17. (1 point) which of the following is not an empirical formula? * sb₂s₃ c₂h₃o becr₂o₇ c₂h₆ 18. (1 point) which of the following is not true about empirical and molecular formulas? * the molecular formula can be a whole number multiple of the empirical formula. the molecular formula of a compound can be the same as its empirical formula. the empirical formula of a compound can be twice the molecular formula. several compounds can have the same empirical formula, but have different molecular
17. C2H6 is not an empirical formula because it is not simplified all the way down to a simple ratio of the number of atoms.
18. The empirical formula of a compound can be twice the molecular formula The empirical formula is the simplest ratio of atoms in a compound, so it cannot have be a larger multiple of a ratio than the actual molecular formula of that compound.
Answer from: Quest
they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
Answer from: Quest
What are the options? physical property can be color, smell, opacity, viscosity, density, infra red spectrum, melting and boiling points, attraction and repulson to magnets, etc.

Which element is the least metallic between cadmium, silver, zinc, or iron?
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.
