We were able to ignore the terms on the right side of the equation because we know mass is conserved within the reaction. Also the conservation of atoms tells us that the ratio of moles of copper chloride to aluminum is constant. So given the amount of copper chloride that reacted, we could find the amount of aluminum that reacted. If all the aluminum dissolved and the liquid was still blue, we would know that aluminum was the limiting reagent. We would also be able to calculate the mass of the original aluminum wire if we were able to measure the mass of the leftover copper. By finding the ma...

It plays a significant role in biology, chemistry, physics, and in nearly every single part of our life. Diffusion is a result of the continuous thermal motion of atoms and particles and therefore goes from a high concentration gradient to ... ...

Purpose The purpose of this lab was to measure the heat of solution through heating the two solutions Na2S2O3 and NaC2H3O2 that we used for solutes. Procedure Prepared the data table with five columns. Prepared a cold water-bath. A small plastic water-tub with ice was filled in. Fill a 600mL beaker three-fourths full of distilled water. Made a hole in the ice large enough for the beaker.Cut a square of corrugated cardboard slightly larger than the top of the plastic foam cup.Made a hole in the center of the cardboard piece with a cardboard throw a pencil. Make a second hole in the center. Inse...

Purpose The purpose of this experiment was twofold. The greater being, as implicated in the title, to become familiar with the scientific method. Meaning that with this experiment, greater knowledge about Laboratory tools, procedures as well as how to formulate and test a proper hypothesis will be learned. Also with this experiment, students will learn a great deal as to how Alka-Seltzer reacts in different mediums. Hypothesis After observing how Alka-Seltzer reacted in room temperature D.I. water, a variety of different hypothesis could be made as to how the Alka-Seltzer would react when the ...

There is good reason to believe that long-term changes in the chemistry of some sensitive soils may have already occurred as a result of acid rain. As the acid rain moves through the soil it can strip the soil of any vital nutrients ... ...
