It has harmful effects on plants, animals and buildings. Acid rain is mostly caused by human emissions of sulphur and nitrogen compounds which react …

Beetroot samples: The same size beetroots will be used throughout the experiment this is to ensure that the impact of the temperature on every sample will stay the same, i.e. if having a bigger beetroot sample less pigments will be released into the test tube at lower temperature, or having …

Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by …

When testing urine the test results may provide information regarding the status of carbohydrate metabolism and kidney function. The kidney glomeruli act as ultrafilters for the plasma protein; however as much as 150 mg/dl of protein may normally be excreted into the urine. In glomerular proteinuria, an increase in glomerular …
