One way to analyze for the amount of phosphorus in a rock is to precipitate the phosphorus as MGNH4PO4, which is then heated to tum it into Mg2P207. What mass of Mg2P207 will be obtained from a 2.102 g sample of a rock that contains 86.52% Ca3(PO4)2 (and no other source of phosphorus) if this analysis is done? Hint: you will not be able to write an equation for this problem. Please do not include units in your answer.

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 3232 slices of bread and 4545 slices of cheese.

15. Kkura found a sulfide ore in the dungeon which she identified to be chalcocite. While waiting for her debut, she read from a journal that grinding and "roasting" (heated strongly with oxygen gas) chalcocite can generate copper (1) oxide, a pigment used to color ceramics. Find the amount of copper(I) oxide she can produce from 53 grams copper(I) sulfide. Cu2S(s) + O2(g) –> Cu2O(s) + SO2(g)

91. A common demonstration in chemistry courses involves adding a tiny speck of manganese(IV) oxide to a concentrated hydro- gen peroxide (H₂O₂) solution. Hydrogen peroxide decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). Manganese(IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. Write the balanced equation for the decomposition reaction of hydrogen peroxide. 92. Iron oxide ores, commonly a mixture of FeO and Fe,O,, are given the general formula Fe,O,. They yield elemental iron when heated to a very high temperature with either carbon monoxide or elemen- tal hydrogen.
