A chemist must prepare 500.0mL of hydrochloric acid solution with a pH of 0.50 at 25°C .
He will do this in three steps:
Fill a 500.0mL volumetric flask about halfway with distilled water. Measure out a small volume of concentrated ( 8.0M ) stock hydrochloric acid solution and add it to the flask. Fill the flask to the mark with distilled water.
Calculate the volume of concentrated hydrochloric acid that the chemist must measure out in the second step. Round your answer to
Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
