Carbon Essays

Research Questions: 1. What is the optimal temperature for yeast to metabolize sugars? 2. What is the sugar that is most readily metabolized by yeast? Are there any sugars that yeast cannot metabolize? 3. What is the optimal concentration of sugar (in 60 mL of water) for yeast? Results: The …

Introduction Many yeasts are anaerobic organisms or can survive in oxygen – absent environments during which time they ”switch” to a process called anaerobic respiration for the purpose of producing food by breaking down carbohydrates. The final products of the anaerobic respiration are nutrients, ethanol and carbon – dioxyde. Whats …

To make a circuit board clamp 2 main modern materials are used, these are: * Low carbon steel * Nylon These two materials have many different properties and design issues and in this essay I am going to be looking at what they are and why that certain material has …

Aim: The aim of this experiment is to investigate into the effects of the change of carbon dioxide concentrations on the rate of photosynthesis. Prediction: My hypothesis is that as the concentration of carbon dioxide increases the rate of photosynthesis will also increase. Graph showing the effects of carbon dioxide …

Copper has two oxides, Cu2O and CuO. Copper carbonate, CuCO3, decomposes on heating to form one of these oxides and an equation can be written for each possible reaction. Equation 1: 2CuCO3 (s) > Cu2O (s) + 2CO2 (g) + 1/2O2 (g) Equation 2: CuCO3 (s) > CuO (s) + …

I have been given a solution that contains between 1.1g and 1.3g of iron ions; they are in a mixture of both Fe2+ and Fe3+. My aim is to work out the percentage of each of them in the solution. With my research I have found out that the best …

Alkenes also known as olefin is an unsaturated hydrocarbon which contains at least one carbon-carbon double bond. The general formula for alkene is CnH2n. Alkenes are insoluble in water but are soluble in orgainic solvent. The presence of double bond between carbon-carbon atoms is a strong link. However, the second …

Background Objectives (i) To be sensitised about the judicious use of energy fossil fuels. (ii) To think and suggest ways of conserving fossil fuels. Fossil fuels which are one of the basic sources of energy for all our activities are exhaustible. For example, coal, kerosene, and LPG are sources of …

The energy consumption grows year by year with the economical development of the countries such as China and Japan despite the boisterous events. With the ‘Arab Spring’ in 2011, energy market was shook in terms of both production and consumption of the oil with the loss of one of the …

Catalytic converters are used in cars to reduce pollution and toxic gases, such as carbon monoxide. Here are the reactions that happen inside a catalytic converter: 2NOx(g) → xO2(g) + N2(g) – this is the reduction of nitrogen oxides. 2CO(g) + O2(g) → 2CO2(g) – this is the changing of …
