Greenhouse gasses got their name from a greenhouse
Explanation:
Since greenhouses have plants inside in which the building lets sunlight in to the plants and greenhouse gasses trap heat. (sorry if my answer is confusing)
The reaction for magnesium iodide when put into water is as below
MgI2(s) → Mg^2+(aq) + 2I^-(aq)
when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .
Answer:
The answer to your question is D.
Explanation:
Potassium has 4 energy levels in the first level (A) has only 2 electrons,
in the second energy (B) level has 8 electrons, in the third energy level (C) also has 8 electrons and in the fourth energy level has only one electron.
Valence electrons are located in the outermost shell so Potassium has only one electron located in the shell D.
