Nitrogen and hydrogen combine at a high temperature, in the presence of a catalyst, to produce ammonia. N2(g) + 3 H, (g) → 2 NH, (g) There are four molecules of nitrogen and nine molecules of hydrogen present in the diagram. When the reaction is complete, how many molecules of NH3 are produced? What is the limiting reactant? molecules of NH3: O nitrogen O hydrogen How many molecules of each reactant are remain after the reaction is complete? molecules of H2: molecules of N2:

Which of the following statements is a feature of scaled particle theory? a) The work required to insert a solute into a solvent depends on the solute's volume only b) The work required to insert a solute into a solvent depends on the solute's accessible surface area only c) High molecular-weight compounds cross biological membranes more easily than low- molecular weight ones d) A large particle has the same surface area-to-volume ratio as a small particle e) Particles in solution pay an energetic penalty to create a cavity in the solvent

You have just started working in an Urgent Care Clinic as a nurse.  Mom brings in her 3 year old little boy, Brandon.  Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby!  He's also been pulling a lot at his right ear and sounds congested.  At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg.  Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips.  His temperature is 39C, other vitals signs are normal.  Though he looks ill he appears to be medically stable.  The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom.  The orders include:  push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…
