Abeaker with 175 ml of an acetic acid buffer with a ph of 5.00 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 5.60 ml of a 0.470 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.760. express your answer numerically to two decimal places. use a minus (- sign if the ph has decreased.

How is electrolysis most commonly used to produce an energy source? a - splitting water molecules produces oxygen, which organisms breathe to fuel their bodies. b - splitting water molecules produces hydrogen gas, which is used to power machines through hydrogen fuel cells. c - splitting carbon dioxide molecules produces coal, a form of carbon that can be burned to produce heat. d - splitting carbon dioxide molecules produces natural gas, which can be burned to generate electricity in power plants.
