In the reaction H20 + CO2 + 2NaOH --> Na2CO3 + 2H20 you have 18.5 grams of water, 24.6 grams
of CO2, and 40.2 grams of NaOH. Which reagent is limiting?

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

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