Is the mass of the reactants always equal to the mass of the products in a chemical reaction?
1 answer:
Answer: Yes, the mass of the reactants always equal to the mass of the products in a chemical reaction.
Explanation:
In a balanced chemical reaction, the mass of reactants is always equal to the mass of product that is a chemical reaction follows follows 'Law of Conservation of Mass'.
The law states that ' in a chemical reaction mass can neither be created nor be destroyed.
For example:
Mass of the reactants = Mass of products
36 amu = 36 amu
Yes, the mass of the reactants always equal to the mass of the products in a chemical reaction.

Answer: The IUPAC name of is 5-chloro-2-pentyne
Explanation:
1. First select the longest possible carbon chain. For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
2. The longest possible carbon chain should contain all the bonds and functional groups.
3. The numbering is done in such a way that the carbon containing the functional group or substituent gets the lowest number. Triple bond is given priority over substituent halogen.
4. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne.
Thus the IUPAC name of is 5-chloro-2-pentyne
