What is the hybridization of phosphorus in the phosphonium ion (PH4+). If someone can tell me how to figure this out I would really appreciate it. Any shortcuts or hints on how to solve it
Which of the following equations represents the proper net ionic equation for the complete neutralization reaction between the weak acid HClO2 (aq) and the strong base KOH (aq)?
what is the order of increasing steric hindrance within these reactions and what is the reason for that order in terms of calculated energies, distance, and structures.
Calculate the standard cell potential and equilibrium constant at 25 C for the cell reaction in a direct methanol fuel cell. 2CH3OH (l) + 3O2 (g) --> 2CO2 (g) + 4H2O (l)
The variation of the atmospheric pressure p with altitude h is predicted by the barometric formula to be p = p0 e^(-h/H) where p0 is the pressure at sea level and H=RT/Mg with M the average molar mass of air and T the average temperature. Obtain t..
Consider an electron moving from left to right (toward positive x) in a constant potential of V = 2.0 eV with total energy, E = 5.0 eV. Let the electron be described as a free particle such that the constant potential DOES NOT depend on the spatia..
A different sample of carbon dioxide also contains 27% carbon and 73% oxygen. The percentages are the same for all samples analyzed. Explain these observations with respect to atomic theory.
determine the mass of snow that can be completely melted.use the table below to work the following
Find the equilibrium concentrations of A and B for a = 2 and b = 2. Assume that the initial concentration of A is 1.0 M and that no B is present at the beginning of the reaction.
calculate the amount of solute (g or mL needed to prepare the following solutions: a) 150 g of a 40.0%(m/m)LiBr solution. b) 450 g of a 2%(m/m) KCl solution. c) 225 mL of a 15%(v/v) isopropyl alcohol solution
A sample of sulfur weighing 0.210g was dissolved in 17.8g carbon disulfide. (Kb= 2.340C/m ) If the boiling point elevation was 0.1070C, what is the formula of a sulfur molecule in this environment
If 50.0 of ethanol (density 0.789g/mL) initially at 6.0 is mixed with 50.0 of water initially at 28.2 in an insulated beaker, and assuming that no heat is lost, what is the final temperature of the mixture?
the reaction must progress forward to attain equilibrium. The richer a reaction mixture is in product the higher its Q value is. The value of K does not change as a reaction progresses toward equilibrium.
