Calculate the pH of a solution containing:
a) 0.0500 M methanoic acid and 0.100 M sodium
methanoate. (K, =1.6 x 10-4 mol dm-3)
b) 0.0100 M benzoic acid and 0.0400 M sodium
benzoate (Ka = 6.3 x 10-5 mol dm-3).
c) 0.100 M ethanoic acid and 0.200 M sodium
ethanoate (pK, ethanoic acid = 4.8)​

Ammonium perchlorate nh4clo4 is the solid rocket fuel used by the u.s. space shuttle. it reacts with itself to produce nitrogen gas n2 , chlorine gas cl2 , oxygen gas o2 , water h2o , and a great deal of energy. what mass of nitrogen gas is produced by the reaction of 2.1g of ammonium perchlorate?

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.

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.
