Determine the limiting reagent and calculate the theoretical
mass of aluminum sulfate formed and the volume of hydrogen gas at
23oC and 752 mm Hg formed if 10.00g of aluminum is
reacted with 10.00g of sulfuric acid. Be sure to show proper
formulas, balanced chemical equations, solution maps and a clear
and complete set-up as instructed including proper dimensional
analysis as appropriate for the problem.
aluminum nitrate reacts with calcium sulfate to produce aluminum
sulfate and calcium nitrate. If 4.4 grams of aluminum nitrate and
1.9 grams of calcium sulfate are mixed and allowed to react to
completion, how many grams of calcium nitrate could be
produced?

Discuss sulfur and its pathways in soil (i) plant
uptake, (ii) sulfur mineralization, (iii) sulfate adsorption in
acidic soils on iron oxides, (iv) the adsorption of sulfate on
carbonates in alkaline soils, (v) the role of plant residues, (vi)
reduction of sulfate to sulfide.
The aluminum in a 1.258-g sample of impure ammonium aluminum
sulfate was precipitated with aqueous ammonia as the hydrous Al2O3
. XH2O The precipitate was filtered and ignited at 1000°C to give
anhydrous Al2O3, which weighed 0.1060 g. Express the result of this
analysis in terms of:
% NH4 Al(SO4)2 = %
% Al2O3= %
% Al = %
Sulfur trioxide, ammonia gas, and water will react to form
ammonium sulfate. Determine the % yield when 3.78g of ammonium
sulfate forms from the reaction of 2.51g of sulfur trioxide, 1.55g
of ammonia, and 0.804g of water.
The sulfur in an 8-tablet of sample of the hypnotic drug
captodiamine,c21h29ns2(359.6g/mol) was converted to sulfate and
determined gravimetrically.calculate the average mass of
captodiamine per tablet if 0.3343g baso4 was
recovered.
How many valence electrons does sulfur atom in a sulfate ion
have?
The answer is 12 valence electrons. I am unsure how the question
was calculated.
Why is the answer not 8 valence electrons?
Calculate the cost of a single aluminum atom in a roll of
aluminum foil, correct to 3 significant digits.
- The cost of a roll is $2.39
- The area of the roll is 9.28 square meters
