Which ionic compound is water soluble? a. cus b. nh4no3 c. srso4 d. znf

NH₄NO₃

Explanation:

All nitrates are soluble in water.

The solubility is based on the ionic product and solubility product of a compound.

If the ionic product exceeds the solubility product then the compound is insoluble.

In case of ammonium nitrate the solubility product is very high and thus the ionic product could not exceed the solubility product easily hence ammonium nitrate is soluble in water.

For other given compounds they have low solubility product and are thus less soluble.

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.
