PLANNING COURSEWORK- STARCH AND AMYLASE AIM The aim of this coursework is to investigate the effect of temperature change‚ on the rate of hydrolysis of starch catalysed by amylase. PREDICTION I think that as the temperature increases‚ the rate of reaction also increases‚ to a point when it dramatically decreases. On graph 1‚ you will see a sketch of the graph which I expect to be the result of the experiment. SCIENCE REASONING I think my prediction is correct because the rate of a

A double replacement reaction is a chemical reaction that usually takes place between two aqueous ionic compounds. In the reaction‚ the cation of one compound replaces the other compound’s cation that yields two produce two new and different compounds. A precipitation reaction is a chemical reaction in which the formation of a solid‚ as one of the products‚ arises “when two solutions are mixed”(Zumdahl‚ Decoste 184). This solid is also known as the precipitate of the reaction. One type of evidence

Question 1 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation where is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation where is Planck’s constant (). Note that frequency has units of inverse seconds ()‚ which are more commonly expressed as hertz (). Part A A microwave oven operates at 2.40 . What is the wavelength

Statistics Coursework Plan – In this project‚ I will be investigating how accurately students can estimate an angle size and the length of a line. I am investigating it to see if age‚ gender and mathematical capabilities have an effect on how accurate students can estimate a length of a line and an angle size. I will be using secondary raw data which is given to me to my teacher who has collected the data from other students. The accuracy of the data is unknown and also human errors are also
