A nurse is assessing a 60-year-old client who reports increasing fatigue, joint pain, and swelling in both hands and wrists. The client states, “My joints feel so stiff when I wake up, but it gets after a couple of hours.” Based on these findings, which physical assessment finding should the nurse expect?

Use bond energies to calculate the ΔHrxn for the reaction: XeF2(g) + F2(g) → XeF6(g) Bond Bond Energy (kJ/mol) Xe−F 147 F−F 159

Place the following in order of increasing magnitude of lattice energy:  CaS        MgO        SrSe

Calculate the heat associated with the combustion of 115.0 g of propane, C3H8? The ∆H°rxn is -2044 kJ/mol.

Consider again the interpreter from Project 3, which given the program          let add = lam x {lam y {x + y} }      in let f = add @ 2      in let g = lam x {f @ x}      in g @ 7    end end end will return a list containing one number. Which? 

Calculate the heat associated with the combustion of 135.0 g of propane, C3H8? The ∆H°rxn is -2044 kJ/mol.

Place the following in order of decreasing magnitude of lattice energy: NaF      CsI       KCl

Consider the language from Project 2. Write the list that is the result of interpreting, on the input list [5; 2; 4], the program       var x; var w; input x; input w; output (x + w); output (x – w)

Consider the interpreter from Project 3, which given the program         let b = lam x {x * 2}         in b @ 3 + 1 end will return a list containing one number. Which?

Consider again the interpreter from Project 3.  Can it interpret a definition of a recursive function, such as the factorial function? Possible answers are: A1: yes, just write    let fact = lam n     {if n {n * fact @ (n – 1) } { 1 }}   in fact @ …  end A2: yes, by defining a certain combinator Z and then write   let Fact = lam f {lam n      { if n {n * f @ (n – 1) } { 1 }}} in    Z @ Fact @ …    end end A3: no, the interpreter cannot handle recursion and will complain about the function Which one is correct:
