCL = 2AlCl3 + 3H2
by use of mole ratio between Al to H2 which is 2 : 3 the mole Al = 1 x2/3 = 0.667 moles
mass =moles x molar mass
=0.667 mole x27 g/mol= 18 grams
