In aqueous solution, classify these compounds as strong acids, weak acids, strong bases, weak bases, or other hno3 hbr hf h2co3

Missing question: NH3, CH3COOH, HNO3, HCl, CsOH, H2CO3, H2SO4, Ca(OH)2, HI, HCN, H2CO3.

Strong acids: HNO₃(nitric acid), HBr (hydrobromic acid), HCl(hydrochloric acid), H₂SO₄(sulfuric acid), HI(hydroiodic acid).

Weak acids:CH₃COOH(acetic acid), HF(hydrofluoric acid), H₂CO₃(carbonic acid), HCN(cyanic acid)

Strong bases: CsOH(cesium hydroxide), Ca(OH)₂(calcium hydroxide).

Weak bases: NH₃(ammonia).

the answer would be c

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.
