The position of a 25 kilogram pumpkin is carefully recorded. the pumpkin is then left outside for 24 hours. when the observer returns, the pumpkin has not moved. which word best explains the behavior of the pumpkin? a) deceleration b) inertia c) momentum d) oxidation

Calculate the enthalpy of the following reaction: 4 b (s) + 3 o2 (g) → 2 b2o3 (s) given the following pertinent information: (a) b2o3 (s) + 3 h2o (g) → 3 o2 (g) + b2h6 (g), δhoa = +2035 kj (b) 2 b (s) + 3 h2 (g) → b2h6 (g), δhob = +36 kj (c) h2 (g) + latex: \frac{1}{2} 1 2 o2 (g) → h2o (l), δhoc = −285 kj (d) h2o (l) → h2o (g), δhod = +44 kj
