95 grams of sodium acetate is dissolved in enough water to make 75 mL of solution. Calculate the pH of the resting solution
Decide whether or not each of the following metals dissolves in 1M HCl. For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
Calculate the pressure difference between CH4 and an ideal gas under these conditions. The van der Waals constants for CH 4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
A balloon has a volume of 10,500 liters, and the temperature is 15C. If the temperature were -25C, what would the volume of the balloon be.
Calculate the enthalpy and entropy departure for water at 400 C and 30 MPa using generalized correlations. Compare these values to those in the steam tables
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
what is happening when Nh4Cl is added to NH3 (a basic solution)? what is happening when HCl is added to NH3? how are these example
As2O3(s) + NO3-(aq) --> H3AsO4(aq) + N2O3(aq) (acidic solution) what is the oxidizing and reducing agent?
the equilibruium constant Kc for the reaction A(g)+ B(g)----> C9(g) is 0.76 at 150C. If 0.800 mol of A is aded to 0.600 mol of B in a 1.00-L container at 150degrees C
a sample of gas occupoes 17ml at -112 degrees C. what volume does the sample occupy at 70 degrees C.
Three bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 32.0 mL. The first bulb has a volume of 35.0 mL and contains 3.00 atm of argon, the second bulb has a volume of 250 mL and contains 2.27 atm of neon
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more complicated, but this is a reasonable first approximation.)
In this exercise it was assumed that the initial temperature of the metal was the same as that of the boing water. Qualatively, how would the calculated specific heat of the metal be affected
