Concentration vs Rate of reaction Brandon Introduction A reaction rate is the speed at which a chemical reaction will occur. Heat‚ concentration of a chemical‚ Surface area or a catalyst‚ will affect the rate of reaction. The concentration of a chemical will speed up of the reaction because the reactant particles have become more crowded therefore increasing the chance of productive collisions. In this practical the chemicals will be Sodium thiosulphate and Hydrochloric acid which will produce

reactant between Aluminum and Copper (ll) Chloride. Using stoichiometry‚ we were able to make predictions. Through the reaction 2Al + 2CuCl₂ → 3Cu + 2AlCl₃ we carried out this experiment and determined that the limiting reactant was CuCl₂ and that the aluminum was in excess. We also determined the percentage yield of copper. Purpose: The purpose of this experiment was to determine the limiting reactant and percentage yield of the reaction that took place between Copper (ll) Chloride and Aluminum.

Copper wire with Nitric Acid Objective: In this experiment‚ we’re going to find what will happen if we put the piece of copper wire in the Nitric Acid. And what type of reaction will occur. Materials: Test tube Graduated Cylinder Test tube rack Copper wire Beaker Nitric Acid Test tube holder Observation: 1. The color of the Nitric Acid is similar in the color

Alka-Seltzer Reaction Rates Lab What are the different factors the effect the reaction rate of Alka-Seltzer? Matthew Arkfeld Leah Gilligan Jessie Abbott Period 4 June 2nd‚ 2008 Background Research: o The objective of the experiment was to determine if different factors affect the reaction rate of Alka-Seltzer. Alka-Seltzer provides fast relief to acid indigestion‚ upset stomach‚ heartburn‚ headaches‚ body aches and pains. It is an antacid and pain relief medicine used by millions

we will study is called copper chloride hydrate. We first drive out the water‚ which is called hydration. This occurs if we gently heat the sample to a little over 100*C. The compound formed is anhydrous (no water) copper chloride. If we subtract its mass from that hydrate‚ we can determine the mass of the water that was driven off‚ and using the molar mass of water‚ find the number of moles of H2O that were in the sample. Next‚ we need to the find either the mass of copper of chlorine in the anhydrous

From the results recorded it was identified that activity A and C had exothermic reactions‚ whilst activity B had an endothermic reaction. Each of the activities had initially begun with 23.4/8/9oC‚ however‚ within one minute of adding the 2nd reactants‚ the results began showing‚ as seen from the graph. Activity A and C had risen in temperature‚ with A gaining 4oC and in total of 2 minutes having the temperature of 27.9oC along with C increasing by 2.2oC and within 2 minutes of the experiment having

seem to be caused by adverse drug reactions to medical drugs‚ according to research. On the contrary‚ Philippines don’t have a high risk of deaths that causes these because here in our country‚ we rely on those alternative medicines or herbal medicines. It is a lot cheaper but actually‚ it doesn’t have those therapeutic claims so it has a minimal assurance of being treated with the sickness. With these‚ we choose to use Western Medicines as well. Adverse Drug Reaction (ADR) is the response of our body

Concentration‚ Along with Varying Temperature and pH-Balanced Environments on the Enzyme-Catalyzed Reaction of pNPP Abstract: Introduction: Many of the chemical reactions‚ which take place in in living things are controlled by enzymes. In such cases‚ the enzyme is a protein in the cell which lowers the activation energy of a catalyzed reaction‚ which serves to increase the rate of the reaction. Alkaline phosphatase is made throughout the body. Its function is to remove phosphate groups

The cost to buy a metal will be affected by how abundant the metal is. The more abundant a metal is‚ the less it will cost. This is because less time and money will be needed to find economically viable deposits of the metal. Example: The cost of Copper has increased due to a decline in availability. b The cost of production of a metal‚ which includes mining the ore and then refining it to obtain the final product‚ will affect the price of the metal‚ because the more costly it is to turn the ore

Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction between an unknown ester and water
