    Answer:

    For a: The balanced equation is 2S(s)+3O_2(g)\rightarrow 2SO_3(g)

    For c: The balanced equation is 2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)

    Explanation:

    A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

    • For (a):

    The given unbalanced equation follows:

    S(s)+O_2(g)\rightarrow SO_3(g)

    To balance the equation, we must balance the atoms by adding 2 infront of both S(s) and SO_3 and 3 in front of O_2

    For the balanced chemical equation:

    2S(s)+3O_2(g)\rightarrow 2SO_3(g)

    • For (b):

    The given balanced equation follows:

    2Al(s)+3Cl_2(g)\rightarrow 2AlCl_3(s)

    The given equation is already balanced.

    • For (c):

    The given unbalanced equation follows:

    2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+H_2O(l)

    To balance the equation, we must balance the atoms by adding 2 infront of H_2O(l)

    For the balanced chemical equation:

    2NaOH(s)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+2H_2O(l)

    • For (d):

    The given balanced equation follows:

    C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)

    The given equation is already balanced.
