- The normal freezing point of n-octane 1C8H182 is -57 °C. Is there any temperature at which liquid n-octane and solid n-octane are in equilibrium? Explain.arrow_forwardUse the letter ‘A’ to label the line that gives the conditions for equilibrium between solid and liquid phases of bromine, the letter ‘B’ to label the curve that gives the conditions for equilibrium between liquid and vapor phases of bromine, and the letter ‘C’ to label the curve that gives the conditions for equilibrium between solid and vapor phases of brominearrow_forwardhe following reaction illustrates the decomposition of hydrogen peroxide (H2O2) to form water and oxygen gas:2 H2O2 (l) → 2 H2O (l) + O2 (g)When this reaction is carried out, 0.50 L of O2 gas is collected over water at a total pressure of 1.05 atm. The temperature is 23°C. The vapour pressure of water at this temperature is 0.0278 atm.What was the mass (in g) of the hydrogen peroxide that decomposed?arrow_forward
