Gaseous chlorine (Cl2) disproportionates in water under basic conditions forming hypochlorous acid and hydrochloric acid. i) Clearly identify the chemical species that are oxidized and reduced. Justify your statements. ii) Write the oxidation and reduction half-reactions. iii) Write the balanced chemical reaction equation. iv) If the gaseous chlorine initially contained in a 1.5 L cylinder at 25°C and 1 atm is bubbled into water, how many moles of hypochlorous acid and hydrochloric acid will (theoretically) form? Assume that the reaction...

Consider a biochemical reaction under standard conditions. The change in enthalpy is -7 kJ/mol and the change in entropy is -25 JK^-1 mol^-1. Without doing any calculations, can you determine if the reaction is spontaneous? Calculate delta G^degree' for the reaction at 5 degree C. Is the reaction spontaneous or not? Why or why not? If not, does raising the temperature make the reaction more likely to be spontaneous, or less likely to be spontaneous?

ΔGf° = +38 kJ/mol for gaseous mercury under standard conditions. Write the balanced reaction for the production of gaseous mercury from liquid mercury. Also write the equilibrium expression for that reaction. What is the relationship between the equilibrium constant and the pressure of gaseous mercury? Use the Gibbs energy given above to calculate the vapor pressure of gaseous mercury under standard conditions.

What is the nuclear reaction occurring? Light nuclei (such as hydrogen) under high temperature combine to form a larger single nucleus (such as helium). An atom of one element is converted to an atom of another element. Like when a spontaneous emission of a beta particle causes a atom of lead-214 to change into bismuth-214. A heavy nucleus (such as the U-235 nucleus) splits into two or more parts. What are the differences between how a coal power plant and...
