Does knowing the ratio of masses of the elements in a compound lead to the unique chemical identity of the compound? O A. No, because more than one compound can have the same ratio of masses of elements, if the atoms are arranged differently. OB. No, because a compound can have different ratios of masses of its elements, depending on its source. C. Yes, because a molecule of any compound is composed of a whole-number ratio of atoms of its elements, per the law of definite proportions. D. Yes, because each compound has a unique ratio of masses of its elements.

SC Score: 0 of 1 point Incorrect Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. Steam reforming of methane (CH4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. An industrial chemist studying this reaction fills a 75.0 L tank with 14. mol of methane gas and 5.8 mol of water vapor, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 2.3 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits.
