Check the statements below that are TRUE. Group of answer choices The A/HA term is unitless The units on [A] and [HA] don't matter because A/HA is unitless You can use whatever numbers are provided for [A] and [HA] even if the initial concentrations are not in the same solution. The units on [A] and [HA] can be in moles or molarity because the final volume will cancel in the ratio

According to arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. further, acid and base reacts to form salt and water.consider following example.hcl    +      h2o          →      cl-          +      h3o+here, hcl has donated a proton, hence it is an acid.now consider following reactionhcl      +      naoh            ↔      nacl      +        h2oin this reaction, hcl donates proton, hence it is acid. on other hand, naoh donates hydroxyl ion (i.e. hence it is a base.   

Sorrr but idk whats its abou 9

The heat flow would be from he counter to the ice cube, because the ice cube is colder than the counter and heat moves from high heat to low heat.
