Calculate the lattice energy for the hypothetical ionic compound M2X from the information given below.
In a synthesis experiment you obtain a sample of product on which you do a melting point determination and find a melting point range of 108.0 to 114.3 degrees Celsius. The sample is supposed to be benzoic acid.
when filled with water (d=1.00 g/cm 3) the flask and it contents weigh 518.3 g. what is the flask's volume?
Explain how the designed sensing strategy functions. Point form answers are acceptable, feel free to use a diagram in your explanation.
Calculate Qsp for calcium flouride (Ksp=3.9 x 10^-11) when 230.0 mL of a 0.00790 M solution of Ca(NO3)2 is added to 275.0 mL
if each reactant molecule in the above image represents 0.0157 mol and the reaction yields is 89%, how many grams of Si-containing product form?
A center of chirality (from the Greek cheir, hand) imparts the property of handedness to a molecule. In this part of the experiment, the left- or right- handedness of molecules with a chiral center will be illustrated with models.
What is the concentration of Cu2+ in the following cell at 25 degrees C if the cell voltage is 0.955V?
The temperature dependence of the vapor pressure is given by the equation: Ln p = Ln A - deltaH(vapor)/RT. Where p = pressure, T = temperature, A = pre-exponential constant, and delta h (vapor) is the enthalpy of vaporization. Solve for vapor pres..
Say, for example, that you had prepared a Buffer, in which you mixed 8.203 g of sodium acetate, NaC2H3O2, with 100 ml of 1.O M acetic acid. What would be the initial pH of Buffer C.
For a particular reaction, H = -30. kJ and S = -88 J/K. Assume that H and S do not vary with temperature
