Balance the following chemical equation, then answer the following question. c8h18(g) + o2(g) → co2(g) + h2o(g) how many grams of oxygen are required to react with 10.0 grams of octane (c8h18) in the combustion of octane in gasoline?

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
