Answer:
wave length=speed*frequency
=36*6
=216 m
Assuming that the reactants are:
(NH4)2SO4 (aq) + Ba(NO3)2 (aq)
and the products are:
BaSO4 (s) + 2NH4NO3 (aq),
then you will have to determine which product is insoluble. You should have access to solubility rules to help you determine this.
According to the solubility rules, the following elements are considered insoluble when paired with SO4:
Sr^2+, Ba^2+, Pb^2+, Ag^2+, and Ca^2+
Therefore, the precipitate will be BaSO4 (s).
<span>oxidizing agent removes an electron from other specie
the oxidizing agents are reduced due to loss of electrons
</span><span> F2 is reduced from neutral state to 1- so it act as an oxidizing agent
</span>so correct option is A
hope it helps
