Answer:

The correct option is: D) Subatomic Particle

Explanation:

Electrons are the negatively charged, stable sub-atomic particles that exist in <u>discrete energy levels, called the electron shells</u>, around the nucleus of an atom.

Each electronic shell consists of a fixed number of electrons and these electronic shells are denoted by the symbol K, L, M, N, and so on.

<u>Therefore, electron is the sub-atomic particle that exists at a discrete energy level.</u>

HELP!!!!!

Answer:

5.17.

Explanation:

<em>∵ [H₃O⁺][OH⁻] = 10⁻¹⁴. </em>

[OH⁻] = 1.5  x 10⁻⁹ M.

∴ [H₃O⁺] = 10⁻¹⁴/[OH⁻] = 10⁻¹⁴/(1.5  x 10⁻⁹ M) = 6.66 × 10⁻⁶ M.

∵ pH = - log[H₃O⁺]

<em>∴ pH = - log(6.66 × 10⁻⁶ M) = 5.17. </em>

-BARSIC- [3]
The two compounds shown indeed have tha same molecular formula, C5 H11 NO2. One of the molecules has a group NH2 and a group COOH, the other molecule has a NOO group, that makes that the two isomers have a completely different structure, with the atoms arranged in a completely different order. <span>This kind of isomers fits in the definition of structural isomers, so the answer is structural isomers.</span>
