Compounds Quiz 2

chemistry

 There is a mixture with different organic chemicals. Rahul is able to separate the organic chemicals from the mixture. Now the separated chemicals are called as ____

  Organic compounds contain more than one element in their composition with proper bonding.

The pure organic substances which are separated from the mixture of the different organic chemicals are called as pure compounds.  

Observe the following chemical reaction and answer the following question. ${{N}_{2}}+3{{H}_{2}}\to 2N{{H}_{3}}$ In the above reaction what is the nature of the ammonia?

 In any chemical reaction the product will be a mixture of reactants and it is called a compound not mixture.

In the chemical reaction nitrogen is going to react with ammonia and forms ammonia as a product. Then the product ammonia is called a compound not a mixture.

 Identify the wrong statement among the given options?

 Compounds contain different elements with perfect bonds in between them.

 Due to the absence of the bonds between the different compounds in a pure substance in the chemicals compounds can be easily separated using chromatographic techniques. 

There is a chemical A and converts to B and B converts to C. Again the formed chemical C converts to A. The cycle is never stoppable. <img src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/171a3063-d65e-4b44-9405-fd898bee24ef8710757654998552434.png"/> Then at Time ‘T’ Sandhya tested the reaction mixture with thin layer chromatography and found a lot of spots on the TLC. Then the reaction always contains?

 If there are more than two chemicals that exist together and have different properties then the chemical is called mixture.

 At any point of time during the given chemical reaction there is always a presence of three chemicals A, B and C. Then the reaction always contains mixture. 

Observe the below image and answer the given question.<img src="https://cmds-vedantu.s3.ap-southeast-1.amazonaws.com/prod/question-sets/8c9798e2-b514-4b7a-b1c3-a3ca464f6c004405075123981038817.png"/> The chemicals which are present in box B and D are?

 Compounds contain the same chemical formula throughout the composition.  

 The chemical which contains the same chemical composition throughout the chemical is called compound and the chemical contains different compounds is called mixture.
