Suppose you measure out 2.45 g of a metal, which corresponds to 0.0908 mol of the metal, and react with enough hydrochloric acid to produce 12.11 g of the metal chloride. Based on the data, what is the formula for the chloride you produced? Select one: MCl2 MCl MCl3 M2Cl3
An unknown powder has been found at a crime scene. It is your job to identify the chemical formula for the substance and its common or generic name by searching the internet. Preliminary tests reveal that the possible elements that can be in the material are carbon, hydrogen, oxygen and nitrogen. Complete combustion of a 0.695 g sample of the unknown powder with excess O2 produced 1.2387 g of CO2, 0.5072 g of H2O, and 0 g N2. The molar mass of the substance was found to be about 222 g/mol.
The mineral iron pyrite (FeS2), typically, has a mass percentage of what is known as fool’s gold of 90-95%. The actual percentage in a sample can be determined using gravimetric analysis. To find the % mass of FeS2 the sulphur in FeS2 is firstly converted to sulphate (SO42-). These sulphate ions (SO42-) is mixed with an excess of barium chloride (BaCl2) to form barium sulphate (BaSO4), according to the following reaction: Ba2+(aq) + SO42- (aq) à BaSO4 (s) When the reaction has gone to completion, the BaSO4 precipitate is collected in a filter paper and carefully washed. The filter paper and its contents are then transferred to a crucible. The crucible and its contents are heated until constant mass is achieved. The data for the analysis of a mineral sample is shown in the table below: Initial Mass of mineral sample 17.5 g Mass of crucible and filter paper 144.60 g Mass of crucible, filter paper and dry BaSO4 196.89 g Molar mass…
A 0.4455 g sample of a pure soluble chloride compound is dissolved in water, and all of the chloride ion is precipitated as AgCI by the addition of an excess of silver nitrate. The mass of the resulting AgCl is found to be 0.9496 g. What is the mass percentage of chlorine in the original compound? %
