The answer is
A + oxygen ➡ energy
The sand is the residue and a mixture of salt dissolved in water is the filtrate
Yes, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample.
<h3>What is Average Kinetic Energy ?</h3>
The average kinetic energy of a gas molecule is defined as the product of half of the mass of each gas molecule and the square of the RMS speed.
The average kinetic energy equation is independent of Molar mass.
It's only a function of temperature.
So if they're at the same temperature they will have the same average kinetic energy.
Therefore, the atoms in the helium sample have the same average kinetic energy as the atoms in the argon sample

Answer:
P2 = 226.6 kPa (Approx)
Explanation:
Given:
Temperature t = 25ºC
Old volume v1 = 145 ml
Old pressure p1 = 125 KPa
New volume v2 = 80 ml
Find:
New pressure p2
Computation:
p1v1 = p2v2
125 x 145 = P2 x 80
P2 = 226.6 kPa (Approx)
