In a water solution, how do acids differ from bases? a. acids form hydrogen ions (h+), while bases form hydroxide ions (oh–). b. acids turn litmus blue, while bases turn litmus red. c. acids form salts, but bases do not. d. hydrogen ions (h+) remain dissolved, but hydroxide ions (oh–) do not.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?
