A chemistry student is experimentally determining the boiling point of bromine. The experimental melting points are listed below from a
to e. Which one should he discard so that he can say his data is
precise?
a 59.0 °C
b 58.8 °C
C 58.5 °C
d 59,1°C
e 56.3 °

it means there are 3 atoms of oxygen

the answer would be b i believe

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
