Sodium (Na) metal undergoes a chemical reaction with chlorine (Cl) gas to yield sodium Cl, or common table salt. If 1.00 g of sodium reacts with 1.54 g of chlorine, 2.54 g of sodium chloride is formed and 17.9 kJ of heat is released. How much sodium and how much chlorine is grams would have to react to release 171 kcal of heat?

  • chemistry - ,

    171kcal * 2.54g NaCl/17.9kcal = 24.26g NaCl

    Now divide that up into the required 1:1.54 ratio to get the amount of each

  • chemistry - ,

    I don't understand what you mean by dividing it into the required ratio. I understand where you got the ratio from, but do you mean 24.26/1.00 = for sodium and 24.26/1.54 = for chlorine?

  • chemistry - ,

    I don't understand the question because when sodium and chlorine reacts they form an aqueous solution

  • chemistry - ,

    Sodium metal undergoes
