I have neither obtained nor given aid on this assignment outside of data discussions with my lab team. “ Signed_________________________________________ Abstract A common road salt‚ magnesium chloride‚ was analyzed in the lab to test its effectiveness as a road salt. The Van’t Hoff factor of the salt and the enthalpy of dissolution when dissolved in pure water were experimentally tested to evaluate its many characteristics as a

valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction (that is‚ how many moles of A react with a given number of moles

Find the mass of a clean crucible and lid. USE THE SAME BALANCE DURING THE ENTIRE EXPERIMENT. 2. Curl the magnesium ribbon around a pencil to make a size that just fits inside the crucible. Do not curl the ribbon too tightly. 3. Describe the magnesium ribbon. 4. Find

The Law of Definite Proportions states that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. This relates to the magnesium oxide lab because we tested out this theory to see if it is true that the law of definite proportions says that a chemical compound contains the same element in exactly the same proportions by mass regardless of the size of the sample or source of the compound. In this experiment

Whilst reacting with the hydrochloric acid‚ it dissolved and bubbles were visible. The hydrochloric acid slowly diffused downwards. Calculations: Volume of un-diffused hydrochloric acid = 25 cm³ Average mass of magnesium = 0.038

In terms of advancing up the corporate ladder‚ your primary ethical principle can be seen in many ways. The utilitarianism approach would be my primary approach because it suits the overall goal of not only the company you work for‚ but any company in general. Having everyone on board for the main focus and understanding should picture the ethical standards that the company demands for their employees‚ and themselves. Abiding by these ethical standards‚ not only helps the company move forward‚ but

1. What do you think the diagnosis is for this patient and why? o I think the diagnosis is a urinary tract infection because the patient has urinary frequency and nocturia‚ with a low fever. Sometimes when patients have a fever‚ it can increase their pulse and respirations (LeMone‚ 2015‚ P.751). 2.
