Dados os elementos A(Z=49), B(Z=55) e D(Z=3), coloque-os em ordem crescente dos valores de potencial de ionização e eletroafinidade. O elemento de maior eletronegatividade é o que apresente o seguinte número atômico:

Translaion: Given the elements A (Z = 49), B (Z = 55) and D (Z = 3), place them in crescent order with two values ​​of ionization potential and electro-affinity. Or element of greater eletronegatividade é or that appears or follows atomic number:

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.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.
