INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle. Once the aerosol particles are large enough, they become cloud droplets that will have a different mechanism of growing. Cloud droplets grow differently because they are larger in size. Instead, they grow by a new process…

Research question Even though Amylase can get denatured at high temperatures, a slight increase in temperature, should increase the rate of amylase reaction. Research title The effect of temperature on amylase activity. Word count-1025 Background research Enzymes are catalysts which speed up reactions in living organisms. Enzymes function by decreasing the activation energy for a reaction. Amylase is an enzyme found in human saliva and catalyses the hydrolysis of starch .Amylase…

In a chemical equation, there are the reactants, which is the part that is changed, and the products, which is what is left over. The reactant side and the product side must have the same quantity of each element. If they do not, the equation must be balanced by using coefficients. Mole ratios can be found by using these coefficients. Mole ratios are conversion factors and can be used to found the amounts of the reactants and the products in a chemical reaction. These can also be used to find…

Physics is everywhere. Especially in NASCAR which stands for National Association for Stock Car Auto Racing is a racing sport which the racing cars have motion. “NASCAR is motorsport's preeminent stock-car racing organization. The three largest racing-series sanctioned by this company are the Sprint Cup Series, the Xfinity Series, and the Camping World Truck Series.”(Mukul Bhatia.What is NASCAR?.www.quora.com.) On the rough racetrack nascar cars are made to be driven in extreme conditions. In…

This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

Ava Lilienthal Science Barcus 7-4 The Physics Behind Soccer Soccer really has a lot to do with science. From Newton’s laws of motion to the momentum of the person kicking the ball, the drag force and the magnus effect, and even the air pressure in the ball. It is harder than most people think. Next time you watch a soccer game, or play a soccer game, think about the science in the game. First, Newton’s Law’s are present when the ball is kicked. His first law, an object at rest stays at rest…

Prac 18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its…

Kinetic Energy and Potential Energy Math Exploration 2/14/2018 Part 1: Finding Kinetic and Potential Energy Directions: For each situation, you need to determine if the object has KE or GPE or both. Then find their values. Be sure to include the correct units. 1. A 2-kg bowling ball sits on top of a building that is 40 meters tall. Circle one: KE / GPE / both Show your work for finding the values of each type of energy the object has: The ball is not moving and is at a height above…
