Question

In a chemical equation if reactants are mentioned, then how we could find out what are the products ?

For example, A and B are two substances, participating in a reaction , so what will be the products of the reaction. i.e. A+B→?​

Answer 1

Answer:

The substance(s) to the left of the arrow in a chemical equation are called reactants. A reactant is a substance that is present at the start of a chemical reaction. The substance(s) to the right of the arrow are called products . A product is a substance that is present at the end of a chemical reaction. In the equation above, the zinc and sulfur are the reactants that chemically combine to form the zinc sulfide product.

There is a standard way of writing chemical equations. The reactants are all written on the left-hand side of the equation, with the products on the right-hand side. An arrow points from the reactants to the products to indicate the direction of the reaction:

reactants → products

When appropriate, a symbol may be written above or below the arrow to indicate some special circumstance. The symbol “Δ” is often used to indicate that the reaction is to be heated.

Answer 2

Answer:

1)Reactants are starting materials and are written on the left-hand side of the equation. Products are the end-result of the reaction and are written on the right-hand side of the equation.

2)B

△H=△E

If the  reaction involves products and reactants in solid/liquid in state then,△ng=0

△H=△E+(△n)gRT

△H=△E

So, B is the correct answer.
