Answer:
Explanation:
First you should calculate the volume of a big sphere,so:
Then you calculate the volume of a small spehre, so:
Finally you subtract the two quantities:
Answer:
0.05g/ml
Explanation:
density is equal to mass over volume check pic for more info
Yes it is polluting the river with everything the manufaturing plant gives off such as the chemicals released in the air
The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge (neutrons have zero charge). Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.Hoped this helped
To dissolve one substance, attractions between solute and solvent particles must be formed, steps involved are:
<h3><u>Formation of a solution:</u></h3>
- A physical process, not a chemical one, takes place when a solute and a solvent combine to produce a solution.
- In other words, by applying the right separation techniques, both the solute and the solvent may be recovered in chemically unaltered forms.
- It is claimed that two substances are entirely miscible when they combine to create a single homogenous phase in all ratios. Water and ethanol mix well, much like different gas combinations do.
- When two substances, like oil and water, are fundamentally insoluble in one another, they are said to be immiscible.
- We have already talked about several examples of gaseous solutions, such as the atmosphere of Earth.
- Thus, a system that has two or more compounds homogeneously (in a single phase) dissolved in it is called a solution. It is the homogenous mixture formed when a solute dissolves in a solvent.
