Given 1.67 moles of K, how many moles of KBr are produced?
2 K+ 1 Br2---> 2 KBr

If 0.414 g of hydrogen is obtained in this experiment how many grams of sulfur must be obtained

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct

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.
