What stabilizes a colloidal suspension? Explain why adding heat or adding an electrolyte can cause the suspended particles to settle out.
Answer to relevant QuestionsThe solubility of benzoic acid, A solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of this solid is dissolved in 50.0 g of water, the freezing point is lowered by 5.40oC. What is the composition of the solid (by mass)? Assume ideal behavior. Slaked lime [Ca(OH)2] is used to soften hard water by removing calcium ions from hard water through the reaction Ca(OH)2(aq) + Ca2+(aq) + 2HCO3-(aq) → 2CaCO3(s) + 2H2O(l) In addition to CO2, two additional stable oxides of car-bon form. The space filling models for CO2 and the other two stable oxides are: What are the formulas for the two additional stable oxides of carbon? Explain the ...Using data from Appendix 4, calculate ΔHo, ΔSo, and ΔGo for the reaction Ns(g) + O2(g) → 2NO(g) Why does the NO formed in an automobile engine not readily decompose back to N2 and O2 in the atmosphere?
