Plot the following data, and from the graph determine ΔHvap for magnesium and lithium. In which metal is the bonding stronger?
Relevant QuestionsFrom the following data for liquid nitric acid, determine its heat of vaporization and normal boiling point. A 0.250-g chunk of sodium metal is cautiously dropped into a mixture of 50.0 g of water and 50.0 g of ice, both at 0oC. The reaction is 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) ΔH = –368 kJ Will the ice melt? Assuming the ...The critical point of NH3 is 132oC and 111 atm, and the critical point of N2 is –147oC and 34 atm. Which of these substances cannot be liquefied at room temperature no matter how much pressure is applied? Explain. Rationalize the difference in boiling points for each of the following pairs of substances: a. n-pentane CH3CH2CH2CH2CH3 36.2oC b. HF 20oC HCl –85oC c. HCl –85oC LiCl 1360oC d. n-pentane CH3CH2CH2CH2CH3 36.2oC n-hexane ...Argon has a cubic closest packed structure as a solid.
