Oxygen at 1 atm. pressure and 0C has a density of 1.4290 gm/L. root mean square speed would be:

For which one of the following reactions is the value of δh° rxn equal to δh° f for the product? a. 2 h2 (g) + o2 (g) → 2 h2o (l) b. n2 (g) + o2 (g) → 2 no (g) c. 2 h2 (g) + o2 (g) → 2 h2o (g) d. h2o (l) + 1/2 o2 (g) → h2o2 (l) e. none of the above

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

What happens to isotopes that are unstable?
