How do you separate a mixture of sodium chloride and potassium trioxonitrateV

See explanation

Explanation:

We separate substances based on their important properties such as reaction to heat, solubility in water, magnetic properties, etc.

To separate sodium chloride and potassium trioxonitrateV, we need to heat the solution. KNO3 dissolves at a high temperature and crystallizes out as the solution is cooled.

Hence when we heat the solution, KNO3 dissolves, as we cool the solution, solid KNO3 crystals are obtained while NaCl remains in solution.  We have now separated the two salts in the solution.

Note that the solubility of NaCl is almost independent of temperature.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
