There are more red marbles than black marbles. We were able to address our hypothesis with the data collected because 26.32% of the marbles are red and just 14.47% are black. Also‚ the percentage of red marbles is the biggest in comparison with the others. The percentage of red marbles is very similar to the class average of red marbles. The percentage of red marbles is the highest in our group and the second highest in the class average. Also‚ the percentage yellow marbles is similar

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

The gas pressure sensor is used because the reaction produces oxygen gas. The faster the reaction is‚ the faster the pressure will increase. Thus‚ by examining the change of pressure overtime‚ the rate will be calculated and analyzed. For this investigation‚ the initial rate of the reaction is examined. Safety precautions All enzymes are potential allergens therefore eye and skin should be avoided Wear eye protection throughout the experiment and avoid rubbing eyes if the enzyme solution on hands

1/ Problem Statements: Our group has come up with some problem about “Chip and Bin” project: Techinical Failure: The system had electrical‚ mechanical‚ hydraulic and data faults that’s why it can’t be reliable. Lack of knowledge: Henderson and his team don’t know the project well and they also don’t understand their people so the people mistaking the purpose of the project as another method of the gorvernment to make them pay tax more. Lack of resource: The financing budget is not enough to make

COMBUSTION AND FIRE INVESTIGATION There are many different types of fires and it can be quite difficult to establish what may have started the fire in the first place. Fire investigation is an important process that attempts to establish the cause of the fire and whether a criminal act has taken place. The National Fire Statistics in the UK compiled by the Home Office states that 25% of fires are electrical in origin but this does not tell the whole story. The statistics are compiled from fire
