Use the following reaction: C4H9OH NaBr H2SO4 C4H9Br NaHSO4 H2O If 15.0 g of C4H9OH react with 22.4 g of NaBr and 32.7 g of H2SO4 to yield 17.1 g of C4H9Br, what is the percent yield of this reaction

Combustion of ethylene glycol leads to a change in internal energy (/DeltaU) of - 1189 kJ at 298 K. What is the corresponding change in enthalpy in kJ/DeltaH? HOCH_2CH_2OH (l) + 5/2 O_2 (g) → 2 CO_2 (g) + 3 H_2O (l) / DeltaU = - 1189 kJ

When the fluid cools, the kinetic energy of the inolecules decreases. This causes the molecules to slow down and move closer together. Sines the molecules are closer together, the density of the fluid increases and the fluid sinks.
