Answer: A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products
Answer: C. Al (aluminum)
Explanation: it has 3 valence electrons :)
On eof the forces is inertia. This can happen when you move your furniture to clean under them. When you move an object in a straight line without chanign its composition (e.g moving a chair or a table from one side to the other) you are working with inertia. The secon force is friction. It s present when you clean a surface by rubbing it with a tool like a damp cloth or a mop.
Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

The pressure of the xenon gas will increase if the number of moles increases because as more molecules are in the container, the molecules hit the container of the wall more often (option C).
<h3>What is an ideal gas?</h3>
Ideal gas is a hypothetical gas, whose molecules exhibit no interaction, and undergo elastic collision with each other and with the walls of the container.
According to this question, a 1.81 mol sample of Xenon gas is confined in a 42.6 liter container at 14.1 °C. If the amount of gas is increased to 2.72 mol, holding the volume and temperature constant, the pressure will increase.
An increase in the number of gas molecules, while container volume stays constant causes the pressure to increase due to the fact that the molecules will collide more with the walls of the container.
