Materials engineers often create new alloys in an effort to improve the properties of an existing material. ZnO-based semiconductors show promise in applications like light-emitting diodes, but their performance can be enhanced by the addition of small amounts of cadmium. One material that has been studied can be represented by the formula Zn 0.838 Cd 0.162 O. (These materials are solid solutions, and so they can have variable compositions. The non-integer coefficients do not imply fractional atoms.) Express the composition of this alloy in terms of mol % and wt %. mol % = % Zn wt% = % Zn

How many grams of iron(II) oxalate dihydrate, Fe(C2O4)·2H2O, mass can be produced when a student begins the synthesis with 3.305 g of ammonium iron(II) disulfate hexahydrate, (NH4)2Fe(SO4)2·6H2O? Report your answer in grams to three (3) decimal places.
In the production of printed circuit boards for the electronics industry, a 0.765 mm layer of copper is laminated onto an insulating plastic board. Next a circuit pattern made of a chemically resistant polymer is printed on the board. The unwanted copper is removed by chemical etching and the protective polymer is finally removed by solvents. One etching reaction isCu(NH3)4Cl2(aq) + 4NH3(aq) + Cu(s) → 2Cu(NH3)4Cl(aq)A plant needs to manufacture 8700 printed circuit boards, each 7.55cm x 18.0cm in area. An average of 72.0% of the copper is removed from each board (density of copper=8.96g/cm3.) What mass of Cu(NH3)4Cl2 reagent is required?

The human bones make up about 18% of the total body weight, and 70% by weight of human bone is hydroxyapatite. Calculate the number of moles of hydroxyapatite in an average adult.
The "barking dog" reaction is an exciting combustion reaction that generates a bright blue flame because sulfur is produced during the reaction (sulfur burns blue!). At the end of the reaction, a "woosh" sound is made which sounds like a dogs bark (hence the name of the reaction). Assume the reaction is carried out in a closed container. CS₂2 +4N₂O CO₂ + SO₂ + S + 4N₂ Note: the equation is balanced How many moles of CO₂ can you generate if you were to carry out the reaction with 8.28 g CS₂?
Chlorophyll molecules are responsible for the green pigmentation of plants. Differing chemically isolated molecular chlorophyll compounds are named as "Chlorophyll X" (where "X" is a variable denoting the actual molecular fragments which are represented by the labels R2, R3, R7, Rg, R17). Suppose one molecule of ChlorophyllX contains 5 oxygen atoms, and Chlorophyll X is 13.14 % oxygen by weight. Using only this information and the atomic mass of oxygen, determine the molecular mass of Chlorophyll X. The Chlorophyll X molecule contains one magnesium atom. What mass of magnesium is found in 7.11 g of Chlorophyll X compound?
To help farmers and gardeners , commercial fertilizers have a big three -number "NPK" label on the bag that gives the amounts of three key plant nutrients: nitrogen , phosphorus and potassium. For example , a bag of "-10-10-10" fertilizer has 10% by mass nitrogen , 10% by mass potassium as potash (K2O), and 10% by mass phosphorus as phosphate (P2O5). Suppose a certain fertilizer has the following composition. What should the first (nitrogen) number on the bag label be? That is, calculate the the percent by mass of nitrogen in this fertilizer. Round your answer to the nearest percent.
The class of ternary compounds called carboranes (containing the elements carbon, boron and hydrogen) have played a prominent role in many areas of fundamental chemical research. In particular, they have provided many interesting examples for testing theories on chemical bonding and structure. A particular carborane has the following mass percentages: 21.30%C and 67.09%B. What is the empirical formula of this compound? Choose appropriate coefficients in the formula below. C B H
A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?
