Almost there o well tomorrow is another day

But alkenes also turn bromine water colorless much faster than alkynes. http://www.bbc.co.uk/schools/gcsebitesize/science/ocr_gateway_pre_2011/carbon_chem/5_making_polymers2.shtml

Anyway goodluck to the winner. Tomorrow is another day.

Time for today's winner to be declared.
i suggest you continue with calculation related courses. this will eliminate possibilities for searching google

A. A compound is substance which contains two or more elements chemically combined together e.g water while a mixture contains two or more constituents which can easily be separated by physical method.


B. Alkyne

@ProlificEric,both alkene and alkyne are unsaturated hydrocarbons that decolourise bromine water and besides, there are numerous delineating parameters to distinguish between a compound and a mixture. I call for a re-evaluation. Thank you.

QUESTION 4
(a)What do you understand by the term separation technique and what is the main importance of separation technique?
(b)Mention the separation techniques in the right order invoved in the separation of a mixture of sugar and sulphur.
Re: closed by Rickcutie(m): 10:09am On Feb 19, 2017
Remember no space booking, post the correct and complete answer when u've got it. Half answer will earn you nothing.

Re: closed by omoosun39(m): 10:10am On Feb 19, 2017
Separation techniques are method which can be used to separate the component of a mixture
Re: closed by Rickcutie(m): 10:11am On Feb 19, 2017
Whatever you post first is what will be used. If you edit your answer later, it won't count.

seperation technique is a method used to separate two mixtures from each other
2.usage of filter paper
Re: closed by DrAuthentic: 10:12am On Feb 19, 2017
Separation technique is a method employed to sort or segregate compounds or mixtures into its component elements. The importance is to separate out the component elements and fractions present in the mixture, dissolution in water will dissolve sugar and filtration will filter undissolved sulphur. Evaporation will recover sugar from the filterate

1- Seperation techniques refers to the methods implore in the Seperation of mixtures taking advantage of qualities different boiling point, different solubility, different melting point e.t.c.

2-crystallization-->Precipitaion--->Filtration.

(b)Mention the separation techniques in the right order invoved in the separation of a mixture of sugar and sulphur.

(a)Separating technique is a method taken to recover individual constituents of a mixture.
(b) filtration, evaporation
Re: closed by IamLucy(f): 10:15am On Feb 19, 2017
DEFINTION:seperation technique is a method of technique used in seperating two matters such as liquid &solid


IMPORTANCE:
separation technique is important because it helps chemists(even students) analyze the substances being under consideration.


METHOD:
Simple disolution
Filtration
evaporation
Re: closed by faradexs09(m): 10:15am On Feb 19, 2017
1. Separation techniques are method used to separate two imiscible substance with different physical properties...b) the aim of separation techniques is to achieve a Pure substance with no impurities

2. A) dissolution of the mixture B) filtration of sugar from the sulphur c)Evaporation of water d)recrystallization of the sugar e)drying of the sulphur

Re: closed by Nobody: 10:17am On Feb 19, 2017
1. Separation techniques are the procedures by which the individual componets of mixtures are separated.
The importance is to obtain a particular element or compound from the mixture.

2. By dissolution in water, followed by filtration, and evaporation of the sugar solution.
Re: closed by keandre: 10:19am On Feb 19, 2017
separation techniques is a method used to separate mixtures or different substances .
The importance of separation techniques is applicable in industrial production used by scientists, chemists to evaluate, analyze various chemical or industrial mixtures.

B. Dissolution, filtration and evaporation
