Is diamond a compound give evidence?
No, it is a crystalline form of carbon. Evidence? On chemical analysis, it contains nothing but carbon. Diamonds can be made from carbon.
What is a unsaturated compound?
An unsaturated organic compound is one which has double or triple bonds in Carbon atoms. When all the bonds are single then the compound is called saturated. In unsaturated compounds the carbon atom will be in sp or sp2 hybridised state and in saturated compounds the carbon will be in sp3 hybridised state. Unsaturated compounds are identified by the reaction with bromine water which is pink in color. The pink color is lost due to addition of Bromine to the multiple bond. Aromatic compounds like benzene also contain double bonds but not considered as unsaturated. They do not give addition reactions under normal conditions.
Is hydrobromic acid a compound or a element?
It is definitely a compound. It is a combination of two elements, viz. hydrogen(H) and bromins(Br) to give the chemical formula ' HBr '.
Which compounds will give you a positive bromine test?
Alkenes and alkynes will give a positive bromine test. The reddish-brown color of a bromine solution will be decolorized upon reaction with an alkene or alkyne due to the formation of a colorless dibromo compound.

Is sugar a physical property or chemical?
Sugar is a chemical compound. It is a carbohydrate that consists of carbon, hydrogen, and oxygen atoms. Its structure and composition give it certain physical properties, such as being sweet and soluble in water, but overall it is considered a chemical substance.
Why cant Br react with sulphuric acid to give Br?
If pure bromine is contacted with sulfuric acid, the only possible source of bromine atoms for a potential chemical product is the original bromine itself; the sulfuric acid does not contain any bromine atoms and therefore can not supply any additional atoms to make more bromine.
Give the name of CO2?
CO2 is the chemical formula of carbon dioxide.
Empirical formulas describe the types of atoms in a compound and their?
An empirical formula give information about the chemical composition of a compound. Example: tetracycline with the empirical formula C22H24N2O8 has the following composition: - carbon 59,44 % - oxygen 28,81 % - nitrogen 6,30 % - hydrogen 5,45 % If you're with plato the answer is ratios
