It’s Nitrogen (N) with a -3 charge
Whatever is on one side of the equation needs to be the same as the other. So K2CrO4+NaHSO3+H2O=NaHSO4+KOH+Cr(OH)3 you need to balance the equation between the = to make a balanced equation.
Magnetism: separates magnetic materials from non-magnetic. 3rd diagram
evaporation: separates a soluble solid by boiling off. 4th diagram
filtration: separates insolube solid from a liquid. 1st diagram
distillation: separates liquids with different boiling points. 5th diagram
chromatography: separates liquids of different colours. 2nd diagram
1. two or mor, chemically bonded
2. purify
3. magnetism, evaporation, filtration, distillation, chromatography
I believe sam's response is correct.
When human is riding a moving target with constant speed over a period of time, we tend to have a visual acceleration perception due to our optical movement.
This make people such as Carrie believes that the carousel horses are accelerating while it actually stayed at constant pace.
