Answer:
+3
Explanation:
The oxidation number of a specie is the charge that it appears to have as determined by some arbitrary rules.
If we look at the reaction, we will notice that arsenic is more electro positive than chlorine so it is likely to function as the reducing agent in the reaction, loosing three electrons to have an oxidation number of +3 in the product.
Butane is
from the family of alkanes with –ane as its family name. The but- prefix stands
for having four carbon atoms. The C4H10 is the general formula of butane and
can also represent other forms or structures of butane. However if the question
asks for the molecular formula of butane, think of how many electrons it can
share to the hydrogen atom. The carbon atom can share 4 and hydrogen 1. So if the three hydrogen atoms are attached
to the first carbon, the other shared electron is attached to the second
carbon. The second carbon atom can accommodate two hydrogen and 1 carbon. The
third carbon can accommodate 2 hydrogen atoms and 1 carbon and the fourth
carbon can accommodate 3 hydrogen atoms. The molecular formula is
CH3-CH2-CH2-CH3.
It is not B it is A, wave 1 waves are more spread apart so that means it has a bigger wave length, and the frequency is how many waves there are in one second so the smaller waves would have the higher frequency so it would be A hope this helps.
Answer:
Fractional distillation
Explanation:
Heat the mixture upto 700°C
The compuond with low boiling point will evaporate first and the compound with higher boiling point will evaporate last.
