In an experiment you are asked to react hydrochloric acid with sodium hydroxide. when measuring the volume of the reactants, which instrument would give the greatest precision?

When measuring the volume of the reactants, the instrument that would give the greatest precision would be a graduated  cylinder since it has marks showing the volume of the substance measured. Hope this answers the question. Have a nice day.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

All the elements are arranged by melting points on the periodic table. in row they go from metals to gasses. in the row from sodium to argon, sodium is more reactive than the one on its right, magnesium.
