Determining the Limiting Reactant and Percent Yield in a Precipitation Reaction Objectives: Observe the reaction between solutions of sodium carbonate and calcium chloride. Determine which of the reactants is the limiting reactant and which is the excess reactant. Determine the theoretical mass of precipitate that should form. Compare the actual mass with the theoretical mass of precipitate and calculate the percent yield. Materials: Balance 0.70 M sodium carbonate solution‚ Na2CO3(aq)

Conclusion…………………………………………………………………………....…….8 Works Cited ………………………………………………………………………………..9 Properties of Enzymes and Competitive Inhibitors. Abstract: Properties of enzymes were found in this experiment and some other factors‚ which affect enzyme activity. Enzymes are catalyst; they catalyze very specific reactions. Results relating to the active site of specific enzymes played a big role while performing this experiment. The purpose of this experiment was to fin how inhibitors affect

Introduction: Temperature - Is a measure of the motion of particles‚ increasing the temperature will cause the particles to move faster because the reactant particles have more thermal energy from the heat. When particles move faster‚ more frequent collisions will occur and the collisions are more violent. This should increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more

huge amounts of energy‚ and their molecules are spread out as much as possible. With very little pressure‚ when compared to liquids and solids‚ those molecules can be compressed. It happens all of the time. Combinations of pressure and decreasing temperature force gases into tubes that we use every day. You might see compressed air in a spray bottle or feel the carbon dioxide rush out of a can of soda. Those are both examples of gas forced into a smaller space than it would want‚ and the gas escapes

Temperature Rising Global Warming is the increase in the average temperature of the Earth’s near-surface air‚ landmasses‚ and oceans its projected prolongation. Many believe that the Earth is currently facing warming in the ozone layer brought on by the rising levels of trapped gases known as the greenhouse effect resulting especially from pollution. Global warming is‚ in Laymen’s terms‚ altering the balance in energy of the earth (Reid 27). “The topic of climatic change has been in question

Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction affects by substrate

each species is adapted to certain conditions the climate of a region is an important factor in determining which organisms can survive there. Even within a biome‚ precise conditions of temperature and precipitation can vary over small distances. Ecologists recognize at least ten different biomes. The world’s major biomes include tropical rain forest‚ tropical dry forest‚ tropical savanna‚ desert‚ temperature grassland‚ temperate woodland and shrub land‚ temperate forest‚ northwestern coniferous forest
