Given that the density of solid sodium is 0.968 g/cm^3, estimate the atomic (metallic) radius of a Na atom. Assess the value obtained, indicating why the result is only an estimate and whether the actual radius should be larger or smaller than the..
Calculate kp given that the initial pressures of nitrogen are 95 atm and 80 atm, respectively, and the equilibrium pressure of nitrogen oxide is 6.0 atm. I know the answer is 5.1x10^-3. I am trying to find how is that number possible.
The flame produced by the burner of gas (propane)grill is a pale blue color when it mixes with propane(C3H8) to burn it completely. For every gram of propane that flows through the burner, what volume of air is needed to burn it completely?
Assume that 50.00ml of 0.100M HCl was added to 125ml of 0.100M sodium acetate. Is the resulting solution a buffer? Why or why not? Calculate the pH of the resulting solution.
