Answer:
Electron: A negatively charged particle found circling or orbiting an atomic nucleus. An electron, like a proton is a charged particle, although opposite in sign, but unlike a proton, an electron has negligible atomic mass. Electrons contribute no atomic mass units to the total atomic weight of an atom.
Explanation:
Answer:
Atom
Explanation:
The atom is the simplest unit of matter that has all the properties of an element. It is made up of 3 subatomic particles: protons, electrons and neutrons.
Knocking out the other choices, the cell is the basic unit of life. An electron is only part of an atom, which has its own properties, while a compound is a combination of two or more elements that are chemically bonded.
Answer:
5.18.
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) = 5.176 ≅ 5.18.</em>
