Gas.
Solid is the slowest; it stays together, so the molecules don't move much.
Liquid is the middle; it stays together for the most part, but it can move.
Gas is the fastest; they can move all over the place!
Answer:
17g
Explanation:
4NH3 (g) + 502 (g) –> 4NO (g) + 6H20 (g)
Mass of O2 mole = 32g
Therefore 5O2 = 160g
Mass of NH3 mole = 17g
Therefore 4NH3 = 17 x 4 =68g
Required amount of NH3 = 68 x 40/160 = 17g
Answer:
It's explained by nebular theory, which describes the forces and processes at play as a nebula spins and accretes into a star and its planets orbiting it. A key piece of information to always keep in mind is that the force of gravity is responsible for accretion and all the objects it forms.

Answer:
d. [Ar] 4s²
Explanation:
The ground state electron configuration is the electron configuration of an atom with lower energy levels. The electron configuration for Titanium (Ti) is:
Ti = [Ar] 4s²3d² <em>-By Aufbau principle-</em>
For Ti²⁺, the ground state electron configuration is removing the 3d² electrons.
That means that ground state electron configuration for Ti²⁺ is:
<em>d. [Ar] 4s²</em>
<em></em>
