Which solution is an example of an electrolyte A.)Methanol in water B.)Potassium iodide in water C.)Pentane in octane D.)Sucrose
zhannawk [14.2K]

Answer:

The correct answer is B.)Potassium iodide in water

Explanation:

An electrolyte is a compound that can dissociate into ions when is dissolved in a solvent. The resulting solution has the ability to conduct the electricity because there are electrical charges (ions) in the solvent. The most common electrolytes are soluble salts.

From the options, methanol (A), pentane (C) and sucrose (D) are organic compounds that cannot be dissociated into ions in the solvents in which are soluble. The only correct option is (B), because potassium iodide (KI) is a soluble salt that disociates into ions (K⁺ and I⁻) when is dissolved in water:

KI → K⁺ + I⁻

Write the electron configuration, the orbital notation, and the noble gas notation for the following elements:
V125BC [204]

Answer:

See explanation

Explanation:

The electron configuration of an atom means a detailed arrangement of the electrons in the atom in orbitals. It normally begins from the least energetic orbitals to the most energetic orbital.

For each of the elements, their electronic configuration in terms of the nearest noble gas is shown below;

P - [Ne] 3s2 3p3

I- [Kr] 4d10 5s2 5p5

Pb- [Xe] 4f14 5d10 6s2 6p2

F- [He] 2s2 2p5

During the day, due to the existence of sunlight, the procedure of photosynthesis elevations over that of respiration. Photosynthesis uses carbon dioxide to produce carbohydrates removing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis decreases. This, therefore, drives the rate of respiration to surpass the speed of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is dismissed.

<h3>What is photosynthesis?</h3>
  • Photosynthesis is the process by which manufacturers use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
  • The primary position of photosynthesis is to transform solar energy into chemical energy and then reserve that chemical energy for prospective use. For the most part, the planet's living designs are powered by this process.
  • An illustration of photosynthesis is how plants convert sugar and significance from water, air, and sunlight into energy to grow. Description of photosynthesis is the procedure through which plants use water and carbon dioxide to assemble their food, grow and remove excess oxygen into the air.
