ANSWER ASAP PLEASE Which best describes the role of communication in scientific investigations? Communication can help identify good scientific questions to further investigate.
Communication is not necessary once the data are collected because the scientists can do the data analysis themselves.
Communication should not be used in planning the experimental design because the scientists want to have original ideas.
Communication is important because the scientists need to convince other researchers not to challenge their results.

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.
