Balancing Chemical Equations! Trivia Questions Quiz
Settings
Chemical equations include chemical formulae that represent all substances that are involved in the reaction. When it comes to balancing chemical equations, proper attention must be given to both reactants and product sides of the chemical equation. The rule of balancing the equation is making sure that the number of moles on both sides is equal. Do you know how to balance chemical equations?
