Biology Lab Report Investigating the Relationship between Cell Size and Rate of Diffusion Ban Madi 11 Dp Biology SL Research Question: How does the size of the cell affect its efficiency in exchanging substances through several ways‚ like diffusion? Aim: To plan and carry out an investigation to show the relationship between volume/Cm3‚ surface area‚ and diffusion using agar cubes measured in time/s; and to demonstrate‚ using diffusion‚ why the size of cells is

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid) and

Alka-Seltzer Rocket Formal Lab Report Abstract In the Alka-Seltzer Rocket lab one was to experimentally determine how much (grams) Alka-Seltzer and water in mL‚ is needed to launch the rocket the highest/longest distance in cm. Also to experimentally determine the % NaHCO3 in the tablet using the information from the highest/longest distance. Calculate the error and % error of NaHCO3 in an Alka-Seltzer tablet and to determine the limiting reagent for the highest/longest distance traveled. Alka-Seltzer

Multistep Synthesis of Benzilic Acid The synthesis of several complex organic compounds follows a multistep synthesis. "Multistep synthesis" refers to the procedure in which the product of one reaction serves as the starting material in the subsequent reaction. The multistep synthesis of benzilic acid begins with a conversion benzaldehyde to benzoin through a condensation reaction. The benzoin then oxidizes into benzil‚ which undergoes rearrangement to give benzilic acid. Benzoin Synthesis * When

Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

An impressive story is about the sad fate of widows in India during the past century‚ before Ghadi’s ideas started changing India’s traditions. First of all‚ water is also the story of a people trapped in a hidebound culture that values tradition above basic rights and dignity for women. I was unaware of this issue‚ but this movie harshly questions a religion that imposed such a level of degradation upon women

will test the suggestion that the enthalpy change between a metal and a solution of a salt is related to the relative position of the two metals in the reactivity. Presumably the further apart in the series the bigger the enthalpy change will be. The experiment is as follows‚ 1) Zn(s) + CuSO4(aq) ZnSO4(aq) + Cu(s) 2) Zn(s) + Pb(NO3)2(aq) Zn(NO3)2 (aq) + Pb(s) Both of the solutions will be in 1mol.dm-3 Apparatus: Distilled Water Polystyrene Cup Polystyrene Lid

Chemestry Lab Rates of Reaction (Picture from: http://sciencespot.net/Pages/kdzchem.html) The rate of reaction is how fast or slow a reaction is completed. This is important for factories and chemists all over the world. What happenes during a reaction is atoms or molecules that collide and form new molecules. You can affect this rate of reaction with: temperature of reactants or suroundings‚ surface area of reactants‚ if there is a catalyst present‚ but in theis lab the concentration was changed
