Which of the following statements is(are) true?

l type='a'>

  • A balanced equation relates the numbers of molecules of reactants and products (or numbers of moles of reactants and products).
  • i>To convert between moles of reactants and moles of products, we use mole ratios derived from the balanced equation.

    i>Often reactants are not mixed in stoichiometric quantities (they do not run out” at the same time). In that case, we must use the limiting reactant to calculate the amounts of products formed.

  • When a chemical reaction occurs, it must follow the law of conservation of mass.
  • Interpretation Introduction

    Interpretation:

    The true statements amongst the given should be determined.

    Concept Introduction:

    A balanced chemical reaction is a reaction where the number of each type of atoms remains the same on both sides of an equation. Mole is a constant number which is used to quantify a number of molecules used in a chemical reaction. In order for a chemical reaction to proceed the minimum requirement is that the species involved must have the relative molar ratio represented in the balanced equation. Having an excess of moles of one or more reactant would not halt the reaction process when the relative molar ratio between the entities are already satisfied.

    Explanation

    Reason for true statement

    Because atoms are not changed or destroyed in a chemical reaction according to one of Dalton’s premises in his atomic theory one must make sure that the same number of each type of atoms exists in both sides of a chemical reaction.

    To find the number of product molecules formed or the number of reactants consumed one could rebalance the chemical equations such that you have the desired number as the coefficient. (Remember that stoichiometric coefficients are the smallest possible set of integers one could use to achieve balancing).

    It is true that one need to mix the reactants in the molar ratios derived by the stoichiometric coefficients in order for a reaction to proceed. However by adding additional amount from one or more species would not stop the occurrence of the reaction.

    Because atoms are not changed or destroyed in a chemical reaction according to one of Dalton’s premises in his atomic theory one must make sure that the same number of each type of atoms exists in both sides of a chemical reaction. This also ensures that the mass of the entities involved in both sides remain the same which gives rise to the law of mass conservation...
