The answer is nucleation because can turn liquids into solids.
The bubbles indicate that there is a gas dissolved in the liquid, which may remain dissolved when the liquid is very cold, inside the refrigerator.
When the temperature of the liquid increases, it reduces its ability to dissolve the gas and the gas escapes (bubbles) from the liquid.
At the end, the behavior of the liquid permits you to conclude that the liquid is a mixture because it has a gas dissolved in it.
One lone pair, as there is a single covalent bond between the hydrogen and the carbon, and a triple covalent bond between the nitrogen and the carbon, leaving two free electrons/one electron pair on the nitrogen..... I think ((:
Geraldo can add a pollutant with slightly basic nature so he will have a solution of neutral pH of 7.
<h3>What is pH?</h3>
The pH of a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution.
The pH of 6.5 means that the solution is acidic.
By adding a pollutant which is slightly basic in nature, Geraldo will have a solution of neutral pH which is a pH of 7.

Answer:
115.936g
Explanation:
Ca(ClO3)2 -->CaCl2 +3 O2
One mole of calcium chlorate give up three moles of oxygen.
Molar mass of calcium chlorate is
40+(35.5+16*3)*2 = 207g/mol
Therefore there are
250g/207=
1.207mol of calcium cholrate...
So 1.207*3=3.623mol
Therefore 3.623mols of Oxygen must be produced.
Mass of the oxygen gas is equal to 3.623mol*32g/mol =115.936g
(O2 molar mass 32g/mol)
Cheers
