Explanation:

The element that will have similar reactivity with sodium will be an alkali metal in Group 1 on the periodic table. The elements can be Li, K, Rb, Cs or Fr.

  • Group 1 elements have just one valence electron and they are purely electropositive metals.
  • They are usually very reactive and not found easily in free state in nature.
  • Chemical reactivity is a similar property in a group. It is known that elements in the same group will react in the same way.
  • Chemical reactivity is a function of the valence electrons.
  • All group 1 elements have just an electron in their valence shell.

How many molecules are in 4.50 moles of H2O?
alisha [4.7K]
C can be the only correct answer - 6.023 x 10^23 is the amount of molecules in a mol of an element. 4.5 x 6.023 x 10^23 can not equal anything but C.

4.5 x 6.023 x 10^23 = 2.71035 x 10^24
