W=m₁/m₀=2^(-t/T)
t=4.6·10⁹ years
T=5·10¹⁰ years
w=2^(-4.6·10⁹/5·10¹⁰)
w=0.9382
w=93.82%

First part is polar, second part is non-polar. Use the saying "like dissolves like". Substances that are alike in polarity are more likely to dissolve one another.
Answer:
See detailed explanation.
Explanation:
Hello!
In this case, for the described chemical reaction, we can proceed as follows:
A) For the complete chemical reaction we note down every reacted and produced species as well as the proper balancing process:

In which gaseous bromine may give off.
B) The dissociated ionic equation requires the ionization of the aqueous species in ions, expect for chlorine which is not ionized:

C) For the net ionic equation we cancel out the sodium ions as they are at both reactants and products:

D) Based on C) we infer that the spectator ions here are the sodium ions.
Best regards!
