1. how many liters of chlorine gas, at standard temperature and pressure, will react with 15.5 grams of potassium metal? show all of the work used to solve this problem 2 k + cl2 yields 2 kcl 2. how many liters of methane gas (ch4) need to be combusted to produce 12.4 liters of water vapor, if all measurements are taken at the same temperature and pressure? show all of the work used to solve this problem. ch4 (g) + 2 o2 (g) yields co2 (g) + 2 h2o (g)

Use the standard enthalpies of formation for the reactants and products to solve for the δhrxn for the following reaction. (the δhf of c2h4 is 52.26 kj/mol, co2 is -393.509 kj/mol, and h2o is -241.818 kj.) c2h4 (g) + 3o2(g) 2co2 (g) + 2h2o(g) δhrxn = the reaction is .

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
