Answer:
Waves are created by energy passing through water, causing it to move in a circular motion.
Explanation:
A precipitation reaction is a reaction that yields an insoluble product.
When two solutions which could react are mixed together, they interact with each other and products are formed. These products could be aqueous solutions or solids.
When a mixture of two aqueous solutions react chemically to yield an insoluble product, we can say that a precipitation reaction has taken place.
We shall now proceed to fill in the missing products in each of the reactions;
a) Ca(NO3)2 (aq) + CuSO4 (aq) → CaSO4(s) + Cu(NO3)2 (aq)
b) 2KC2H302 (aq) + COSO4 (aq) → Co(C2H302)2 (s) + K2SO4(aq)
c) 2K3PO4 (aq) + 3Mg12 (aq) → 6KI(aq) + Mg3(PO4)2 (s)
d) FeCl3 (aq) + 3NH4OH (aq) → Fe(OH)3 (s) + 3NH4Cl(aq)

Because the Hydrogen and Oxygen have a slight positive and negative charges that attract them to each other. As to why they bond in that ratio is because they're balanced that way, their electrons balance their covalent bond. This ratio of two Hydrogen and one Oxygen is well balanced therefore easily formed
Answer: The concentration of solutes is the same both inside and outside of the cell : isotonic
The concentration of solutes is less outside the cell than inside the cell : hypotonic
the concentration of solutes is greater outside the cell than inside it: hypertonic
the diffusion of water across a selectively permeable membrane: osmosis
the movement of molecules from a region of high concentration to a region of low concentration by means of random molecular motion : diffusion
a membrane that allows only specific molecules to move into or out of the cell : selectively permeable
Explanation:
The solutions having same osmotic pressure and hence same molar concentration are termed as isotonic.
If a solution is of lower osmotic pressure it is called as hypotonic with respect to the concentrate solution.
The more concentrated solution is said to be hypertonic with respect to the dilute solution.
Osmosis is defined as the process in which molecules of a solvent tend to move through a semipermeable membrane from a region of low concentration solution to a region of more concentrated solution.
Diffusion can be defined as a phenomenon that occurs in liquid or gases which is the process of movement of solute particles from area of high concentration to low concentration.
Selectively permeable membrane is a membrane which allows selective movement of molecules.
