Write the sum of the coefficients of the balanced chemical equation for the complete combustion of nonane. Enter only a number for your answer and remember if the coefficient is implied to be 1, then you have to include that in your sum.

The yield of a chemical reaction is defined as the ratio (expressed as a percentage) of usable output to the amount of raw material input. Suppose the yield of a chemical reaction depends on the length of time the process is run and the temperature at which the process is run. The yield can be expressed as follows: Yield 5 90.79 2 1.095x1 2 1.045x2 2 2.7812 1 2 2.524x2 2 2 0.775x1x2Here x1 5 (Temperature 2 125)y10 and x2 5 (Time 2 300)y30, where temperature is measured in degrees Fahrenheit, and time is measured in seconds. Use a data table to find the temperature and time settings that maximize the yield of this process.

Balance Equation: 2Al + 3CuCl2 * 2H2O -> 2Cu + 2AlCl3 + 6H20 1. Reproduce the following table in your document. Write the chemical reaction again in the indicated spot, typing the reactants under the word “reactants” and products under the word “products”. Then in the row labeled “Element”, list each element in the reactants and products. Assign oxidation numbers to each element in the reactants and products and write the oxidation number underneath each element in the table below. Explain how these were derived. (see table) 2. From the reactants, identify the oxidizing agent and reducing agent and input this into the table above. Explain, in a few sentences, how you determined the difference between the two. 3. Type out the complete ionic equation and the net ionic equation for the reaction. Explain how you arrived at your answer in a narrative (3-5 sentences), including why you canceled any ions as spectators.

diagram b is correct,     What procedures can be used to solve this problem? write down the plan for this new way to solve the problem.  1. first execute plan 1 to solve this problem. explain in every step. 2. solve the problem again - this time use the plan that you propose, plan 2. 3. finally, think about the way that you can use it to make sure that your answer makes sense. write your assessment.
