In applying the kinetic molecular theory to gases, we have assumed that the walls of the container are elastic for molecular collisions. Actually, whether these collisions are elastic or inelastic makes no difference as long as the walls are at the same temperature as the gas. Explain.
The density of water = 1.000 g/mL. The liquid's final volume is not changed by adding the solid. The calorimeter loses only a negligible quantity of heat.
Chlorous acid, HClO2, has a dissociation constant of Ka = 1.20 * 10^(-2). Assume that you have a 0.0755 m solution of this acid and calculate the concentration of H+ cations in the solution and degree of dissociation for a solution of the acid
What is the internal energy of an ensemble of 1 mole of particles having two non-degenerate electronic energy levels separated by 1000cm^-1 at 1310K?
She drinks a lot of water and has consume milk of magnesia(ph value 10.5) before she feels comfortable again. State the pH values of water and blood and whether its acidic or alkaline.
Calculate the pH of the solution at the half equivalence point. Explain how the pH at the half equivalence point is related to Ka for the weak acid.
Imidazole is a weak acid, and thus reacts with strong bases to form the corresponding anion. Show this reaction, and draw resonance structures that account for the stability of conjugate base.
Assuming that the atoms are spheres in contact along the face diagonal, what is the radius of a Ar atom (in Angstroms)? An angstrom = 10-10 m or 10-8 cm.
Compute the average decomposition rate of the organic acid - Average decomposition rate of the organic acid
The presence of a carboxyl band near 1640 cm-1 and two bands near 3000 cm-1 is good evidence of an alcohol B) The presence of a sharp, medium intensity band near 2720 cm-1 and a strong carbonyl band near 1700 cm-1 is good evidence of an alcohol
