A plant manufacturing nails and screws uses a large pool (volume = 10,000 L) to collect and treat its residual waste water before discharging it in a nearby stream. The manufacturing process makes use of a strong acid (HCl) and a weaker one (phosphoric acid, H3PO4; pKa1 = 2.148, pKa2 = 7.20, pKa3 = 12.15), […]
The energy change, DHdissolution, that occurs while dissolving an ionic compound in water can be exothermic or endothermic. Qualitatively illustrate the expected relationship between mass of compound and temperature change of solution in a Styrofoam cup calorimeter filled with water. Use different lines (solid, dashed) to represent the different DHdissolution (exothermic or endothermic)

A person weighing 150 pounds who is running 1 mile in ten minutes, will “burn” 100-120 Calories. A 200 lb person uses 135-155 Cal for the same run. A)How much ATP (in grams) is needed for such a workout? The molecular weight for ATP is 507 g/mol. The standard free energy for […]
I need the nomenclature/naming for the simple cycloalkane Bromide branch. I think the answer is similar, but I’m getting people with different answers: some write below but I’ve been told that is wrong as the Cyclo is probably 1, not 6 and the direction of counting may be different depending not the Carbons in the […]
Energy is classified as potential or kinetic. Potential energy is energy that is stored in an object, a rubber band for example. You stretch the rubber band and release it flying through the air. Once the rubber band is in motion it exhibits kinetic energy. A parked car, a child playing with a yo-yo and […]

Sometimes checking from the Winter Conferences wish list is easier in theory Roundup: Panthers extend Canadiens’ skidJacob Markstrom made 40 saves and Scottie Upshall scored 5:02 into the third period to help the Florida Panthers extend Montreal’s losing streak to six with a 2-1 win over the Canadiens on Monday night Mississippi StateMississippi State mixed […]
Given the following equation: 6H2O + 6CO2 –> C6H12O6 + 6O2 âH=+2803kJ/mol Find the amount of heat required (kJ) to produce 92.6 g…
“Pursue excellence, and success will follow, pants down.” I can just remember this line while I was watching the documentary on Fermat’s Last Theorem. This was said by Rancho on the movie 3 idiots which was a story about pursuing one passion to live a happy and fulfilled. This docoumentary was very inspiring […]
