Answer:
D
Explanation:
Because the silk took away the electrons to allow the rod to become positive. They cant be destroyed because of the law of conservation of charges. Also protons cannot move only electrons can.
I think the answer is it represent the shape of orbitals that electrons can occupy within an atom.

Answer:
The new concentration will be 0.01 M.
Explanation:
To determine the new concentration we use the following formula.
concentration (1) × volume (1) = concentration (2) × volume (2)
concentration (1) = 0.1 M
volume (1) = 100 mL
concentration (2) = unknown
volume (2) = 100 mL + 900 mL = 1000 mL
concentration (2) = [concentration (1) × volume (1)] / volume (2)
concentration (2) = (0.1 × 100) / 1000 = 0.01 M
Molarity=moles/liters. Take 42.9 g CaCl2 and divide it by the molar mass of CaCl2 which is 110.98. You get .387 moles. Finally divide .387 moles/ 45 L = .0086 M CaCl2
