PRELIMINARY CHEMISTRY ASSESSMENT TASK 1. Identify the sources of pollution which accompany the combustion of organic compounds and explain how these can be avoided. Combustion refers to the burning of a substance in oxygen. It is a process in which a self-sustained chemical reaction occurs at temperatures above those of the surroundings. Combustion of organic compounds can result in detrimental impacts on the environment such as the generation of acids and production of carbon monoxide, particulates and soot.
Secondly, gunpowder is a big component of New Years and the fourth of July celebrations. Fireworks are used to entertain groups of people, resulting in a mind blowing event. Lastly, gunpowder is also used as a war remedy, to cauterize wounds and such. Gunpowder is used for several different essentials and they were all great uses for it. Initially, gunpowder made several changes through history, starting with making the state of warfare completely different.
The plasma furnace is the central component of the system where gasification and vitrification takes place. Plasma torches are mounted at the bottom of the reactor, they provide high temperature air (i.e., almost three times higher than traditional combustion temperatures) which allow for the gasification of the waste materials. The gas produced in the furnace system is referred to as synthesis gas. This gas then enters the synthesis gas cleaning system. Gas cleaning refers to the process of removing acid gases, suspended particulates, heavy metals and moisture from the synthesis gas prior to entering the energy recovery system where power, steam and synthetic fuels can be obtained.
Fossil fuels like the substance sulfur dioxide products are burnt to heat water under pressure , making them steam. This high pressure steam is used to spin the turbine generators which make electricity although this method is not really used anymore now. 5.) What are the potential hazards for using this resource? The potential hazards for using sulfur dioxide is it can affect our environment, plants, animals, the air that we breathe, our water resources and our planet.
The teacher provided the following chemical equation to describe the burning, or combustion, in the candle: Hydrocarbon fuel + O2 ( CO2 + H2O The candle we used was a small, white emergency candle about 3.5 cm tall. The candle had already been used by someone else because I could see from the black wick that it had been lit before. When we lit the candle I noticed that at first it was only the wick that was burning. Eventually, after the flame
Thermal decomposition of carbonates Introduction: Carbonates decompose when they are heated, producing calcium oxide and carbon dioxide. Carbon dioxide can be detected using lime water. Calcium carbonate calcium oxide + carbon dioxide CaCO3 CaO + CO2 Other metal carbonates decompose in the same way. Here are the equations for the thermal decomposition of copper carbonate: copper carbonate copper oxide + carbon dioxide CuCO3 CuO + CO2 Hypothesis: some metal carbonates decompose more easily than others when they are heated. Aim: The times taken for a chemical reaction to take place metals high up in the reactivity series (such as calcium) have carbonates that take a lot of energy to decompose them.
Class B fires are those that involve flammable or combustible liquids and gasses. Using foam is one of the main ways to control a Class B fire. Class C fires involve energized electrical equipment that must be de-energized; for instance, a burning electrical generator. Once the object is de-energized in most cases the fire can be handled like a Class A or B fire. Class D fires or combustible metals that burn at extremely high temperature levels, and most metals cannot be put out with just water and dry powers are
These amusing rides attract all different types of people. Its trilling nature what makes rollercoasters the main attraction at most amusement parks. Most rollercoasters are known as big thriller rides, and are many fans’ favorites. People from near and far visit Six Flags for the sole purpose of getting a chance of riding these high flying attractions. Lines are usually very long for high intensity rides, but the anticipation that is created waiting in lines are a thrill itself.
While experimenting the possible used of gunpowder, the first rocket was born. Another positive outcome of the invention of black powder is fireworks. Fireworks are used every year to bring joy to the holiday seasons. For example, the Fourth of July and the New years are two of the many events where people of all kinds are brought together to celebrate and enjoy a firework show. To produce the aerial spray of reds, golds and blues, they would pack a tube with gunpowder, colorizing chemicals and small pellets that create the shimmer and the verity of shapes for the
The energy in the radiator is transferred to the air. Explain the factors that affect the rate of energy transfer in the engine and radiator. • The rate of energy transfer depends on the temperature difference between the system and the surroundings • Bigger the temperature differences between the radiator and the air, faster the rate of energy transfer. • Radiator contains water which has a very high specific heat capacity. So it can absorb a large amount of heat from the engine • Both the radiator and engines are made of metal which makes both of them good conductors of heat.
