Identify the brønsted-lowry acid, the brønsted-lowry base, the conjugate acid, and the conjugate base in each reaction: (a) (ch3)3n(aq)+h2o(l)⇌(ch3)3nh+(aq)+oh −(aq) (b) hno3(aq)+h2o(l)⇌h3o+(aq)+no3−(aq)

Answer :

(a) and are conjugate acid and base respectively.

(b) and are conjugate acid and base respectively.

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

(a) The given equilibrium reaction is,

In this reaction, is an acid that donate a proton or hydrogen to base and it forms and are conjugate acid and base respectively.

(b) The given equilibrium reaction is,

In this reaction, is an acid that donate a proton or hydrogen to base and it forms and are conjugate acid and base respectively.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

the answer is b. dilution
