That would be a depression..
Answer:
D
more protons in the nucleus pull the electrons in, making the atomic radius smaller
Explanation: A p E X !! :)
The titration would require the same amount of NaOH.
<h3>Number of moles and dilution</h3>
The number of moles of solute in a solution remains the same irrespective of the amount of water added to dilute the solution.
This is in accordance with the dilution law which says that the number of moles of a solution before dilution is the same as after dilution.
Thus, the amount of NaOH needed to neutralize the vinegar will remain the same for a complete reaction since the number of moles of solute in the vinegar has not changed.

The balanced chemical reaction would be
<span>fecl2 + 2naoh = fe(oh)2(s) + 2nacl
Initial amounts of the reactants are given, so, we need to determine which of the reactants is the limiting reactant and use this amount to determine what is asked. However, what is being asked is how many of the FeCl2 is used in the reaction, showing that it is NaOH that is the limiting reactants. Thus, we just use the initial amount of NaOH and relate the substances by the chemical reaction as follows:
6 mol NaOH ( 1 mol FeCl2 / 2 mol NaOH ) = 3 mol FeCl2
Therefore, 3 moles of FeCl2 is used up and 3 moles of FeCl2 is also left after the reaction.</span>
