Ethyne because Ch4 is the most common, and the alkalies are a part of unsaturated hydrocarbon
Potassium Iodide have a lot of strong bonds which requires a very high temperature (high energy) to break them and change into a different state of matter.
Answer:
The approximate density of a high-leaded brass is δ = 8,40 g/mL
Explanation:
Lead brasses are used for their high machinability and atmospheric corrosion resistance. To obtain the density of this solid solution you need to do the weighted average, thus:
δ =
<em>δ = 8,40 g/mL</em>
