Question

Which of the following is not an information conveyed by a chemical equation?

• A.
  It conveys the names of various reactants and products
• B.
  It conveys the formulae of the reactants and products
• C.
  It conveys about heat change during the reaction
• D.
  
  It conveys how an element forms more than one compound

Answer 1

The correct option is D


It conveys how an element forms more than one compound
A chemical equation represents a chemical reaction. It conveys information about the heat released or absorbed in a reaction. The word form of equation contains the names of reactants and products while a chemical equation can also be written using the chemical formula of reactants and products. Reactants are written on the left-hand side of an arrow while products are written on its right-hand side. The arrow head points toward products. It does not give any information about how an element forms more than one compound.

Hence, the correct answer is option (d).
