Acid gas

An unknown sample is identified using the relationship between the mass of the product and mass of the reactant in a balanced chemical equation using the involved species molar mass. THEORY The relationship between mass of the product and mass of the reactant taken directly from the balanced chemical equation and molar masses of the involved species is used in this experiment to find the mass of the unknown sample. In this experiment the unknown sample is found out ,which will be on of the following

DC Chemistry Co. Memo To: Oliver P. Bivalve, President of CBOFA From: John Student cc: Ms. Chemistry Teacher Date: March 24, 2017 Re: Chesapeake Bay Ocean Acidification Report The data from our experimental design supports the idea that the pH in the Chesapeake Bay is decreasing and becoming acidic. Our team used the following materials to test this idea: ● 3- 100 mL beakers ● 1 jar with a lid ● 1 graduated cylinder ● 1 mortar and pestle ● 50 mL of tap water ● 50 mL of seawater ● pH paper ●

AQA GCSE Chemistry Unit 1 C 1: Fundamental ideas: C 1.1. Atoms, elements and compounds: * All substances are made up of atoms. * Elements contain only one atom. * Compounds contain more than one atom. * An atom has a tiny nucleus in its centre, surrounded by electrons. C 1.2. Atomic structure: * Atoms are made up of protons, neutrons and electrons. * Protons and electrons have equal and opposite electrical charges. Protons are positively charged, and electrons are negatively

that has a chlorine odor (Sodium 2016). The manufacturers generally supply bleach as a dilute aqueous solution because it is extremely reactive and unstable.  Bleach will eventually decompose into a variety of by-products, such as oxygen, chlorine gas, and salt (Schueller 2014). To prevent this decomposition from occurring too rapidly, bleach should be stored away from light or heat. The active ingredient in sodium hypochlorite; consists of a negatively charged hypochlorite ion (CLO-) and positively

baking soda is sodium hydrogen carbonate.{Source 1} What does baking powder contain? It is made from an alkali, bicarbonate of soda, and an acid, cream of tartar, plus a filler like corn flour or rice flour which absorbs moisture. {Source 2} How does baking powder work? The powder is activated

1. What is hardness and what impact does it have on water quality? Hardness is the amount of dissolved calcium and magnesium in the water. Hardness impacts on water quality throughout the aesthetic acceptability by consumers (meaning the concentration of the calcium and magnesium and other dissolved solids are measureable by the consumers). In addition to, economic and operational considerations (which is controllable throughout the treatment or blending in public drinking water), hard water tends

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation

The unknown compound was solid at room temperature and was white. It was soluble in water, as indicated by Table 1. Of the list of possible known compounds, the unknown could not be CaCO3 or MgCO3 because neither one of those compounds are soluble in water, but it could have been any salt as the compound is ionic. From there, a conductivity test proved that the unknown compound conducted 1.1 volts of electricity, meaning the compound contained both positively and negatively charged ions that move

because the system is at equilibrium, it does not mean that the system is balanced and healthy. Whilst the Belmont Villas pool was at equilibrium, its levels for pH, alkalinity, free chlorine, combined chlorine, total chlorine, hardness and cyanuric acid were far below acceptable levels, and so many measures (as discussed above) must be undertaken in order to improve its health and make it safe and comfortable to swim in. However, this reaction is also linked to the pH of the system; as OH- is a product

fermentation reaction will occur faster?’ The experiment conducted was to measure the amount of C02 produced by the yeast going into fermentation, however varying the pH of glucose solution by using different pHs . To test this every 5 minutes the volume of gas in the test tube was observed and recorded until a period of 30 minutes had been. The end results Introduction Respiration is a chemical process by which organic compounds release energy. There are two types of respiration reactions that cells use
