Hi Khal75,
Experiment: How to seperate iron fillings
Iron fillings is a substance that attracts to magnets.
Answer - Separated using a magnet; magnetism
If you move a magnet around different solids with the iron fillings in it, it wil attract the iron to be able to seperate it.
Answer:
the third one
Explanation:
if you look at it mathematically its the one that makes the most sense
Answer: The percent yield of the reaction is 77.0 %
Explanation:
According to stoichiometry:
2 moles of 
produces = 2 moles of 
2.18 moles of is produced by=
of
Mass of =
percent yield =
This is how you convert gallons to liters.
- Gallon is a volumetric unit.
- 1 gallon equals 3.785 liters
- So, you create this conversion factor: 1 gal = 3.785 liter ⇒ 1 = 3.785 liter / 1 gallon.
- Therefore, you can multiply any amount in gallons by the conversion factor and get the equivalent amoun in liters.
- Examples:
- 1 gallon = 1 gallon × 3.785 liter / gallon = 3.785 liter
- 3 gallon = 3 gallon × 3.785 liter / gallon = 11.355 liter
- 15.25 gallon = 14.25 gallon × 3.785 liter / gallon = 53.936 liter
The heat energy needed is 2928800J. Mass is given as 20 (kg)
