What are Greenhouse Gases? These are the gases that make up our atmosphere: Carbon Dioxide 89% Methane 7% Nitrous Oxide 3% Halocarbons 1% What is the Greenhouse Effect? The Greenhouse Effect is the way that gases in the atmosphere trap heat from the sun. They let heat in‚ but prevent most of it from escaping. It is essential for life because we need a certain amount of radiation to heat up our atmosphere. What human activities produce Greenhouse Gases? By burning fossil fuels such as coal‚ oil and

Burns There are many different types of burns. Within those types there are three degrees: first‚ second‚ third‚ and fourth. Fourth degree burns are not recognized by all professionals so only first‚ second‚ and third will be covered here. The most common‚ or basic‚ types of burns are from overexposure to the sun‚ exposure to heat such as fire‚ and chemical burns. For each degree of burn there are different treatments and procedures on how to deal with the burns properly. Third degree burns

Fire Protection Systems There are several types of fire extinguishing systems. They are wet‚ dry‚ chemical and gaseous types of systems that can be implemented. The type of fire and the circumstance that created it will dictate which methods are the best‚ safest and most efficient ways to extinguish a fire. Examples would be kitchen fires‚ grease fires in particular are difficult to extinguish with water and sometimes counterproductive to extinguishing the fire. Wet chemical systems are most

An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples

Noah Stewart-Maddox Chem 121 10/12/11 Synthesis of Potassium Ferric Oxalate Trihydrate and The Determination of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In

okay love youAcidified potassium manganate(VII) is a strong oxidising agent so it can be used to oxidise substances. If a reaction occurs a colour change will be seen. Potassium manganate(VII) is deep purple and when it is reduced‚ it becomes colourless. Let’s take a look at some reactions involving acidified potassium manganate(VII). If a solution of potassium manganate(VII) is placed in a test tube and a light green solution of iron(II) chloride is added to the test tube‚ the purple colour of

Rotary Kiln is Widely Used in the Ferrous Metallurgy Industry. In the process of Beneficiation‚ Rotary Kiln can be used for the magnetizing and roasting of lean iron which turns its previous weak magnetism to strong magnetism and is good for beneficiation. According to various types of the ore‚ there are different roasting methods for the magnetizing and roasting such as reduction roasting‚ oxidation roasting‚ reduction & oxidation roasting‚ and neutral roasting. The most used reducing agent
