Mr. Avogadro has set up 4 jars with one mole of each the following substances: Iron
Sodium Chloride
Sodium Bicarbonate (NaHCO3)
Aluminum
His clever and intelligent students notice that all of the amounts of the various substances are different from one another, even though they are all ONE MOLE. Explain the reason why each amount in the jar is different in terms of the mole. Then, calculate the molar mass for each of the substances. Circle your your answers and include the unit used for molar mass.

please answer asap :)

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

Which of these is a physical property

Answer explain why it is not possible to deduce a complete order of reactivity.
