Draw a molecular-level picture to show what happens as two Neon atoms approach each other and use it to help explain why two atoms are attracted to each other and how the changes in these atoms provides the mechanism (the process by which it occurs). Include annotations to support interpretation of your drawing.

What quantity of energy is required to break up one mole of SO2, and do its constituent elements 

1. Given the following information, calculate the lattice energy for LiI(s). Show all work and construct a diagram(cycle) that shows each step in the process of forming LiI(s) from gaseous ions.

A is -1214 Ethen 23.molar mass

The synthesis of Hansa yellow dye takes place in a series of two steps. On Sunday June 9th, 1996 a violent runaway reaction occurred causing very significant damage to equipment and buildings. After a detailed analysis, the plant was rebuilt, and production resumed. What is the enthalpy of the overall reaction? Show work for credit. Can you explain which of the two steps was most likely to blame for the incident? Step 1: CsH;CIN2O2(aq) + NANO2(aq) + 2HCI(aq) → C6H3CIN3O2*(aq) + Cl(aq) + 2H2O(I) + NaCI(aq) AH1 = -1212 kJ/mol Step 2: C6H3CIN3O2*(aq) + Cl'(aq) + C10H10CINO2(aq) → C16H12C12N4O4(aq) + HCl(aq) AH2 = 637 kJ/mol %3| Overall Reaction: C6H5CIN2O2(aq) + NaNO2(aq) + HCI(aq) → 2H2O(1) + NaCI(aq) + C16H12CI2N4O4(aq) AHrxn = ? kJ/mol %3D

An ammonia refrigeration cycle involves the conversion of 0.56 kg of liquid ammonia into vapor every minute at the boiling-point temperature. At what rate does the ammonia absorb energy?

Which of the following statements regarding atomic Br and Cl is FALSE? O Atomic Br is more efficient at catalytically destroying ozone than atomic Cl in the stratosphere due to a relatively higher proportion of the Br atoms being in a catalytically active form at any given time.

The reaction of CH3OH(g) with N2(g) to give HCN(g), NH3(g), and O2(g) requires 164 kJ/mol of CH3OH(g). Write a balanced chemical equation for this reaction. Include the phases of all species in the reaction.  How much heat is involved in the reaction of 65.0 g of CH3OH(g) with excess N2(g) to give HCN(g) and NH3(g) in this reaction?

The steps of the Born-Haber cycle are shown for the ionic compound MX2, made up of generic metal M and generic, gaseous halogen X. Identify the overall reaction and identify the name of the enthalpy change for each reaction.

A large natural gas-fired electrical generating station may burn 0.5 kg of methane per second. Use standard enthalpies of formation to calculate the change in mass that occurs if the power station operates for 24 hours.
