K_w is the equilibrium constant for the dissociation of water into hydronium ions (H3O+) and hydroxide ions (OH-) at 25°C. Its value is equal to (H3O+)(OH-), which is found to be 1.00 x 10^-14 M^2 at 25°C based on experimental evidence. Therefore, the correct answer is C, which represents this value in scientific notation.
