A double displacement reaction is a type of chemical reaction in which two compounds react in order to create two new chemicals. The two cations and anions switch places with each other which forms two new compounds. As an example AB+CC can switch to AD+CB. Both sides of these equations must balance out in order to be neutral. So any pairs of compounds (such as A+B) must have a total balanced charge. In this example A could have a charge of positive 2 (+2) and B could have a charge of negative

Section 9-1 Review Key Ideas 1. Identify the primary source of energy that flows through most living systems The sunlight. Autotrophs use sunlight to make their own food. Organisms that can’t make their own food consumed the food molecules made by autotrophs‚ eat autotrophs or eat organisms that consumed autotrophs. 2. Explain how an organism’s metabolism is related to Earth’s carbon cycle. An organism’s metabolism is related to using energy to build organic molecules which contain

electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from the indicators used. The reactions showed that hydrogen ions were produced at the anode‚ making

Chapter 10 – Photosynthesis – Homework 1. Write the basic equation for Photosynthesis (Ps). 2. Some students define Ps as the process by which plants use light energy as food. Discuss if this is a correct statement that would likely be accepted by an AP Biology Exam Reader. 3. Contrast and compare an absorption spectra versus an action spectra for Ps. 4. Discuss why is the narrow area of electromagnetic radiation between 380-750 nm is the best choice to power a process like Ps

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely
