Lab 2 Sara Rodriguez Period 2 Purpose: What is the more accurate way to measure volume‚ by using displacement or by using a ruler? Hypothesis: If the method of displacement is used ‚ then the results will be more accurate than measuring the volume using a ruler. Materials: -250 mL graduated cylinder -Triple beam balance -A weigh boat -Ruler -Samples Procedure: 1. Gather materials such as ‚ samples‚ weigh boat‚ triple beam balance ‚ graduated cylinder‚ ruler and water. 2. Take the materials

Problem What effect does the different concentration of hydrochloric acid have to the rate of diffusion of agar that is dissolved with sodium carbonate and phenolphthalein? Introduction Diffusion is a process where the molecules intermingle as a result of their kinetic energy of random motion and is the net movement of like molecules down their concentration gradient‚ which is the energy inherent in their constant molecular motion makes them collide and careen outward from the region of higher
