According to bronsted-lowry definition of acids and bases what substances form when hci dissociates in water

So the Bronsted-Lowry definition of acid and bases states that an acid is a subtance that can donate a proton to another substance in a chemical reaction, while a base is a substance that can accept a proton from another substance in a chemical reaction.

It also states that the products that are formed from these acids and bases reacting are called conjugate acids and bases. Where a conjugate acid is define as an acid generated as a result of a base accepting a proton, while a conjugate base is defined as the base generated as a result of an acid donating a proton.

With this is in mind, what substances form when HCl dissociates in water?

Here is the reaction:

HCl + H2O ⇒ H3O+ + Cl-

The substances that form are H3O+ which is a conjugate acid and Cl- which is a conjugate base, all according to the definition of a Bronsted-Lowry acid and base.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
