If it takes 35 mL of 0.05 M HCl to neutralize 315 mL of NaOH solution, what is the concentration of the NaOH solution?

idk

explanation:

dasdad

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
