Density = mass / volume
Density = 7.5 g / 5.0 cm3
Density = 1.5 g/cm3
The unites of measurement in a data table should be shown in the headings of some columns.
Answer:
Chlorine gas.
Explanation:
Hello!
In this case, the undergoing chemical reaction is:

Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:

Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.
