Maya, a student, performs a titration. she completes the following steps as part of her titration procedure. 1. she cleans and rinses a burette with base solution. 2. she fills the burette with standardized base solution. 3. she adds a base from a burette to an acid. 4. she observes a color change in the erlenmeyer flask. 5. she continues to add more base. based on the above procedure, will she obtain accurate results? yes, because the more base there is, the better the results will be. no, because she initially contaminated the burette with base. yes, because she used a standardized base solution in the burette. no, because she did not stop adding base once the color changed.

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.
