... In a synthesis reaction two or more simple substances combine to form a more complex substance. Two or more reactants yielding one product is another way to identify a synthesis reaction. For example, simple hydrogen gas combined with simple oxygen gas can produce a more complex substance----water! ...

... d. Correct. You might initially think that this is an incorrect representation; however, 12 g of C, 32 g of O2, and 44 g of CO2 each represent one mole of the substance, so the relationship of the chemical reaction is obeyed. e. Correct. The coefficients in balanced equations can represent amounts i ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
