Carbohydrates, a class of compounds containing the elements carbon, hydrogen, and oxygen, were originally thought to contain one water molecule(H2O) for each carbon atom present. The carbohydrate glucose contains six carbon atoms. Write a general formula showing the relative numbers of each type of atom present in glucose.
Open the Build a Molecule simulation (http://openstaxcollege.org/l/16molbuilding) and select the Larger Molecules tab. Select an appropriate atoms Kit to build a molecule with two carbon and six hydrogen atoms. Drag atoms into the space above the Kit to make a molecule. A name will appear when you have made an actual molecule that exists (even if it is not the one you want). You can use the scissors tool to separate atoms if you would like to change the connections. Click on 3D to see the molecule, and look at both the space-filling and ball-and-stick possibilities. Draw the structural formula of this molecule and state its name. Can you arrange these atoms in any way to make a different compound? 35. Use the Build a Molecule simulation (http://openstaxcollege.org/l/16molbuilding) to repeat Exercise 2.34, but build a molecule with two carbons, six hydrogens, and one oxygen. Draw the structural formula of this molecule and state its name. Can you arrange these atoms to make a different molecule? If so, draw its structural formula and state its name. How are the molecules drawn in (a) and (b) the same? How do they differ? What are they called (the type of relationship between these molecules, not their names).

Solve word problems involving calculations that apply the Law of Definite Composition and Law of Multiple Proportions. 1.) There is a total of 100g of Aluminum oxide (Al2O3) in a beaker. How much Aluminum in grams is in the 100g of Aluminum oxide? 2.) The mass of oxygen that combines with 1g of nitrogen to form 2 different compounds are 2.28g and 0.570g, respectively.

Solve word problems involving calculations that apply the Law of Definite Composition and Law of Multiple Proportions. )There is a total of 100g of Aluminum oxide (Al2O3) in a beaker. How much Aluminum in grams is in the 100g of Aluminum oxide? There is 100g each of 2 different compounds containing Sulfur and Oxygen. The first compound contains 50g of Sulfur and the second compound contains 40g of Sulfur. Show how these data illustrate the Law of Multiple proportions by calculating the simplest whole number ratio. Please show your solution clearly.
1. Demonstrate the Law of Multiple Proportions with the following data: a. Iron forms two compounds with chlorine, compound X and compound Y. When 3.00 g of compound X was analyzed, it was found that 1.68 g of Cl combined with 1.32 g of Fe. When 5.00 g of compound Y was analyzed, it was found that 3.28 g of Cl combined with 1.72 g of Fe. To illustrate the Law, one needs to know how much of one element combines with the same mass as the other element in each compound, but the data above give different masses for both Fe and Cl. One way to standardize the data is to find out how much of one element, say C1, combines with exactly 1 g of the other, say Fe. This can be done by a simple proportion method ("if 1.75 g of Cl combines with 1.25 g of Fe, how many g of Cl would combine with 1.00 g of Fe...") Do this for both compounds, X and Y.
