<span>The answer is hypertonic. In osmosis, water
molecules move from a hypotonic solution to the hypertonic solution, through a
semipermeable membrane. This occurs until
both solutions become isotonic relative to each other. In osmosis, only
the movement of water molecules occurs since the ions are large enough to pass
through the pores of the semipermeable membrane,
in this case, the cell membrane. Due to
loss of water in the process of osmosis, the cells in the fingers of the swimmers
shrunk hence looked shriveled.</span>
It knows that when water evaporates, it carries heat energy away with it.
So your body puts some water out on your skin, and hopes that it will
evaporate. We call that "perspiring" or "sweating".
Answer:
A stronger acid is needed to neutralize the reaction.
Explanation:
Neutral pH solutions are because the acid counteracts the effect of the base, and vice versa.
Both chemical products, both acid and base, reach a pH of 7, which indicates the neutrality of the solution in the reaction, that is, the solution is neither acidic nor basic but NEUTRAL.
The higher the alkalinity of the base, the greater the acidity of the acid will be needed to balance and balance the pH to give neutrality as the final product.
Answer: Fe2O3
Explanation:
5.60 g Iron Oxide
- 3.92 g Iron
===========
= 1.68 g Oxygen
Convert Fe and O to moles:
3.92 g Iron/55.85 = 0.0702 moles Fe
1.68 g Oxygen/16 = 0.105 moles O
The ratio of O to Fe is 1.50. There are 3/2 O for each Fe. Multiply by 2 to get whole numbers: 2Fe for every 3O: Fe2O3
Answer:
Atomic mass is never an integer number for several reasons
