Answer:
- The <em>kinetic molecular theory explains the pressure exerted by gases </em>as the result of many collissions of the gas particles (atoms or molecules) with the walls of the vessel where they are contained.
- The pressure is the perpendicular force per unit area exerted by the gas particles when they hit the walls of the container.
Explanation:
As per the kinetic molecular theory, gases consist on a large number of tiny particles (atoms or molecules) in continuous rapid random motion.
The particles are so small that they are considered to have a negligible volume compared with the volume of the vessel where they are confined.
Since the number of molecules is so large, statistical approach can be applied.
The rapidly moving particles constantly collide among them and with the walls of the container. The collisions are considered elastic, which means that there is no loss of energy after the coliisions.
Applying classical (Newtonian) mechanic and the statistical approach, the kinetic theory calculates the <em>pressure exerted by gases as </em><u><em>the force exerted by the particles when they hit the walls of the container per unit of area.</em></u>
I am not the best at this, but im pretty sure its below cloud

Explanation:
standard notation is simpily just the answer.
<h2>Hello!</h2>
The answer is: C2H6
<h2>Why?</h2>
First, we need to find the empirical formula of the compound:
Looking for the relative atomic mass for each element:
Finding the number of moles for each element:
Then, we need to determinate the mole ratio by dividing each result into the smallest number:
So, the empirical formula would be CH3
We are given the molar mass of the compound is equal to 30 g/mol
We need to compare the empirical formula molecular mass and the molecular formula molar mass in order to find the number of atoms of the compound:
Empirical formula molar mass:
Molecular formula molar mass = 30.0 g/mol
So, by dividing the molecular formula molar mass by the empirical formula molar mass we have the number of atoms of the compound:
Therefore,
The molecular formula will be: (CH3)2= C2H6
Have a nice day!
Answer: metal and non- metal
Explanation: metals form cations and non-metals anions which form ionic bond.
