Calculate the work done in lifting a 4-lb book to a height of 8ft. I think that the answers need to be in newtons, meters, and joules but I'm not sure how to convert them.
if smaller what does this tell you about concentration you determined. write equilibrium exoression to rationalize explanation. How would temp impact ksp
I am given the 10 ml of .200M Fe(NO3)3 and .25 ml of .00200 KSCN and 14.75 ml of .500 M of HNO3. How do I figure out the initial concentration of FE3+ and SCN-.
positronium consists of an electron and a positron same mass opposite charge orbiting round their common centre of
Why should a distilling flask be filled to not more than two-thirds of its capacity at the beginning of a distillation procedure?
We often hear the terms organic, natural, and chemical in the media. Organic and natural are usually used to imply that a product is "healthy" and/or "environmentally friendly" while chemical often implies negative implications for health and for ..

Calculate the overall relative standard deviation, the relative standard deviation of the method, and the relative standard deviation of the sampling process.
Sometimes there is no active hard constraint. Assume that the fired heater in Figure has no hard constraint, but that a side reaction forming undesired.
Calculate the enthalpy change in kilojoules when some KOH is added to 47.727 g of water and the temperature increases
The density of acetic acid vapor at the narmal boiling point, 118.5 degrees C, is given as 3.15 g/L (normal boiling point is the boiling point at P =1 atm). a) calculate the fraction of the vapor that is the monomer and the fraction that is the dim..
