Today in Chemistry me and my partner Cynthia traded our mixture with Sam,Joel, and Damian and preceded to separate there mixture of sand, iron, and calcium chloride. First measured the weight of the tray and beaker that we will use to contain the materials. We than preceded to measured the mixture all together and subtracted the weight of the beaker, the original beaker was 413.1g. After this we than separated the calcium chloride from the sand iron by using wire as a way of filtration. Then we set the calcium chloride in a tray aside and used a magnate to separate iron from the sand. We than measured on the scale the sand and iron.
Afterwards we used the filtration technique by putting filter paper in a cone and over a flask and dumped the calcium chloride. After pouring water on top of it the calcium chloride which resulted in it dissolving. Thus separating the little bit of solid from it. As the Calcium Chloride turned into a liquid. we then measure the liquid on a scale and subtracted the the weight of the flask. Thus giving us how much of the calcium chloride was used.
