How could you increase the potential energy of an apple you were holding?

If you're holding the apple at your waist, lift it to your mouth.
Potential energy relative to any level is proportional to its height 
above that level.  Increase that height, and you've increased the 
potential energy.
Since energy is conserved ... it never magically appears or 
disappears ... you need to tell where that extra energy for the 
apple came from.
It's exactly the work you did ... the force of your muscles acting 
through the distance you raised the apple ... that became the 
additional potential energy that the apple gained.

Question 21
Mumz [18]
There are 2 moles of O stones present in 88 grams of CO2. Why? Well, we can find the amount of moles present in 88 grams of CO2 by dividing the mass by the molar mass. The mass of CO2 comes out to be 88 grams. The molar mass of CO2 comes out to be 44 grams. Because 88 is the mass of CO2 and 44 is the molar mass of CO2, we can divide 88 by 44 to identify that there are 2.0 moles of O atoms present in 88 grams of CO2.

Your final answer: There are 2.0 moles of O atoms present in 88 grams of CO2. Your final answer to this question is D, or 2.0 moles. If you need to better understand, let me know and I will gladly assist you.
