How many grams of sodium chloride should be used in compounding
the following prescription:
Rx
Phenacaine HCl 1%
Chlorobutanol 0.5%
Sodium Chloride qs
Purified water ad 60 mL
Make isotonic solution
Sig. one drop in each eye.
MW of Phenacaine HCl = 353, i factor = 1.8
MW of chlorobutanol = 177, i factor = 1.0
MW of sodium chloride = 58.5, i factor = 1.8
0.9% sodium chloride solution is isotonic with body
fluids

This reaction has an equilibrium constant of K = 2.2 x 10^6 at 298 K.
2COF2(g) ⇌ CO2(g) + CF4(g)
Calculate K for each reaction and predict whether reactants or products will be favored at equilibrium.
a) COF2(g) ⇌ 1/2CO2(g) + 1/2CF4(g)
b) 6COF2(g) ⇌ 3CO2(g) + 3CF4(g)
c) 2CO2(g) + 2CF4(g) ⇌ 4COF2(g)

A molecule or ion that donates the hydrogen in a hydrogen bond is a hydrogen bond donor A molecule or ion that binds to this hydrogen is a hydrogen bond acceptor. Specify the hydrogen bonding behavior of the 4 species below by selecting:
donor for species that act as donors only
acceptor for species that act as acceptors only
both for species that act as both donors and acceptors
neither for species that act neither as donors nor as acceptors.

Imagine a hypothetical atom that has only four allowed energy levels: a ground state with energy E1 and three excited states with progressively higher energies of E2, E3, and E4. When heated, this atom is observed to emit radiation of six different frequencies A-F. These frequencies are listed in the table below. Please complete the table:
