Environmental Science (Assignment) JULY 31‚ 2013 1. What is a biome? A biome is an area of the planet that can be classified according to the plants and animals that live in it. Temperature‚ soil‚ and the amount of light and water help determine what life exists in a biome. It is different from an ecosystem. An ecosystem is the interaction of living and non-living things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many

because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited amount of product can form from given amount of starting materials. Limiting reactant in our case is the reactant which determines the amount of product generated in a chemical reaction. The objective of the experiment is to determine the limiting reactant in a salt mixture‚ and to determine the percentage composition of each substance in a salt mixture To better understand the concepts‚ we look at the reaction

have what Psychologist Carol Dwek calls a "fixed mindset versus a growth mindset." Or we could say some have a failure versus a success mindset. How can we help students to move from a failure to a success mindset? We must help them to change their limiting beliefs so that they are willing to allow themselves to succeed. For this to occur there needs to be more pain associated with failure than with success and more pleasure linked with success than with failure. Can pain actually be linked to success

Essay Utopia or Dystopia? The Giver describes a society in search of perfection‚ which is a recurring theme in literature. Somebody in Jonas’s society decided that eliminating or limiting choices and feeling‚ among other things‚ would ultimately create a perfect place in which to live. By eliminating and/or limiting choices and feelings‚ the creators were able to implement Sameness‚ which would then provide a conflict-less environment in which to exist. To most kids in our society‚ the changes

is produced‚ what is the percent yield of CO2? C6H12O6+6O2 → 6CO2+6H2O *__Calculate the theoretical yield__ –This problem has ‘’2 reactants’’‚ however‚ the limiting reactant‚ in this case‚ glucose‚ is already mentioned. This is because of the phrase ‘’”in excess of oxygen”’’. This means that oxygen is in excess‚ so C6H12O6 is the limiting reactant. So we convert the 45 grams of glucose to grams of CO2. 45 g C_6 H_12 O_6×(1 mol〖 C〗_6 H_12 O_6)/(180 g)×(6 mol 〖CO〗_2)/(1mol C_6 H_12 O_6 )×(44 g

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

Factors Affecting Enzymes The activity of an Enzyme is affected by its environmental conditions. Changing these alter the rate of reaction caused by the enzyme. In nature‚ organisms adjust the conditions of their enzymes to produce an Optimum rate of reaction‚ where necessary‚ or they may have enzymes which adapted to function well in extreme conditions where they live.Increasing temperature increases the Kinetic Energy. In a fluid‚ this means that there are more random collisions between molecules
