A certain liquid X has a normal boiling point of 127.70 ° C and a boiling point elevation constant Kb = 2.41°C*kg*mol⁻¹ A solution is prepared by dissolving some iron(III) chloride (FeCl₃) in 700 g of X. This solution boils at 129.4°C . Calculate the mass of (FeCl₃) that was dissolved.

The answer is:   [d]:   "ultraviolet" {"  uv  "} .

The surface of the water droplet is held together by the attraction between molecules. in order for water to flow more easily into these small spaces, you need to decrease its surface tension. you can do this by adding soap, which is a surfactant (a material that decreases the surface tension of a liquid).

The answer your looking for is that both valance is 1 because they are both in the alkali group

I'm guessing its b crude oil
