Can bromine liquid oxidize water to oxygen gas under standard conditions? Why or Why Not?
When styrene C8H8 burns in oxygen to form carbon dioxide and liquid water under standard-state conditions at 25°C, 42.62 kJ are released per gram of styrene. Find the standard enthalpy of formation of styrene at 25°C. (Given: ΔH°f[CO2(g)] = –393.5 kJ/mol, ΔH°f[H2O(l)] = –285.8 kJ/mol)
Hydrogen gas, H2, and oxygen gas, O2, can be reacted to form liquid water. If 2.00 g hydrogen gas and 17.20 g oxygen gas are reacted in a 1.500 L flask at 25.0 °C, calculate the total gas pressure (atm) in the flask at 25 °C. The vapor pressure of water is 23.8 mm Hg. Stoichiometry is involved in this question. Total gas pressure:

Hydrazine (N2H4) is a liquid that burns in oxygen gas to yield nitrogen gas and water vapor. Using the data below, determine the ΔG and the equilibrium constant for the combustion reaction. Chemical ΔGfº (kJ/mol): [N2 (g)=0] [N2H4 (l)=149] [N2H4 (g)=159] [H2O (l)=-237] [H2O (g)=-229] [O2(g)=0] I got that ΔG is -607, but why does K=e^245?
An aqueous solution of hydrogen peroxide (H2O2) decomposes to oxygen gas and liquid water. If the rate of disappearance is -4.06 M/s, what is the rate of formation of Oxygen gas for this reaction?
Liquid water can be split into hydrogen gas and oxygen gas (ΔH = 285.8 kJ/mol) by applying energy through an electric current. In this experiment, 13.31 kJ of energy are applied to 12.3 grams of water in a sealed reaction vessel whose volume is 4.56 L and whose temperature is 311.15 K Note: At 311.15 K, the vapor pressure of water is 0.0654 atm. (a) Is this reaction exothermic or endothermic? (b) Write a balanced chemical equation for this reaction. Be sure to...
