The alkynes are more acidic in nature as compared to the alkenes . This is due to the fact that the alkynes give hydrogen on reacting with sodium metal, but Alkenes don’t give hydrogen. The alkynes release hydrogen and forms a sodium salt which clearly shows it’s acidic nature.

Mechanical digestion :- In this type of digestion the food is broken down into simple particles in mechanical way , like chewing in mouth by teeth and churning of food in stomach by the muscular movements of the smooth muscles of stomach walls. Chemical digestion :- In this type of digestion the complex molecules of
No , melting of ice will not be a chemical change as it simply involves the change in the state of water. But during this change the colour, odour, taste , chemical or molecular formula will remain the same . And these all are the indications of physical change only.
The arrow in between the chemical equation is an important part of the equation. It depicts that the reactants are converted into products. Or in simple language we can say it shows the conversion of reactants into products. On its left hand side are the reacting species and on its right hand side are the
This is a type of reaction mechanism that is seen in case of nucleophillic substitution reactions. It is BIMOLECULAR NUCLEOPHILLIC SUBSTITUTION mechanism. In this kind of mechanism two molecules decide the rate of reaction, so it is BIMOLECULAR mechanism. The whole mechanism proceeds through a single step. That concerted step involves the bond breaking and
Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formed
This is a best example to share when we talk about chemical change, that the products have totally different properties from that of the reactants , from which they are made. Now coming to the answer, Formation of water is a highly exothermic type of reaction and a lot of energy is lost at the
Chemical Change The change which give rise to new substances with new properties that are totally different from the starting matter. 2H2 + O2 ———> 2H2O Chemical changes are normally accompanied by the following changes:- 1. change in state 2. Change in colour 3. Change in temprature 4. Evolution of gas Chemical reaction Representation
The need of balancing the chemical equation. The law of conservation of mass , “ Mass can neither be created nor be destroyed during any chemical change”. So the number of atoms on both RHS and LHS must be equal in the chemical equation. We have to check the total number of atoms on RHS
