Question

reactant और product क्या है? उदाहरण सहित बताये|

Answer 1

Answer:

reactants are the substances/compounds/elements that react or combine to give products.

products of the substances that are formed after the reaction of two or more substances / elements / compounds.

eg. Na + O2 --------- Na2O

Na and O2 are reactants and Na2O is the product formed.

Answer 2

In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can’t change one element into another in a chemical reaction — that happens in nuclear reactions. Instead, you create a new substance with chemical reactions.

A number of clues show that a chemical reaction has taken place, for example:

Something new is visibly produced

A gas is created

Heat is given off or taken in

Chemical equations show the reactants and products, as well as other factors such as energy changes, catalysts, and so on. With these equations, an arrow is used to indicate that a chemical reaction has taken place. In general terms, a chemical reaction follows this format:
