The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the

Periodic Table: * Mass Number = protons + neutrons in the nucleus * Atomic Number = number of protons in the nucleus * Number of neutrons = mass number – atomic number Example: Lithium (Li) * # of protons + # of neutrons = mass # * 3 + 4 = 6.9/ 7 * The atomic mass is the mean of all the isotopes of Lithium in nature; round the number * Isotopes of a specific element have a varying number of neutrons * The number

The chloride shift is basically an exchange of chloride ions through the capillaries of the system circuit. In the blood plasma‚ there is large amount of carbonic acid and when there is an increase in carbonic acid than the balance of hydrogen ions and carbonate ions dissociate to maintain a balance of homeostasis in the pH of the blood. The red blood cells help to maintain this system by buffering the system of carbonic acid and causing detachment of the above ions. The release and detachment is

mole ratio. Introduction The objective of the Get Charged Up lab was to determine the charge on a metal ion reacting with HCl by determine the mole ratio in a reaction by determining the amount of excess reactant‚ amount of product‚ and amount of hydrogen gas produced as well as finding the best research method to determine the charge. To accomplish this‚ three different methods were used. Titration was used to react NaOH with HCl to determine the amount of H+ left over after the reaction is complete

RED is taking its knowledge of high-quality cinema cameras to the smartphone industry with a new product. The Hydrogen One is RED’s bet to revolutionize the use of smartphones. Back in 2006‚ when RED was founded and showed its intent on delivering high-performance digital cinema cameras with quality of 35mm film and the convenience of pure digital‚ many people were skeptical and some even considered it a “scam”. After a 10-years background of providing unique high-quality cinema cameras with high-usage

Method – PG 5‚ 6‚ 7 Preliminary – PG 7 Actual experiment and graphs – PG 7+ Chemistry coursework Hypothesis/Aims The aim of the investigation is to see how different concentrations of hydrochloric acid affects the rate at which hydrogen gas is produced when it’s reacted with a strip of magnesium. The rate of reaction is a measure of change that happens in a single unit of time. When a reaction takes place the particles of the reactants collide. The more often the particles collide

Hydrocarbons play a key role in our daily life. You must be familiar with the terms ‘LPG’ and ‘CNG’ used as fuels. LPG is the abbreviated form of liquified petroleum gas whereas CNG stands for compressed natural gas. Another term ‘LNG’ (liquified

For example: Mg + 2HCl Mg + H2SO4 MgCl2 + H2 MgSO4 + H2 I discovered from an A’ level text book (A-level Chemistry by Ramsden) that nitric acid doesn’t usually give hydrogen‚ but may do with magnesium if the acid is cold and dilute. The book didn’t say how dilute the acid had to be. Other products may include oxides of nitrogen. I know that some acids are weak and some are strong. A strong acid is one which ionises fully in solution to give hydrogen ions and‚ for example
