OUTLINE 1. Intro- Chemical and biological weapons first appeared in a large quantity in the First World War. Chemical weapons‚ such as sarin‚ nerve gas‚ and mustard gas‚ have to be made in a laboratory. Biological weapons‚ such as Typhus‚ Q fever‚ and Anthrax‚ can be viruses or bacteria. Chemical and Biological weapons have few advantages and so many disadvantages that the advantages aren’t worth the possible effects. 2. Paragraph 1-advantages that can be turned into disadvantages a. Point 1-killing

WATERY WORLD Water Usage in HICs Agriculture (39%) – use water to irrigate crops‚ using automated machines that use lots of water. Industry (47%) – Water is used in production and for cooling. Some use 1million litres a day Domestic (14%) – piped water supplies used for baths (150L) and washing machines (100L) other Water Usage in LICs Agriculture (91%) – Less efficient and require man power. Water is wasted in evaporation. Industry (5%) – There is less industry‚ more small cottage shops

Rey Vincent P. Antonio Experiment 8: Quantitative Determination of Copper Concentration in Aqueous Solution by Iodometric Titration Results and Discussion Oxidation-reduction titration is a kind of volumetric analysis where the titrant used undergoes a redox reaction with the analyte. In this experiment‚ the oxidation of iodide (I-) to produce iodine (I2) is taken into consideration. The use of this concept in a redox titration is called iodometry. Iodimetry‚ on the other hand‚ deals with the

Properties of Gases General Chemistry 1 Lab 5 Abstract: The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame‚ O2‚ CO2‚ Air

3.09 Honors: Here is sample data and how you would do the calculations. Of course‚ you will need to use your data‚ but you can follow along step-by-step. In the lab‚ you must record the following measurements: mass of your empty crucible mass of your crucible and the hydrate (the original chemical) mass of the crucible and chemical after heating(which is the dehydrate) The other two in the data table are calculated (mass of hydrate and mass of dehydrate) SAMPLE DATA – YOU MUST USE YOUR
