Radda [10]3 years ago

Here is your answer:

Remember that potential energy is the energy a object has when it's NOT moving, and kinetic energy is when a object has energy when it IS moving. So examples of this kid of transformation would be kicking a soccer ball at first the soccer ball has potential energy because it's not moving but it has potential to move then when someone kicks the soccer ball it has kinetic energy because the ball is not moving.

Example one: when the video first begin "the ball had potential energy and when the ball swung and hit it that potential energy turned into kinetic energy."

Example two: As the video moves on and the two pillars crashed down it caused another ball to move, at first the "ball had potential energy because it was not moving then when the ramp went down it caused the ball to gain kinetic energy."

Example three: At the end of the video the ball push down a row of wooden blocks then lead to it hitting a "bowling ball across the finish line even though the ball moved slowly and not far it still came from potential energy into kinetic energy."

Hope this helps!

What is the difference between Polar and Non-Polar molecules?
Alekssandra [29.7K]
<span>When you have a polar molecule, your bonds will not cancel out. This means that in a polar bond, the electronegativity of the atoms will attend to be different. For non-polar bonds the electro-negativity of the atoms will also be equal. In a polar bond you will have an unequal sharing of electron pairs which causes a molecular dipole. I hope this helps.

Which sample contains the fewest atoms? a. 10 g of c b. 10 g of ne c. 10 g of f d. 10 g of n e. 10 g of o
Lerok [7]

The molar mass and the mass of the substance give the moles of the substance. The 10-gram sample of neon (Ne) has the fewest atoms. Thus, option b is correct.

<h3>What are moles?</h3>

Moles of the substance are the ratio of the molar mass and the mass of the substance. The moles of each atom with respect to the Avagadro's number (Nₐ) is given as,

Moles = mass ÷ molar mass

  • Moles of carbon (C) = 10 ÷ 12

= 0.83 Nₐ atoms

  • Moles of neon (Ne) = 10 ÷ 20

= 0.5 Nₐ atoms

  • Moles of fluorine (F) = 10 ÷ 19

= 0.52 Nₐ atoms

  • Moles of nitrogen (N) = 10 ÷ 14

= 0.7 Nₐ atoms

  • Moles of oxygen (O) = 10 ÷ 16

= 0.63 Nₐ atoms

Therefore, option b. 10 gm neon has the fewest atoms.

How do i find a ionic formula? <br><br>for example Ca2+ &amp; S2-​
jeka94

Example #1 write the chemical formula for Calcium Oxide

Step 1

-Find the Atomic symbol of the metal and non-metal on the periodic table

CaO

Step 2

Find the charges for Calcium and Oxygen

which are Ca 2+ and O 2-

Step 3

Balance out the charges

They are already balanced out

Here´s the chemical formula for Calcium Oxide

CaO

Example 2 write the chemical formula for Aluminum Oxide

Step 1

-Find the Atomic symbol of the metal and non-metal on the periodic table

A

l

O

Step 2

Find the charges for Aluminum and Oxygen

Which are Al 3+ and O 2-

Step 3

Balance out the charges

You need 2 Aluminum and 3 Oxygen to balance the charges

Al 3+ O 2-

Al 3+ O 2-

= 6 + O 2-

= 6-

Step 4

If you need more then one element to balance out the charges you identify that by using subscripts

Heres your chemical formula for Aluminum Oxide

Al_{2} O_{3}
