Determine how many pennies are in the stack on the left in the photograph at the beginning of this module. Create a conversion factor to calculate how many pennies are in the photo, knowing that there are 12 stacks of pennies.

How many peaks will be present in a mass spectrum for brcl?

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.

In general metals get as you move from left to right across the periodic table.
