Lab experiment 12 Percent of water in a hydrate The goal of Experiment 12 was to learn how to calculate the percent of water (by mass) in barium chloride and an unknown hydrate salt‚ as well as properly calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and

a gravimetric factor of 1:1‚ sample 1 resulted in the formation of 0.5874g BaSO4 from 0.4004g of SO42-‚ while sample 2 resulted in the formation of 0.4073g BaSO4 from 0.3985g of SO42-. The two samples‚ respectively‚ produced a percentage of 50.32% and 35.06% SO3-; averaging a net percentage of 42.69% with a standard deviation of ± 10.79%. Purpose The purpose of this experiment is to determine the mass of sulfate in the precipitate from the reaction of BaCl2 (aq) +

crystallized from water solutions appear to be perfectly dry‚ yet when heated they discharge large quantities of water. An example can be hydrated copper (II) sulfate. Exactly this salt is used in the described experiment. RESEARCH QUESTIONWhat is the number of moles of water of crystallization associated with one mole of copper (II) sulfate‚ in the hydrate CuSO4 * xH2O (s)? The independent variable in this experiment is sample thermal treatment ( heating and cooling) and the dependent variable is the number

Methane hydrate is a crystalline solid which consists of methane molecules inside the crystal structure. The methane molecules are trapped inside the cage-like structure of solid water‚ ice. Methane hydrate looks like ice‚ but it would burn and release energy when it is close to a flame. That is why it also called fiery ice. There are three types of crystal structures of methane hydrate which are determined by the number of water molecules inside the crystal. There are structure with 46‚136 and

For an acute episode‚ the best medication to treat with is analgesia. Morphine sulfate is given to relieve pain and reduce ureteral spasm (LeMone‚ 2015‚ P.758). o Other assessment data I would expect to find is complaints of flank‚ back‚ or abdominal pain.

4. Aspects of Formation for Laity Both the Fathers of Vatican II and the bishops at the 1987 Synod on Laity use the word “integral” to describe the formation for laity. The lay apostolate can only be effective “through manifold and integral formation”. In discovering and living their proper vocation and mission‚ the laity must be formed according to the union which exists from their being members of the Church and citizens of human society. The many interrelated aspects of a totally integrated
