Question- Sketch a potential energy diagram for rotation about the C-C bond in propane (eclipsed and staggered conformations)
Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
The heat of fusion of thallium is 21 j/g, and its heat of vaporation is 795j/g. The melting anf boiling points are 304 degress celcius. The specific heat of liquid thallium is 0.13 j/g*c.
If 3.7 g of butanoic acid, C4H8O2, is dissolved in enough water to make 1.0 L of solution, what is the resulting pH
The decomposition of DDT is a first order process with a half-life of 56.0 days.
A calorimeter contains 125 g of water at 26.1°C. A block of metal with a mass of 25 g is heated to 96.5°C and then placed in the water in the calorimeter.
What is the molarity of the prepared naoh solution as determined in the titration? How many moles of OH are present when the end point is reached? What color should the solution appear at end point?
Calculate the molarity of the ions present in these salt solutions. Assume each salt to be 100% dissociated. Please show all work.
A 0.204 g sample of a CO3^2- antacid is dissolved with 25.0 mL of a 0.0981 M HCl. The hydrochloric acid that is not neutralized by the antacid is titrated to a bromophenol blue endpoint with 5.83mL of 0.104 M NaOH. a) Calculate the number of moles..
