It takes 222.46 mL of a 2.01 M HCl solution to neutralize 141.30 mL of NaOH solution. What is the concentration of the NaOH solution? Do not record units in your answer. Round to the tenths place or further.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

um i think it might be a car?
