(Name) (Course Name) (Instructors Name) (Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited

permeable cell membrane allows the cell to regulates the exchange of materials in/out of the cell. Controls the internal environment of the cell. 4.) Would you expect osmosis and diffusion to stop when substances are evenly distributed? Support your answer. If there is no concentration gradient (when the substances are evenly distributed) there will be NO osmosis or diffusion. There will be movement across the membrane‚ because the molecules are always moving. This movement will be in equlibrium

In the 18th and 19th centuries scientists wrestled with identifying and describing the nature of the “stuff” that produced change. One concept that became popular for a while was that of “caloric” (what we now call heat). “Caloric was originally conceived of as a quantity that would flow from a hotter object to a cooler one that would warm up as a result. It answered the need for a way for the cause of warming to get from here to there. Not only did caloric serve as a cause for warming‚ it
