Answer:
Double bond
Explanation:
an alkene is a unsaturated hydrocarbon which means that it contain at least one double bond
Answer:
Since electrons cannot have the same set of quantum numbers, a maximum of two can be in the n = 1 level, and a third electron must reside in the higher-energy n = 2 level. If there are two electrons in the n = 1 level, their spins must be in opposite directions.
Temperature. Water is an example. When water is at room temp. its liquid. When water is at boiling temp. It is a gas. And when water is at freezing temp. Its a solid.
Mass = 39.0 gal × (3.785 L/1 gal) × (1000 mL/1 L) × (0.789 g/1 mL) × (1 lb/453.6 g) = 257 lb
A solution has to have at least one solute, but there can be any number more than that. <span>There is only one solvent in any solution, whatever liquid is present in largest amount.</span>
