Aplant fertilizer contains 19 % nitrogen (n) by mass. in a container of soluble plant food, there are 10.0 oz of fertilizer. how many
grams of nitrogen are in the container?

Ithink is a because if say increased in electronegativity

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.
