In each pair of compounds, pick the one with the higher vapor pressure at a given temperature. Explain your reasoning. b. CH3CH2CH2OH or CH3OH
In each pair of compounds, pick the one with the higher vapor pressure at a given temperature. Explain your reasoning. c. CH3OH or H2CO
Determine whether each pair of compounds forms a homogeneous solution when combined. For those that form homogeneous solutions, indicate the type of forces that are involved. a. CCl4 and H2O
Which compound would you expect to have greater surface tension: acetone [(CH3)2CO] or water (H2O)? Explain.
Explain why the viscosity of multigrade motor oils is less temperature-dependent than that of single-grade motor oils.
When a thin glass tube is put into water, the water rises 1.4 cm. When the same tube is put into hexane, the hexane rises only 0.4 cm. Explain.
