how do you make a chemical equation more informative?
Answers
Answer:
(a) The various ways in which a chemical equation can be made more informative are : (i) By indicating the physical states of the reactants and products. Example: Gaseous state is indicated by the symbol (g). (ii) By indicating the heat changes taking place in the reaction.
Chemical equation can be made more informative by writing the following additional information to it
➜Information regarding temperature pressure catalyst etc . is provided Above and below the arrow. separating reactants and products .
➜The reaction which are reversible can be shown by the sign of reversibility .
➜Heating during the reaction can be shown bed sign of delta over the arrow.
➜ Physical states of reactants and products can be provided by using the letters as for solid l for liquid G or upward Arrow for gas and aq for solution in water .
➜Chemical reactions proceed with evolution or absorption of heat .This information is provided by adding the term heat .
➜Concentration of acids can also be added to the reaction .
➜Any reaction in which a precipitate is formed the precipitate can be represented by a downward arrow .
