For Herbert Run the conductivity level was 687µS/cm. The Turbidity level was 0 FAU and the Nitrate level was 0.02ppm. I accept my hypothesis and reject parts of my hypothesis. I reject that both streams have a high turbidity level. Both streams’ turbidity level is zero.
The molar heat of combustion of a compound is 1250 kJ/mole. If 0.115 moles of this compound in a bomb calorimeter with 2.50 L of water, what would the temperature increase be? If change in heat is positive it is an _______ reaction If change in heat is negative it is an_______ reaction
This lab uses a lake simulation to study how the addition of nutrients and toxins can affect the lake, its inhabitants and the surrounding area. There is a strong focus on the addition of Phosphorous and added toxins because both are key elements in growth in lakes. The Virtual lake includes these five simulated species; green algae, cyanobacteria, bosmina, daphnia, and trout. There are two types of phytoplankton in the lake model, green algae and cyanobacteria. Green algae are a very diverse group that are photosynthetic, aquatic, plant like organisms that have a very simple reproductive structure.
The Article “Finding Flow” by Mihaly Csikszentmihalyi, expresses the choice we have in life to live or die until the end of days. He shows how we take control of our own destiny, and to not let distractions get in the way of our accomplishment. Csikszentmihalyi portrays that everyone has a different idea of accomplishment and goals, but living life to the fullest is shared by many. By saying this he means don’t waste your potential by letting side issues get in the way. In the article Csikszentmihalyi mentions a study held in a factory where most welders hated their jobs and found no passion in it.
1. What was your theoretical yield and your percent yield? Theoretical yield: 3.9151 g Percent yield: 79.30% 2. An accurate percent yield must be below 100% Why?
During the process of incineration, the waste materials are converted into ash while producing gases and heat, which can be used to generate electricity. Among various methods of burning waste, incineration comes with several benefits. First of all, incineration reduces the mass of waste by approximately 95%, thus making it a better alternative in comparison to dumping into landfills, considering the current shortages of land. Also, when people are disposing of possibly life-threatening waste such as used medical materials, incineration is more beneficial as toxins can be destroyed with high temperature. Thus, incineration is a popular solution to treat waste materials especially in European Union countries such as Sweden and
During this time, rises in the demand of coal-powered steam engines led to a rapid increase of coal mining (Wrigley 54). As the evolution of the market system took place, the small scale techniques that the industry had been using were not supplying a sufficient level of coal output needed to maintain the high demand in the manufacturing and transportation sectors. This deficiency prompted a transition for the coal mining industry that involved dangerous mining techniques and labor
Since we were using up a massive amount of coal each year, we would have less cleaner air, a chance of the smoke in the air to start forest fires, and many other variables that would come into play. Also, using coal for multiple machines in a factory can be very hazardous. The machines could malfunction, causing an overload in energy which could end in an explosion. The air in the factory would also be basically fatal if not wearing the right protection. And if not using things like airlocks (which they didn’t have) it could spread to outside air and then animals would breath in the toxic air then die.
When it reaches the ignition temperature, the heat decomposes some of the cellulose material and is released as volatile gasses (Harris). The gasses then react with the oxygen around and make heat. The heat then keeps the fuel at ignition temperature, so it won’t go out until no heat is present or until the fuel runs out (Science Learning Hub). The heat from the reaction is what people feel when sitting next to a campfire. When a fire ends, there is no fuel left to burn, and all the un-burnables are left (ash), and the carbon (Harris).
Water seeps from the basin up to the surface through cracks in rocks. This water pools in shallow water tables, creeks, springs and rivers that all provide permanent water sources in the dry and inhospitable desert (“Great”). It has been known for many years that there is coal far underneath the basin, but it is of low grade. For many years, mining companies have begged for access to the deserts coal fields, but it was denied because it was not economically or environmentally feasible (“The”). With fossil fuels on the decline, however, the demand for access is getting higher.

Coal is a dark black mineral that is formed by dead plant matter that is crushed over millions of years of heat and pressure underground. When coal is burned, the sunlight stored from those ancient plants photosynthesis is released. The energy from coal is used to generate electricity in Fossil fuel power plants. Although natural gas and petroleum can be used in this type of power plant, coal is the most commonly used. The design is somewhat similar to a nuclear plant.
In coal there is energy, this energy is stored until it's activated . Coal gets its energy from old plants and swamps from millions of year ago. So basically all coal is or is made up of is old organic material and the energy is stored in this rock which we call the rock it forms coal. Coal also if you think about it is a fossil but without the visual impression. Coal mining is such a big industry and that is because of its industrial properties .
Experiment No.1 Objective: To balance a rotating mass (disturbing mass) with a same mass (balancing mass) rotating at equal radii in the same plane Related Theory: Balancing of Rotating Masses: The process of adding the second mass in order to counteract the effect of centrifugal force of first mass is what we call as balancing of rotating masses. Why Balancing is Required
When surface water (H2O) reacts with sulphide minerals in coal heaps or exposed coal rocks it chemically reacts to produce acidic water such as sulphuric acid (H2SO4). STUDENT No. 48494070 STUDENT NAME: NOBLE KANYERA UNIQUE No. 603854 5 ASSIGNMENT 02
