First, the graph of the population versus time is about direct proportional. However, if we see the changes (difference between years), we can see the some differences. First, between 1801 and 1811, there is least population increase in the chart. Between 1811...
Introduction The purpose of experiment is to determine the order of reaction with respect to KMnO4. Mix KMnO4 and H2C2O4 then, stir it until color become colorless. It takes some times. Also, this experiment needs to measure the time until color become colorl...
Aim: /Experiment 1. Find out the ΔH of neutralization /Experiment 2. Find out the heat of combustion of the ethanol. /Experiment 3. Find out the heat of reaction between CuSO4 and Mg. Hypothesis: /Experiment 1. I think the result become negati...
*Aim According to Hess’s law, the heat of reaction of the one reaction should be equal to the sum of the heats of reaction for the other two. Measure the heat released by 3 reactions by using a Styrofoam-cup to than calculate for the heat of reaction, ΔH, fo...
1.Calculate the mean, standard deviation and percent standard deviation of your t-values. Include the values in a table. 2.Two of the liquids, 2-propanol and acetone, had significantly different t-values. Explain the difference in t values of these substan...
