When you are boiling eggs for example the pot with water is hot and you can see bubbles in the pot. This is called boiling water. When the eggs are in there they are boiling to make hard boiled eggs. Depending on how long it is in there determines the outcome. On the surface of the egg shell you may also notice little bubbles all around the shell which means it is boiling.

Hope this helps! :3

Bumek [7]

Answer:

The correct answers are: Each oxygen of carbonate ion has -2/3 or -0.67 charge.

Bond order of each carbon‑oxygen bond in the carbonate ion = 1.33

Explanation:

The carbonate ion (CO₃²⁻) is an organic compound, in which a carbon atom is covalently bonded to three oxygen atoms. The net formal charge on a carbonate ion is −2.

The carbonate ion is resonance stabilized and has three equivalent resonating structures, which exhibits that all the three carbon-oxygen bonds in a carbonate ion are equivalent.

In the resonance hybrid of carbonate ion, the negative charge is equally delocalized on all the three oxygen atoms.

Thus, each bonded oxygen has -2/3 or -0.67 charge.

In a carbonate ion there is one double bond oxygen (C=O) and two single bonded oxygen (C-O). Bond order of 1 C=O is 2 and bond order of C-O is 1.

∴ Bond order = sum of all bond orders ÷ number of bonding groups = (2+1+1) ÷ 3 = 1.33

I mean this is pretty obvious it's D. life expectancy is sort of close but not really. B is close too but it's not it bc that's not what health is. you could be over weight and not be sick and it still isn't healthy. and C isn't close at all. hope this helps, have an amazing day :)
