288g of water at 24oC come in contact with steam at 100oC. As a result, the temperature of both substances equilibrate at 79oC. Determine the mass of steam that must have been condensed as a result of this process.

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.

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?
