Select the words that correctly fill in the blanks for the statement: the p sub level has orbitals that are -shapes

6 , dumb-bell

Explanation:

The orbitals are in S - P - D - F, being 2 - 6 - 10 - 14 electrons respectively. The orbitals are shaped in the dumbell manner because there will be 3 on one side, and 3 on the other, equalizing the force on each other and shaping it like a dumbell

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
