Answer:
Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
Explanation:
What chemical reaction??? Very vague
of oxygen at STP would be required to react completely with 38.8g of propane.
<u>Given that :</u>
molar mass of propane = 44 g/mol
mass of propane = 38.8 g
∴ Moles present in 38.8 g of propane =
= 0.88 mole
<u>applying rule of balanced equations </u>
1 mole of propane = 5 moles of oxygen
0.88 mole of propane = 5 * 0.88 = 4.4 moles of oxygen
Note : volume of 1 mole of oxygen at STP = ![22.4 dm^3](https://tex.z-dn.net/?f=22.4%20dm%5E3)
∴Total volume of oxygen required at STP = 22.4 * 4.4 = ![98.56 dm^3](https://tex.z-dn.net/?f=98.56%20dm%5E3)
Hence we can conclude that the volume of oxygen at STP required to react completely ![98.56 dm^3](https://tex.z-dn.net/?f=98.56%20dm%5E3)

Answer:
second one
Explanation:
According to the formula that I learned it is
![d = \frac{m}{v}](https://tex.z-dn.net/?f=d%20%3D%20%20%5Cfrac%7Bm%7D%7Bv%7D%20)
m for mass, v for volume
