A weather balloon was launched from a research station at Anderson Air Force Base on the island of Guam (standard pressure). When the balloon was launched, the temperature
was 24 °C and the volume of the balloon was 14.8 m2. At an altitude of 11 000 meters,
the volume of the balloon had increased to 50.0 m and the temperature had dropped to
-56 °C. What was the pressure in atmospheres of the balloon at that altitude?

The diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
