Results: Since the mass of the ball bearing used in this experiment was very light‚ 20 balls were measured and the result was divided by 20 for better accuracy. This procedure was repeated for the sizes and the results are as follows: Diameter (mm) Mass (kg) 2 0.04 3 0.075 4 0.11 To find out the densities of the three balls‚ the following formula was used: Density= (mass of the ball)/(Volume of the ball)= mass/(4/3 π r^3 ) Density of 2mm ball = (0.04⁄1000)/(4/3 π 〖(0.001)〗^3

bacterial inhibitors abolish the most bacteria. In the future‚ people will choose the most effective bacterial inhibitor; therefore‚ they save both money and time. If the disinfectants are applied to the bacteria‚ then the zone of inhibition will increase because disinfectants are antimicrobial agents that are applied to non-living objects‚ and a petri dish is a nonliving

Experiment 3: ANALYSIS OF UNKNOWN ACID SAMPLE USING TITRATION METHOD Date of Experiment: 4 September 2012 Introduction An acid-base titration is a procedure used in quantitative chemical analysis to determine the concentration of either an acid or a base. Titration is the slow addition of an acid (or a base) of known concentration from a burette (a narrow graduated cylinder) to a base (or an acid) of unknown concentration fin an Erlenmeyer

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time
