The reactivity of an atom arises from

a. the number of electrons in the nucleus.
b. the number of protons in the nucleus.
c. the number of electrons in the valence shell.
d. the atomic mass.

In which phase(s) do the molecules take the shape of the container?

There is a single path for electrons. the current decreases when additional resistors are added. the current will be the same in each resistor. these statements best describe a(n) circuit.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed
