First recognized as a chemical compound in 1818‚ hydrogen peroxide is a clear‚ colorless liquid most often used for cleaning or disinfecting(Britannica‚ 2013). Since pure hydrogen peroxide is unstable‚ it is found in stores as an aqueous solution. The chemical formula for hydrogen peroxide is H₂O₂ which means there are two hydrogen atoms and two oxygen atoms in the compound(Liebeskind‚ 2013). Seed germination is simply the process in which a seedling sprouts from a seed and begins it’s growth. The

Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3 Na2CO3 + CO2 + H2O 2NaHCO3 Na2O + 2CO2 + H2O Variables: Independent: Original

Conclusion Both Kool Aid and Gatorade contain buffers. For the buffer in Kool Aid‚ pKa1 ≈ 3.70‚ pKa2 ≈ 4.90‚ pKa3 ≈ 6.50 and for the buffer in Gatorade‚ pKa1 ≈ 4.50‚ pKa2 ≈ 5.40‚ pKa3 ≈ 6.70. Discussion of Theory A buffer capacity is the maximum amount of hyrdrogen or hydroxide ion that can be added to a buffered solution before a significant change in the pH occurs. Increasing the concentration of the buffer can increase the buffer capacity of a solution. At the half equivalence point‚ the moles

The glow sticks can operate by causing two chemicals to mix. A common reaction used for these devices is hydrogen peroxide and phenol oxalate ester. The hydrogen peroxide is kept in a thin‚ small glass vial in the middle of the stick‚ and the second chemical phenol oxalate ester is in the main body of the light stick. Bending the light stick in the middle causes the small glass vial of hydrogen

Chemistry Catalyst Report Aim I am trying to investigate the effect of the mass of magnesium dioxide used on the speed of the reaction of 2H2O2(aq) 2H2O(l) + O2(g). I hypothesize that the speed of the reaction is proportional to the rate of decomposition. Independent Variable The mass of MnO2 used Dependent Variable The rate of decomposition through the amount of mass lost Controlled Variables Environment of the experiment Stay in the same place to carry out the experiment and finish the

muscles need ATP (ATP is a ‘energy currency’) most of these cell reactions rely on the breakdown of ATP the ways to get atp are to react anaerobically or aerobically. The “ reactions form energy in the format of ATP’’ ATP (also known as adenosine tri-phosphate) is produced. Respiration is conducted from the cell membranes inside the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose

Phosphate Fertilizers Market By Active Ingredient Published on 19th April 2014 Phosphorus is an essential nutrient required for plant growth. It helps in root development‚ plant maturation‚ and seed development. Together with nitrogen and potassium‚ phosphorus is one of the most important elements for plant life. These features make phosphorus essential to maximize the production of grains and forage. Modern farming is dependent on the use of inorganic fertilizers that contain phosphorus. Commercial
