Assuming a temperature of 500 K and expansion against 1. atm of pressure, how much work, in joules, can be done by the system if the octane is completely converted to carbon dioxide and water vapor. What will the enthalpy change be for the process
Bonding in some solids does not fit neatly into one of the four categories. Explain why the bonding in Na2CO3 is not purely ionic.
Complete and balance the following chemical equation using the smallest whole number coefficients. Assume the reaction takes place in acidic aqueous solution. Use H + to balance charge, not H 3 O +
Aluminum forms a layer of aluminum oxide when exposed to air which protects the bulk metal from further corrosion.
