FORMAL LAB REPORT INTRODUCTION John Dalton’s atomic theory states that elements combine in simple numerical ratios to form compounds. A compound‚ no matter how it is formed‚ always contains the same elements in the same proportion by weight. The law of mass conservation states that mass can neither be created nor destroyed. In this experiment‚ the mass of the metal was not destroyed or created; the metal’s mass was simply changed into a compound form once the gas

Factors Affecting the Rate of Enzyme Activity Justin Hunter G. Kim September 16‚ 2011 September 26‚ 2011 Abstract Catalase is a common enzyme found in nearly all living organisms that is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less reactive oxygen and water molecules. Catalase is a protein that is most commonly found in the liver. The purpose of this experiment was to determine the effect that changes in temperature and pH have on the function

It is essential and absolutely vital to exercise proper lab safety any time that a person‚ including yourself‚ is in the lab. One of the most important parts of remaining safe in a lab is wearing the proper clothing and equipment‚ such as goggles and an apron. It is also very important that everyone who is eligible to participate in a lab or is present in the lab is well-versed in the basic and general rules of lab safety. It is important to follow these rules so that everyone in the lab can avoid

the same ribbon and after being cut into lengths was stored in the same way in plastic containers. Preliminary - I originally did a preliminary test with Iron wool where we used a similar method but Test the iron wool was held over the flame by tongs and not contained within a crucible. We learnt from this experiment the importance of the crucible to contain all of the metal for an accurate test because the iron wool broke off as it heated and we were left with a lot of the iron wool on the bench
