Answer:
Energy
Explanation:
Energy can simply be defined as the ability to do work. It is a measure of the amount of work a body or object can do. The more the work a body is able to accomplish, the more the energy it posses. The unit of energy is always expressed in joules.
Mass is the amount of matter in a substance.
Velocity is rate of change of displacement with time.
Since there is one carbon with 4 Fluorines attached to it, and both compounds are no metals, we use the covalent method for naming,
Here we ignore the prefix for the first element if it is 1. Mono. Then pay attention to the second one, it would be tetra, because tetra means 4. Here there are 4 fluorines.

CF4 = carbon tetrafluoride.
Answer:
27.38 g
Explanation:
- CH₃NO₂ (l) + 3O₂ (g) → 4CO₂ (g) + 6H₂O (l) + 2N₂ (g) ΔHorxn = -2836 kJ
The value of ΔHorxn tells us that when 1 mol of CH₃NO₂ is burned, 2836 kJ of heat are produced. With that in mind we can<u> calculate how many moles of CH₃NO₂ were burned when 1273 kJ of heat were produced</u>:
- 1273 kJ * 1mol / 2836 kJ = 0.4489 mol
Then we <u>convert 0.4489 moles of CH₃NO₂ to grams</u>, using its <em>molar mass</em>:
- 0.4489 mol * 61 g/mol = 27.38 g
