what are the advantages of patient roles

At 0 degrees celcius, a 1.0 L flask contains 5.0 x 10^-2 mol N2, 1.5 x 10^2 mg O2, 5.0 x 10^21 molecules NH3. Calculate the partial pressure of each gas and what is the total pressure in the flask. How do I calculate this?

Na (s) + 1/2F2 (g) = 2NaF (s) Are the reactants at higher or lower energy than the products and is the reaction endothermic or exothermic? I feel that the reaction is exothermic, but can't determine higher or lower enery?

The electronegativities of the elements are H=2.1, O=3.5, F=4.0, S=2.5, Cl=3.0. Determine (calculate) the electronegativity diffrences for the following molecules and explain how they are arranged in the order: H2, O2, HCl, HF, H2O and position them in th...

Which statement describes how geography influenced the cultural development of Southeast Asia? A. Open seas protected the indigenous cultures of the island nations from outside influence. B. Distance from Oceania prevented the migration of Austronesian la...

A rock is thrown straight up into the air with an initial speed of 53 m/s at time t = 0. Ignore air resistance in this problem. At what times does it move with a speed of 40 m/s? Note: There are two answers to this problem. earlier time: later time:

Two aircraft approaching an aircraft carrier are detected by radar. The first aircraft is at a horizontal distance of 34.2 km in the direction 44.0° north of east and has an altitude of 2.36 km. The second aircraft, at half this altitude, is at a horizont...

roles that patients play in health care setting, thanks.

thank you for your help

Thank you Ms. Sue! :-)

Im am bit confused, why should I extend it to 3 dimensions? I can see it mentions a Z axis but the exercise only mentions 2 aircrafts, I can't seem to find enough information for it.
