Answer:

Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

How many ml of a 14. 0 m nh3 stock solution are needed to prepare 200 ml of a 4. 20 m dilute nh3 solution?.

Lilit [14]

Answer:

60 mL

Explanation:

200 mL = 0.2 L

We know that:

Molarity = Moles / Liters

So:

4.20 M = moles / 0.2 L

moles = 4.20 x 0.2 = 0.84

Then:

14.0 M = 0.84 moles / Liters

Liters = 0.84 moles / 14.0 M = 0.06 L

Since they want the answer in mL, convert 0.06 to get 60 mL

Phosphorus has three electrons in its 3p sublevel and sulfur has four. Phosphorus should have the lower ionization energy but it

Nadya [2.5K]

Answer:

Explanation:

First of all it is important to know that a half filled orbital is particularly stable. In phosphorus all the electrons occur singly in the 3p sublevel minimizing inter electronic repulsion hence it is more difficult to remove an electron from this energetically stable arrangement. In sulphur, electrons are paired in one of the 3p orbitals thereby lowering the energy of that level due to instability caused by interelectronic repulsion between two electrons in the same orbital.
