The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

17 October 2012 Early American History Reaction Paper A Reaction in American History The History of America interests not only me‚ the world on a grand scale. America was a form giver to many of today’s governments looking at what we did in the past things that if you looked upon them today you would say that these are just normal things‚ but in the time period this happened this is nowhere near normal‚ it’s abnormal. Population growth‚ mannerisms‚ transportation‚ a split country

Stoichiometry of a Precipitation Reaction March 20‚2013 Amber McCollum Introduction Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist among the reactants and products in chemical reactions To predict the amount of product produced in a precipitation reaction using stoichiometry‚ accurately measure the reactants and products of the reaction‚ determine the actual yield vs. the theoretical yield and to calculate the percent yield. The equation

Columbus‚ the man who discovered the new world‚ infact did not discover it‚ for it was inhabited by migrants from Asia‚ more than fifteen thousand years ago‚ almost one thousand years before Columbus landed in America. Christopher Columbus was‚ despite the arguments a Genoan man and infact Christian‚ and he had two brothers and a sister. He sailed a thirty-three day trip on his first voyage and ‘found’ America on October twelfth. But‚ before this‚ Columbus had to go through the queen in order to

Title: Stoichiometry of a Precipitation Reaction Purpose: The purpose is to predict the amount of precipitation using stoichiometry. Another purpose is to measure and calculate percentage yield. Procedure: 1. Weigh out 1.0g of CaCl2*2H2O and put it into a 100mL beaker. 2. Add 25mL of distilled water and stir. 3. Using stoichiometry to determine how much Na2CO3 is needed for a full reaction. 4. Weigh the calculated amount and put it in a small paper cup. Add 25mL distilled water and stir

Kaily Purtle 09-10-2012 Study of the Family Reaction Paper 1 In class we discussed Reading #4. This reading was about the “Super Mom”. We discussed our personally experiences along with readings. We talked about how stay at home mothers and working mothers get looked at by society and by their husbands. I will be writing my reaction paper on this topic because it is very interesting to me. The “Super Mom” is described in the White and Klein text as a “stroller in one hand‚ brief

This is one thing that the two lead characters in the movie do not contain over themselves. They both made sacrifices just to be able to have the title of the one who has the greatest magic trick. They sacrificed their friendship‚ their families‚ even their lives. Before they started their rivalry‚ they both have good relationship with each other‚ good family‚ a

an endothermic reaction (heat is on the reactants side where the solid is). Increasing the temperature would result in stress on the reactants side from the additional heat. Le Châtelier’s Principle predicts that the system would shift towards the product’s side in order to alleviate this stress. By shifting towards the product’s side‚ more of the solid is dissociated when equilibrium is again established - which equates to increased solubility. Second‚ imagine an exothermic reaction (heat is on the

Department of Chemistry Chem 180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write
