(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

Design Lab #17: Reaction Rate - Calcium Carbonate & Hydrochloric acid Design D: Introduction: In this experiment calcium carbonate will be put into a flask and mixed with hydrochloric acid to produce calcium chloride‚ water and carbon dioxide. The formula for this reaction is: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) Purpose: The purpose of this experiment is to determine how the surface area of CaCO3(s) affects the rate of

Nuclear Chemistry: The Good vs. the Ugly The definition for nuclear chemistry is the application of chemical techniques to the solution of problems in nuclear physics. This includes the discovery of naturally occurring and synthetic radioactive elements and the results of nuclear fission. There are both pros and cons in nuclear chemistry. People believe that nuclear chemistry is bad for the environment but there are a lot of great things that can come out of this. Things like medical uses‚ food
