PLEASE HELP If the radio waves transmitted by a radio station have a frequency of 90.5 MHz, what is the wavelength of the waves, in meters?

Write the chemical formula for a compound that is made of an element from group 1 and an element from group 17

Answer explain why it is not possible to deduce a complete order of reactivity.

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.
