    Which of the following illustrates the Law of Conservation of Mass?  (Please use a capital letter)A.  +  B. + + C. + + D. +

    Explanation
    The Law of Conservation of Mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products. In option C, there are two reactants represented by the "+" signs and two products represented by the "+" signs. This demonstrates that the mass of the reactants and the mass of the products are equal, thus illustrating the Law of Conservation of Mass.

    True or False: The subscript can sometimes be changed and the coefficient can always be changed.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because in a chemical equation, the subscript represents the number of atoms of a particular element in a molecule and cannot be changed without altering the identity of the compound. On the other hand, the coefficient represents the number of molecules and can be changed to balance the equation, as long as it is done proportionally for all the elements involved.

    Balance the following equation.  Make sure to put commas between your numbers.  Put the numbers in order from left to right. ____ + ____

    Correct Answer
    2,2, 2, 2
    Explanation
    The equation is asking for the balanced form of the given chemical equation. The numbers provided after the equation represent the coefficients that need to be added to balance the equation. In this case, the equation is already balanced as it is written. The answer of 2,2, 2, 2 indicates that there are 2 of each element on both sides of the equation, resulting in a balanced equation.
