Answer:
Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula N ₂O. At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen.
Explanation:
Speed is actually instantaneous speed, the speed an object is moving at that very instant.
But average speed is the total distance traveled divided by the total time.
Let's say you travelled 10 miles in 2 hours, your average speed would be 10 divided by 2, which is 10 miles / hr.
But during those 10 miles you may be accelerating, decelerating and be travelling 1 mile/hour and 20 miles/hour at another point. But your average speed would be total distance / total time. So your instantaneous speed can change throughout that period of time.

Answer:
The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system. - <u>Le Chatelier's principle</u>
A molecule that donates a proton when it encounters a proton acceptor. - <u>Bronsted-Lowry acid</u>
Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid. - <u>Neutralization</u>
It ionizes completely when dissolved in water. - <u>Strong acid</u>
The shift in the position of equilibrium caused by the addition of a participating ion. - <u>Common ion effect</u>
It only partially ionizes when dissolved in water. - <u>Weak electrolyte</u>
It is capable of acting as either an acid or a base depending upon the solute. - <u>Amphoteric solvent</u>
The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base. - <u>autoprotolysis </u>
A chemical species that bears both positive and negative charges. - <u>zwitter ion</u>
Answer:
4.99 x 10⁻⁷ meters or 499 nanometers
Explanation:
Use the formula:
λ = c/ν, where λ = wavelength, c = the speed of light (it's constant, 2.998 x 10⁸ m/s), and ν = frequency
λ = (2.998 x 10⁸ m/s)/(6.01 x 10¹⁴ 1/s)
λ = 4.98835 x 10⁻⁷
Round to nearest hundreth and you get 4.99 x 10⁻⁷ meters, or 499 nanometers.
