There are 4 moles of spectator ions that remain in solution.
The equation of the reaction is;
Na2CO3(aq) + Pb(NO3)2(aq) -------> PbCO3(s) + 2NaNO3(aq)
We have to determine the limiting reactant. This is the reactant that yields the least amount of product. Note that the spectator ions are Na^+ and NO3^- that form NaNO3.
For Na2CO3
1 mole of Na2CO3 yields 2 moles of NaNO3
3 moles of Na2CO3 yields 3 × 2/1 = 6 moles of NaNO3
For Pb(NO3)2
1 mole of Pb(NO3)2 yields 2 moles of NaNO3
2 moles of Pb(NO3)2 yields 2 × 2/1 = 4 moles of NaNO3
We can see that Pb(NO3)2 is the limiting reactant.
Since [NaNO3] = [Na^+] = [NO3^-], it follows that there are 4 moles of spectator ions that remain in solution.

Answer:
Option 3 or C An ion is all in Electrostatic forces so it's c if its not I'll work it out for you
Hello!
A biconditional statement is when one conditional statement and it's converse is true.
A conditional statement is an "If <em>hypothesis</em>, then <em>conclusion</em>" statement.
A converse statement is an "If <em>conclusion</em>, then <em>hypothesis</em>" statement.
Looking at this, both of these statements have their hypothesis and conclusion switched.
Thus, a biconditional statement is a "<em>Hypothesis</em> IFF <em>conclusion</em>." In this statement, IFF means if and only if.
Therefore, when IFF is used in a biconditional statement, it means if and only if.

The answer is A (3,2,1,3)
