the minimum energy required to cause the photo electric effect in potassium metal is 3.69*10^-19 J. will photoelectrons be produced when light shines on the surface of potassium?if 400 nm radiation is shone on potassium,what is the velocity of the..
calculating theoretical yield for this experiment. It is a dehydration synthesis where one mol of hydrated salt yields 3 mol hydrates and 1 mol of anhydrous salt.
If you fill the larger tank with oxygen to a pressure of 105 atm, to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
For a given sample of {rm CH_3OH}, the enthalpy change on reaction is 19.0 kJ. How many grams of hydrogen gas are produced?
Calculate the partial pressure (in atmospheres) of each gas, Assuming that the total pressure of the gases is 1.34atm{rm atm} and that their mole ratio is 94 : 4.0 : 1.5 : 0.50,
Consider uJT=(dT/dP)H. (this means the rate of change of Temperature divided by the rate of change of pressure at constant enthalpy)
Consider a solution formed by mixing 30.0 mL of 0.100 M H2SO4, 24.5 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution.
