4.48 Elemental phosphorous is used in the semiconductor industry. It can be obtained from an ore called fluoroapatite via reaction with SiO2 and C: 4Ca5( PO4)3F+18SiO2+30C3P4+30CO+18CaSiO3+2CaF2 Suppose a particular semiconductor production plant requires 1500 kg of P4. If the recovery of P4 from this reaction is 73% efficient, what mass of fluoroapatite is needed?
If Cu(NO3)2 + 2 H2O à Cu(OH)2(s) + 2 HNO3(aq) would any copper ions be produced? Write the net ionic equation for this reaction.
Consider the series of reactions to synthesize the alum (KAl(SO4 )2 · xH2O(s)) from the introduction. (a) Assuming an excess of the other reagents, from one mole of aluminum Al (s), how many moles of alum will be produced? (b) Assuming an excess of the other reagents, from one mole of potassium hydroxide KOH, how many moles of alum will be produced? (c) Assuming an excess of the other reagents, from one mole of sulfuric acid H2SO4 , how many moles of alum will be produced? (d) If you start the synthesis with 1.00 g of Al, 40.0 mL of 1.50 M KOH, and 20.0 mL of 9.00 M H2SO4 , which of the three will be the limiting reagent? (e) Assuming that the product is anhydrous (that there are no waters of hydration), calculate the theoretical yield of alum, in grams, based on the amounts of reagents in part (d). 3. Consider the nickel salt: (NH4 )2Ni(SO4 )2 ·y H2O (Ammonium Nickel Sulfate Hydrate), where y is the number of coordinated waters. (a) Assuming that the product is anhydrous (y = 0),…
The price of (a) CoCl2•6H2O is $25.00 per 100 g and (b) NH,CI was $11.35 per 500 g. Calculate the costs of each of these reagents used in this preparation. If cost were a determining factor which of these would be used as a limiting reagent? (a)
Because the oxide ion is basic, metal oxides react readily with acids.(a) Write the net ionic equation for the following reaction:FeO1s2 + 2 HClO41aq2¡Fe1ClO4221aq2 + H2O1l2(b) Based on the equation in part (a), write the net ionicequation for the reaction that occurs between NiO(s) and anaqueous solution of nitric acid.
b. (i) (ii) A green solid has the empirical formula FeBr3·5NH3 H₂O. Upon reaction with an excess of aqueous AgNO3 it is found that 1 mole of the solid precipitates 3 moles of AgBr. Heating the green solid leads to loss of 1 mole of H₂O to yield a blue solid with the same ratio of Fe:Br:NH3 as found in the green solid. The reaction of 1 mole of the blue solid with excess of aqueous AgNO3 produces 2 moles of AgBr. Draw and name the octahedral green and blue complexes. An octahedral complex having the formula [M(dien)(NH3)(OH₂)F] has a total of 15 isomers. In the sum formula "dien" represents the tridentate diethylenetriamine ligand, which can adopt meridional or facial coordination modes. Draw structures of 8 possible isomers, clearly showing any pairs of enantiomers. The tridentante ligand may be abbreviated as below for simplicity. H₂N : = ΝΗ NH :NH2 N diethylenetriamine (dien) N N
Would you expect potassium perchlorate, KClO4(aq), in a concentrated acidic solution to act as an oxidizing agent or as a reducing agent?
Titanium (IV) exists in aqueous solution but not as the Ti4+(aq) ion. Suggest the identity of the species.

(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent. In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant. 2. In a redox reaction, the reducing agent is oxidized and it gains electrons. In a redox reaction, the oxidizing agent is reduced and it gains electrons. 3. Bending stress is also known as flexural stress. The test used in observing the mechanical strength of chocolate is the three-point bend test. 4. The flexural strength of materials may be expressed in Pascals. Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.
