A sample of oxygen occupies .560L when the pressure is 1.05atm. At constant temperature, what volume does the gas occupy when the pressure decreases to .92atm?

Measuring which physical property is most likely to produce the most precise results when trying to identify a substance

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

What determines the average kinetic energy of the particles in a gas? a. the number of collisions b. the number of particles c. the size of the particles d. the temperature
