Saturated oils are oils where every carbon is sp3 hybridized and attached to two other carbons and two hydrogen. An unsaturated oil features a pi bond and a sigma bond between one or more carbons. This sigma bond interacts with Br2 by way of an addition reaction, the double bond is broken and two bromine are added to the carbon chain. The resulting structure is colorless so in a way the oil absorbs the colored Br2 into a colorless molecule. So, the more Saturated an oil is, the more Br2 it can accept and that's why Br2 can be used to detect the presence of satiated oils. While adding Br2, the solution will stay colorless as long as there are double bonds to accept it.
Hope this makes sense, if you've talked about reaction mechanisms this should be pretty straightforward.
Answer:
The website is inaccurate.
Explanation:
Remember, a chemical change is characterized by many things, but most commonly:
- A change in color, temperature or state.
- An irreversible change
- One or more new substances are formed
Rusting (Iron oxide) is a redox reaction (Oxidation-Reduction Reaction) where iron molecules come in contact with water and oxygen molecules. The iron molecules lose electrons, becoming oxidized, while oxygen gains electrons, becoming reduced.
Is rust reversable? (No)
Did the colour of the iron on the surface change? (Yes)
Did a new substance form? (Yes, Read above).
Hope I helped! Have a good day!
Answer:
2 tall 2 short.
Explanation:
If 1 is tall, and 1 is short, 50% would be tall, and the other 50% would be short.
Answer:
Explanation: A mixture of two partially miscible liquids
Answer:
Arts and science are similar in that they are expressions of what it is to be human in this world.
Explanation:
Both are driven by curiosity, discovery, the aspiration for knowledge of the world or oneself, and perhaps, as the conceptual artist Goshka Macuga said on her recent visit to Cern, a desire for world domination.
