in a similar setup to the equilibrium lab, you place the fulcrum at the 25 cm mark on a uniform meter stick with mass 150g. Then you hang a mass #1 of 75 grams at the 62.5 mark, a mass #2 of 25 grams at the 12.5 cm mark, and an unknown mass #3 at the 0 cm mark. Draw a free body diagram and find the value of mass #3 in order for the system to be in equilibrium

In a similar experiment to the one you have performed a student is measuring the equilibrium for an organic acid that is soluble in water and in cyclohexane, a nonpolar organic solvent. When shaken with the solution of water and cyclohexane, it distributes between the organic and aqueous phase. The two phases are separated and titrated with 0.12 M NaOH. Calculate the equilibrium constant for an acid where the titration of the aqueous phase requires 9.9 mL of the base...

A 12 cm by 25 cm by 36 cm box of cereal is lying on the floor on one of its 25 cm by 36 cm faces. An ant, located at one of the bottom corners of the box, must crawl along the outside of the box to reach the opposite bottom corner. What is the length of the shortest path? (* note: the ant can crawl on any of the 5 exposed faces (not the bottom, which is flush...
