Question

Which of the following information is not provided by the balanced chemical equation?

• A. Symbols of the compounds involved
• B. Number of atoms of each element
• C. Speed of the reaction
• D. Total mass of the substances on both sides

Answer 1

The correct option is C

Speed of the reaction

• A chemical equation is an equation in which all the reactants and products are represented by using their symbols or formulae.
• A chemical equation is said to be balanced if the number of atoms of each element on the left-hand side is equal to the number of atoms present on the right-hand side.
• A balanced chemical equation always follows the Law of conservation of mass that is - ‘mass can neither be created nor be destroyed. It can only be transformed from one form to another.’ Due to this, in a balanced chemical equation total mass of reactants is equal to the total mass of product.
