An organic compound (cahbncodcle) was synthesized and a sample of it was analyzed and found to
contain only c, h, n, o, and cl. it was observed that when a 0.150-g sample of the compound was burned, it
produced 0.138 g co2 and 0.0566 g h2o. all the nitrogen in a different 0.200-g sample of the compound was
converted to nh3, which found to weigh 0.0238 g. finally, the chlorine in a 0.125-g sample of the compound
was converted to cl- and by reacting it with agno3, all the chlorine was recovered as agcl. the agcl, when
dried, was found to weigh 0.251 g. calculate the weight percent of each element in the compound.

How might this scientific phenomena be explained? a paper clip floats on water.

The sum of the oxidation numbers in a neutral compound is always

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 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
