What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
What is a positive test for an alkene?
A positive test for an alkene is the addition of bromine water, which will turn from orange/red to colorless when it reacts with the alkene due to halogenation of the double bond. This test is used to confirm the presence of alkenes.
What test distinguishes between alkene and alcohol?
Baeyer's test for unsaturation using KMnO4 . if the sol'n retains the purple color of the reagent , then it is an alkane. if the color disappears with formation of brown precipitate ,it indicates presence of unsaturated HC
What polymer is formed from alkene methylpropene?
Propane does not polymerize. Perhaps you meant propene, in which case the answer is "polyethylene, unless you're very clever." It's possible to make polypropylene from propene, but special catalysts must be used.
Which reactant was the limiting reactant in the vinegar lab?
Baking soda
What is the Use of everyday life in bromine?
it can be used to see if the hydrocarbon you have just cracked is an alkane or an alkene (it with turn orange to colourless if it is an alkene)
Which is one reactant used in photosynthesis to convert light energy into chemical energy?
carbon dioxide
What is one reactant used in photosynthesis to convert light energy into chemical energy?
carbon dioxide
What simple chemical test will distinguish an alkane from others?
Use bromine water (Br2) or acidified permanganate (H+/MnO4-) With permanganate: add the permanganate to the alkane and no reaction will occur, add the permanganate to the alkene and you will form a diol the solution will also turn from purple to colourless. With bromine water: add the bromine water to the alkane (plus you need sunlight) and you get a substitution reaction, this is a slow reaction. Add the bromine water to the alkene and you get an immediate addition reaction (this one does not need sunlight). When bromine water reacts with an alkene it is decolourised, the reddish brown bromine water turns from brown to colourless. This is because alkenes are unsaturated and contain a carbon to carbon double bond. If you did the bromine water test in a dark place say a cupboard then the alkene would decolourise but the alkane wouldn't because it needs UV/sunlight in order to react. in practice the cupboard is not necessary as the speed of decolourisation is so much faster with the alkene.
What is the meaning of fat hydrolysis?
Fat hydrolysis is the process of breaking down fats into its component molecules, such as fatty acids and glycerol, through the action of enzymes called lipases. This process occurs in the digestive system, where dietary fats are broken down into smaller molecules that can be absorbed and used by the body for energy or storage.
What is the reactant called that gets used up first?
The Limiting Reactant is the reactant that runs out first in a reaction.
Pharmaceutical uses of alkane?
The pharmaceutical use of alkane is often used in general anesthesia. Alkane is a compound of halothane which is a general anesthetic agent.
What is the difference between a limiting reactant and an excess reactant?
the limiting reactant is how much of a compound or solution you need to make an experiment possible. the excess reactant is the amount left over from the other compound or solution used (the other reactant that is used)
What is a positive test for an alkene?
A positive test for an alkene is the addition of bromine water, which will turn from orange/red to colorless when it reacts with the alkene due to halogenation of the double bond. This test is used to confirm the presence of alkenes.
the reactant that is completely used up in a reaction is called a?
Limiting reactant
What test distinguishes between alkene and alcohol?
Baeyer's test for unsaturation using KMnO4 . if the sol'n retains the purple color of the reagent , then it is an alkane. if the color disappears with formation of brown precipitate ,it indicates presence of unsaturated HC
