Chemical equation

classified into two categories: (a) balanced chemical equations or (b) mathematical-based equations and graphs. Balanced chemical equations are traditionally used to support student understanding of the overall, complex reaction under study in the experiment or simulation. Balanced chemical equations are also used to support a mechanistic understanding of the step-by-step process of reactants turning becoming products. Here, balanced chemical equations illustrate the creation and consumption of reaction

Objective: The purpose of the lab was to see if when two compounds were combined a reaction would occur. If the reaction did occur we wrote a balanced chemical equation of the products and reactants with the correct solubility rule. Safety: • wear protective eye goggles • have long hair tied up • wear close toed shoes • Wear correct clothes(not baggy) MSDS safety precautions: 1. Sodium Carbonate (Na2CO3): Sodium Carbonate is harmful when it is inhaled. It can cause irritation when touched to

This energy is stored in sugar. The chemical equation for photosynthesis is 6CO2 + 6H2O ------> C6H12O6 + 6O2. Photosynthesis supports almost every organism in some way. The sugar that chemical energy is stored in can be transformed into ATP, the fuel that powers the majority of living things, through cellular respiration. (Farabee

off light and heat. Burning is a chemical change for new substances are created that cannot changed back are formed. Oxygen is needed for combustion or also called rapid oxidation. When oxygen is added, it causes a fire to burn hotter and faster. In this lab both wood and steel wool were burned in pure oxygen and air. Wood is mixture of many substances but for this lab we will focus on the cellulose aspect for the chemical equation. Cellulose has the same chemical formulation as sugar of C6H12O6

respiration converts into ATP (Farabee, 2010). The chemical equation for photosynthesis is: 6〖CO〗_2+ H_2 O→C_6 H_12 O_6+ 〖6O〗_2 There are two stages to photosynthesis. The first stage of photosynthesis is a set of reactions typically referred to as the light-independent reactions (Damon, 2007). The light-independent reactions predominantly involve photosynthetic pigments (including chlorophyll) absorbing light energy and undergoing a conversion into chemical energy known as Adenosine Triphosphate (ATP)

For this experiment, a series of strong acid-strong base titrations were performed to determine the unknown solution concentration of HCl. KHP was first titrated with NaOH in order to create a standardized solution of NaOH. This solution was used to titrate a known volume of the unknown 1 HCl solution. The results were then used to determine the exact concentration of the original HCl sample. One thing that could be changed during this lab is to use a more neutralized sample of deionized water. Throughout

The goal of this experiment was to use conductivity to evaluate the number of ions in a chemical equation to confirm that the Law of Conservation of Matter is true both in theory and practice. The original hypothesis was that the experimentally determined ions and number of moles would indeed give the same results as the Law of Conservation of Matter, and that the predicted volume of acid needed to completely react with barium hydroxide would be 12.5 mL. This hypothesis has been proven in that the

Ionic Reactions Abstract This experiment is designed to study the nature of ionic reactions, and write net ionic equations for precipitation reactions, as well as to identify spectator ions, perception reactions and solubility of different compounds. Experiment and Observations In this experiment I was using a 96-well plate to add two drops of the following solutions into seven wells in rows A through E: cobalt (II) nitrate, copper (II) nitrate, iron (III) nitrate, barium

Most of the reactions took time to settle down to form a precipitate as seen in Diagram (1) which shows the before and after of magnesium hydroxide. Discussion: Chemical Equations for the reaction between cations and anions Na2CO3 + Mg(NO3)2 -> MgCO3(s) + 2NaNO3 Na2CO3(aq) + Ca(NO3)2(aq) ---> CaCO3(s) + 2NaNO3(aq) Sr(NO3)2(aq) + Na2CO3(aq) ===> SrCO3(s) + 2NaNO3(aq) Ba(NO3)2 (aq) + Na2CO3 (aq) ==> 2NaNO3 (aq) + BaCO3 (s) Chromates Calcium nitrate Ba(NO3)2 + Na2CrO4 --> 2 NaNO3 + BaCrO4 Barium
