noble gas configuration [He]2s^22p^4
Answer:
(b) When 20.0 g of nitrogen and 32.0 g of oxygen are combined and allowed to react in two separate experiments, both times the product isolated from reaction contains 14.0 g of nitrogen and 32.0 g of oxygen.
Explanation:
The law of definite proportion states that a gen chemical compound always contains its constituent elements in a fixed ratio by mass, independent on the method of preparation.
The molar mass of Nitrogen and Oxygen would always remain the same, allowing for exact reactant masses (or mole ratio) irrespective of the given amount of sample.
The entire range of electromagnetic frequencies is known as C, the electromagnetic spectrum.
Television remote controls (D) do NOT use radio waves (they use infrared radiation).
A material that allows some, but not all, light to pass through it, would be described as translucent (C).
