1. a) How do you represent chemical changes in chemistry?b) What should you know to write a chemical equation?c) How are reactants and products separated in a chemical equation?
Answers
Answer:
I am explaining it briefly.
Explanation:
a)In chemical changes are represented by equations.b)To write a chemical equation we should know the positions of reactants and products and we need to know how to balance a chemical equation and a arrow between the reactants and products.c)Reactants are at the left side of the arrow and products are at the right side of the arrow.
Answer:
a) Chemical changes in chemistry are represented by chemical equations.
b) We should know the formulae of reactants and products to write a chemical equation. Also, we should know to balance any chemical equation.
c) Reactants are written on the left hand side of the equation with a plus sign between them and products are written on the right hand side of the equation with a plus sign between them. There is an arrowhead between reactants and products written. The arrowhead represents the direction of the chemical reaction taking place.
