0.005 is the correct answer i hope this helps man :)
Metals are usually givers of electrons.
Answer:
As
Explanation:
For any element to exhibit the pattern of ionization energy shown in the question, it must possess five electrons in its outermost shell. These five electrons are not lost at once. They are lost progressively until the valence shell becomes empty. The ionization energy increases steadily as more electrons are lost from the valence shell.
The only pentavalent element among the options in arsenic, hence the answer.
During a chemical reaction, the stuff that reacts together are the reactants. The stuff that is made during the reaction are the products. A catalyst is something that can be added to the reaction that allows it to react faster, but does not get used up during the reaction.
Answer:
Repetition
Explanation:
In the world of science, experiments are regularly conducted to test out hypotheses. These experiments are however, not conducted by scientist once to derive a result. They are rather conducted multiple times (repeated) to ascertain the accuracy i.e not as a result of random occurrence. The experiments that undergo multiple trials are said to undergo REPETITION.
This is the case of the scientist in this question, who is conducting an experiment to test what temperature causes the fastest growth rate in sunflower plants. He conducted the experiment multiple times, making it an example of REPETITION.
N.B: Replication is when the experiment is re-conducted by another scientist to see if same result is derived.
