Answer:
3.04 atoms
Explanation:
because of the switzer theory
Answer:
In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level.
Explanation:
Whether an object will float or sink is dependent on its density, and on the density of the liquid it is placed in.
Answer:
1. the bottom layer
2. aqueous HCI
3. the top layer
4.aqueous NaOH
5. mostly in the diethyl ether layer
Explanation:
Pure dimethylformamide is considerably more polar than hexane hence thee two solutions will form two phases with the pure dimethylformamide as the bottom layer.
If we want to extract aniline from chloroform, HCl must be added in order to give a salt that can be extracted into the aqueous layer.
For a mixture of methylene chloride and diethyl ether, the diethyl ether layer will be found as the top layer since it is considerably less polar than methylene chloride.
Benzyl alcohol can be extracted from a solution of chloroform by adding NaOH and extracting it into an aqueous layer.
A large partition coefficient for the extraction of naphthalene into diethyl ether from water means that naphthalene will be found mostly in the diethyl ether layer.

Answer:
glucose and oxygen
Explanation:
plants use carbondioxide, water and sunlight to produce their food through photosynthesis so in return they produce oxygen into the air as by product and glucose
