You are asked to prepare 500. ml of a 0.100 m acetate buffer at ph 5.00 using only pure acetic acid (mw=60.05 g/mol, pka=4.76), 3.00 m naoh, and water. answer the following questions regarding the preparation of the buffer.1. how many grams of acetic acid will you need to prepare the 500 ml buffer? note that the given concentration of acetate refers to the concentration of all acetate species in solution.2. what volume of 3.00 m naoh must you add to the acetic acid to achieve a buffer with a ph of 5.00 at a final volume of 500 ml? (ignore activity coefficients.)3. pour the beaker contents into a 500 ml volumetric flask. rinse the beaker several times and add the rinses to the flask. swirl the flask to mix the solution. add water to the mark to make the volume 500 ml. stopper the flask and invert how many times to ensure complete mixing?

Juju.01) 5 geologic events a group of students designed an experiment in an ice rink to represent the solar system. the steps of the experiment are listed below. 5: geologic events 1. choose a student to represent the sun. the planets are represented by two tennis balls. 2. ask the student to hold the tennis balls in each palm and spin on the ice with arms stretched out. 3. ask the student to draw in the arms after about 10 spins. 4. observe the student's arms rotate faster when they are closer to the body. 05 geologic events enors) the experiment most likely demonstrates that (2 points) 07 discussion-based sessment/module planets exert gravitational force on the sun the sun exerts gravitational force on the planets 3.07 discussion-based ssessment speed of a planet depends on its distance from the sun new version available!
