Lalin Candium Lab Report Chemistry Block H Mr. Neil Chipman Calculating the Atomic Mass for Different Candium Isotopes Objective: In this experiment I will be discovering the atomic weight of Candium isotopes. By doing this experiment‚ it helps us to know how to calculate the relative abundance and atomic mass of each Candium isotopes without having to use the spectrometer. This lab will achieve my understanding of isotopes and why it has different masses but same number of protons due

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

unknown acid‚ which returns to being clear. However‚ after more NaOH base was added to the unknown acid solution‚ the solution eventually turned pink after swirling the flask. Data processing: As we did not refill the burette with NaOH each time after titrating the unknown acid‚ we need to calculate the difference of the volume before and after each titre. For example‚ the volume used in the first titre would be calculated by: 25-21.3=3.7 mL Uncertainty: (Uncertainty of the previous volume

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

truth is the sole purpose of philosophy". Clearly‚ we are in deep water on this topic. Some believe in absolute truth‚ while others believe truth is relative. I believe truth is not absolute when it comes to the names of physical things. Nevertheless‚ I do believe truth is absolute when it comes to moral things. Aside from those‚ I believe that God is absolutely true. First‚ from the time someone is born to their death‚ every human is taught what their parents and other people from years before
