Plutonium 239 follows a first order reaction. It takes 1.89 x 10^6 years for one mole Pu 239 to decay to one atom. Find half life.
Calculate the initial effusion rate. If this rate continued how much time would pass until the pressure dropped to 0.90 bar? (actually the rate changes with pressure- indicated why using the equations). assume values for nitrogen
a solution of water kb0.512 c and glucose freezes at 4.15. what is the molal concentration of glucose in this solution?
What is the equilibrium concentration of H+ in the following reaction, assuming that you start with a 1.00 M solution of acetic acid (CH3COOH).
HFC's (hydrofluorocarbons) are replacing CFC's (chlorofluorocarbons) because the C-H and C-F bonds are stronger than C-Cl bonds. If the bond enthalpy of a C-F bond is 482 kJ/mol.
Calculate the specific heat (J/g?C) for a 50.2-g sample of a metal that absorbs 355J when temperature increases from 35.0 ?C to 57.9 ?C
Which of these is a coefficient in this chemical reaction? P4s(s)+5o2(G) p4o10(S)
