1. What are the values for the pH, POH, [H+], and [OH-] for a solution made by mixing 10 mL of 1.5 HCl (a strong acid) with 10 mL of 1.2 M NaOH (a strong base)? (Hint: Determine the volume for the equivalence point first and then figure out if you are before or after the equivalence point)​

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.

Can you me with this i really appreciate it

Ants live on acacia trees in south america. the ants feed on sugars secreted by the trees. the trees provide room for the ants to live. the ants sting any other insect or animal that comes to eat the trees. what type of relationship is this?
