How Do You Know Whether an Object Has Potential
timofeeve [1]

The object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

<h3>Why do i think this one has potential energy?</h3>

Potential energy is a type of mechanical energy in which there is a type of stored energy that can be transformed into another type of energy. This energy is given by the <u>location of the body</u> with respect to a force field.

I selected the image of the skateboard at the top of the ramp since going up there uses kinetic energy and when it is on top of the ramp, waiting to go down, this kinetic energy is stored in potential energy that is ready to be released. The higher the height at which it is launched, <u>the more its potential energy will be</u>.

Therefore, we can confirm that the object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

Why is calcium oxide CaO, and not CaO2?
Mandarinka [93]
The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 cation.

Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion.

When the charges of the Calcium +2 and the Oxygen -2 are equal and opposite, the ions for an electrical attraction. (Remember Paula Abdul told us "Opposites Attract")

This one to one ratio of charges makes the formula CaO

You have 15.0 L of nitrogen gas at 100°C and 200 kPa. What volume of gas will you have at STP?
Pavel [41]
Actually, you do NOT need to calculate the number of moles, so you do NOT need to convert the volume and pressure. (You DO have to convert the temperature.) That's because for this problem, pV/T is constant, so the units cancel (but the temperature scale matters). 

<span>200kPa * 15L / 373K = 101kPa * V / 273K </span>
<span>V = 21.7 L </span>
