A waste treatment pond is 50m long and 15m wide, and has an average depth of 2m. The density of the waste is 85.3 Ibm/ft3. Calculate the weight of the pond contents in Ibf using a single dimensional equation for your calculation
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted.
Determine the molar mass of the nonelectrolyte if the osmotic pressure of the solution = 23.6 atm, also express your answerin g/mol?
what is the chemical equation that describes both these reactions? Please give the chemical equations of what happens in this situation
It takes 54.0 J to raise the temperature of an 8.00 g piece of unknown metal from 13.0rm ^circ C to 24.5^circ{C}. What is the specific heat for the metal?
Consider the equation A(aq) + 2B(aq) 3C(aq) + 2D(aq). In one experiment, 45.0 mL of 0.050 M A is mixed with 25.0 mL 0.100 M B. At equilibrium the concentration of C is 0.0410 M. Calculate K.
