  2. Learn about the fundamental concepts of chemistry including structure and states of matter, intermolecular forces, and reactions. You’ll do hands-on lab investigations and use chemical calculations to solve problems. Note: Save your lab notebooks and reports; colleges may ask to see them before granting you credit. Problem : Given that the free energy of formation of liquid water is -237 kJ / mol, calculate the potential for the formation of hydrogen and oxygen from water. To solve this problem we must first calculate ΔG for the reaction, which is -2 ( -237 kJ / mol) = 474 kJ / mol. Knowing that ΔG = -nFE o and n = 4, we calculate the potential is -1.23 V.

  6. Problem 4: If my oven has a volume of 1,100 L, a temperature of 250º C, and a pressure of 1.0 atm, how many moles of gas does it hold? P denotes pressure (in either atm or kPa), V denotes volume in liters, n is equal to the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas in Kelvin. Chemistry is the study of the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. Chemistry focuses on the interactions between different types of matter, particularly reactions that involve electrons. Percent Solutions. One way to describe the concentration of a solution is by the percent of a solute in the solvent. The percent can further be determined in one of two ways: (1) the ratio of the mass of the solute divided by the mass of the solution or (2) the ratio of the volume of the solute divided by the volume of the solution.
