High school students should have to complete mandatory community service to graduate. In this day and age, many students are unaware of the hard work that goes into balancing a job and going to school. In high school, you need a minimum of 40 hours of community service in order to graduate. I believe that students in secondary school should have to complete mandatory community service in order to graduate because it helps give back to the community, adjusts students…...

A chemical change is any change that results in the formation of new chemical substances, In the following experiment, a solution that begins with copper nitrate II will undergo a series of chemical changes. Examples of evidence for a chemical change include temperature change, color change, precipitate formation, and gas given offl During a change of temperature, a solution is exothermic meaning there is an increase in the speed of molecules. Exothermic is the taking in of energy When a…...

If I had the power to change something I would change the fact that everyone only cares about what you look like. I feel as if that is a very demeaning opinion, but never the less an opinion. People just say things about you and don’t really know who you are inside.

The reactant an enzyme acts on is referred to the enzyme’s substrate. The enzyme will combine with or to its substrate. While the two are joined, the substrate is converted to its product by catalytic action of the enzyme. There is an active site of the enzyme molecule which is a restricted region that actually attaches to the substrate. Usually the active site is formed by only a few of the enzyme’s amino acids, the rest is just the framework…...
Hess’s Law Of Heat Summation
Words • 1411
Pages • 6
Hess’ Law of Heat Summation Hess’ Law states that: “The enthalpy change for any reaction depends  on the products and reactants and is independent  of the pathway or the number of steps between  the reactant and product”. BASICALLY:    Hess’ Law states “the heat evolved or absorbed in     a chemical process is the same whether the process     takes place in one or in several steps”     ­­;This is also known as the “law of constant heat summation”. All it means is that no matter how many steps the chemical     reaction proceeds through, the total heat evolved or absorbed    is the added heat values of each step and will always be    a constant figure for that process. For example:     When phosphoric acid (a tri­hydrogen acid) is neutralized     with a base, the hydrogens are neutralised in 3 steps:    STEP 1:   H3P04 + NaOH ­; NaH2PO4 + H2O ­gives X amount of heat     STEP 2:   NaH2PO4 + NaOH ­; Na2HPO4 + H2O ­gives Y amount of heat    STEP 3:   Na2PO4 + NaOH ­; Na3PO4 +H2O ­gives Z amount of heat    Therefore, the total heat of reaction (   Hrxn) is equal to: Law Of Constant Heat Summation There are two (2) ways to calculate the heat of reaction  using Hess’ Law: 1­  Equation Method (Algebraic Method) 2­  Heat of Formation Method (Summation Method) Equation (Algebraic) Method Strategy:    ­add equations for reactions with known enthalpies     so that their net result is the desired reaction Sample Problem 1: Use the equations below to determine the enthalpy of reaction for the decomposition of hydrogen peroxide: H2O2(l)         H2O(l)    +    1/2 O2(g) The equations are: 1­    H2(g)   +   O2(g)       H2O2(l)    2­    H2(g)   +   1/2 O2(g)      H2O(l) Hf = ­188 kJ Hf = ­286 kJ Solution: Sample Problem 2: Use the following equations: 1­    1/2 N2(g)   +   3/2 H2(g)       NH3(g) 2­    1/2 N2(g)   +   O2(g)     NO2(g) 3­    H2(g)   +   1/2 O2(g)     H2O(g) Hf = ­46. 0 kJ Hf = +34. 0 kJ Hf = ­242. 0 kJ to calculate the enthalpy of reaction for: 4 NH3(g)   +   7 O2(g)        4 NO2(g)   +   6 H2O(g) Solution: Practice Problem: Calculate the heat of reaction for the oxidation of one mole of ethanol to ethanoic acid: C2H5OH(l)   +   O2(g)         CH3COOH(l)   +   H2O(l) Use the equations below: ­    C2H5OH(l)   +   3 O2(g)          2 CO2(g)   +   3 H2O(l) 2­    CH3COOH(l)   +   2 O2(g)         2 CO2(g)   +   2 H2O(l) Hc = ­1367 kJ Hc = ­874 kJ Enthalpy of Formation  (Summation) Method Standard Molar Enthalpy of Formation: (             ) ­the amount of ____ (absorbed or released) when _________ of   a compound is formed from its _________________ in their  standard states ­most enthalpies of formation are ­ve (__________________)? therefore, most compounds are ___________ stable than the  elements they are made from…...

The following example essay on "Enzyme Catalase" describes a substance that catalyzes the decomposition of hydrogen peroxide formed during biological oxidation into water and molecular oxygen and is found in almost all organisms, and is involved in tissue respiration. Enzymes are proteins that function as biological catalysts (Perry, Morton 2007). They maintain the body’s stable internal balance, and without them life would be impossible (Sullivan, 2013). Enzymes are capable of speeding up reactions that otherwise would happen at a slower…...

In this lab, our task is to determine how different degrees of temperature affect reaction rates. A Swedish chemist, named Svante Arrhenius discovered the relationship between temperature and reaction rate. In finding this relationship a new equation was formed called the Arrhenius Equation: Reaction rate constant k = A e -Ea/RT The factor A represents the frequency of collisions between two molecules in the proper orientation for reactions to occur. The value of A is determined by experiment and will be different for…...
