Researchers are attempting to create a new battery based on the following chemistry and would like the battery to produce 1.0-1.2 volts. Given the standard cell potential of the reaction, they propose to connect 3 identical cells inside the single new battery. Calculate the voltage of this (3-cell) battery at 25 C when 1.3 M Fe and 0.010 M Fe in pH 3.1 buffer react with O at 0.20 atm. (For full credit your answer must be correct to /-0.02.)

Why is the structure of molecule important to its function?

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
