Supposed that some magnesium oxide smoke escaped during the investigation. Would the MgO ration have increased, decreased or remained unchanged? explain your answer using sample calculations. How would the value you calculated for the percentage composition of magnesium oxide would have been affected if all the magnesium in the crucible had not reacted? Support your answer with sample calculations. • Why would your % composition be higher than the theoretical value? • Why would your % composition be lower than the theoretical value?

There are various methods for finding the composition of analloy (a metal-like mixture). Show that calculating the mass % of Mg in a magnesium-aluminum alloy (d=2.40 g/cm³) gives thesame answer (within rounding) using each of these methods: (a) a 0.263-g sample of alloy (d=of Mg 1.74 g/cm³; d=of Al 2.70 g/cm³); (b) an identical sample reacting with excess aque-ous HCl forms 1.38x10^-2mol of H₂; (c) an identical samplereacting with excess O₂ forms 0.483 g of oxide.
The hydrated salt, MY3·xH2O, was heated strongly in a crucible to remove all the water molecules of crystallization. The data for this experiment are given in the table below.Mass of empty crucible and cover 28.86 gMass of crucible, cover, and hydrated salt 32.86 gMass of crucible, cover, and anhydrous salt 31.24 gMolar mass of anhydrous salt 238.03 g/mol (i) Calculate the % composition by mass of water in the hydrated salt. (ii) Determine the value of x. (iii) M is in Period 4 of the Periodic Table of the Elements.If Y = NO3– , identify the element M.
Find the percentage composition by mass of each compound given: Raw Materials: 500 g calcium polysulphide and 1.5 kg hydrochloric acid Actual Yield: 343.4g precipitated sulfurWhereas the balanced chemical reaction, as given in the problem, is: CaS5+2HCl => 4S + CaCl2 + H2SI think for this solution, total mass should be calculated first. Please include the detailed solution whereas the units or label is present. Thank you so much for helping me out. I am sad.
Ten replicate analyses of the concentration of mercury in a sample of commercial gas condensate gave the following results:23.3 22.5 21.9 21.5 19.9 21.3 21.7 23.8 22.6 24.7 ng ml−1
A 1.00 g sample of a magnesium-aluminum alloy yields 0.107 g H2 when treated with an excess of HCl(aq). What is the percentage by mass of Al in the alloy? [Hint: This is the inverse of Example 4-16. To solve this problem, let m and 1.00 - m be the masses of Al and Mg, respectively, and then use these masses in the setup above to develop an equation that relates m to the total mass of H2 obtained. Then solve for m.]
Explain the significance of gravimetric analysis? Give a specific example by enumerating the steps of the analysis.
A 0.6447 g portion of manganese dioxide was added to an acidic solution in which 1.1402 g of a chloride containing sample was dissolved. Evolution of chlorine took place as a consequence of the following reaction: MnO2(s) + 2Cl- + 4H+ ® Mn2+ + Cl2(g) + 2H2O After the reaction was complete, the excess MnO2 was collected by filtration, washed, and weighed, and 0.3521 g was recovered. Express the results of this analysis in terms of percent aluminum chloride. (Al:27.0 ; Mn:55.0 ; O:16.0 ; Cl:35.5 ; H:1.0 g/mol)

Food products is ash for elemental analysis. Calculate the ash content of the sample if the residue in the beaker is 214.5 mg if the weight of sample, crucible, and crucible with residue is 3.2154 g, 15.2841 g, and 15.4986 g respectively.
How will the relative number of moles of Mg and O be affected if the following procedural errors are made? Briefly explain 1. The crucible is not brought to constant mass before the Mg is added 2. Water is not added after the first heating of Mg, and the entire solid in the crucible is considered to be magnesium oxide 3. Some of the fluffy white precipitate is lost before the crucible is weighed for the last time. 4. In an effort to begin a second sample while the first is cooling, the hot crucible containing the solid from determination 1 is accidently dropped, and a small chip is lost from the crucible.
A student carrying out an experiment was in a hurry to finish. He decided to omit the centrifugal step, although the solution was cloudy. Should this cause a higher or lower result in the determination of the percent of copper in a brass sample? Higher percent or lower percent? Explain.
