The restriction on the use of wood applicator sticks in a chemical reaction should be explained. Concept introduction: A chemical reaction is a process that results in the chemical transformation of one type of substances to another. The substances that are initially involved in the reaction are called reactants. The new substances that are formed after the occurrence of the reaction are known as products. The general equation to represent a chemical reaction is as follows: aA + bB → cC + dD Where, A and B are the reactants. C and D are the products. a and b are the stoichiometric coefficients of reactants. c and d are the stoichiometric coefficients of products.

Answer 1

Question

Definition Definition Number that is expressed before molecules, ions, and atoms such that it balances out the number of components present on either section of the equation in a chemical reaction. Stoichiometric coefficients can be a fraction or a whole number and are useful in determining the mole ratio among the reactants and products. In any equalized chemical equation, the number of components on either side of the equation will be the same.
