In an acid-base titration, how would you monitor the progress of the experiment and know when it was completed? A. Continue the reaction until you have added an equal volume of acid to the base.
B. Add 1 ml of acid at a time to the base and monitor with pH paper until it is neutral.
C. Use indicator solution which changes color when enough acid is added to react with all the base.
D. Place a thermometer in the flask and continue adding acid until a temperature change is noted.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.

Apump contains 0.5 l of air at 203 kpa. you draw back on the piston of the pump, expanding the volume until the pressure reads 50.8 kpa. what is the new volume of the air pump
