the heat of this reaction,Na + 1/2 Cl 2 NaCl, is 98.3 kcal/mole what is the heat given off two moles of NaCl are formed ?
if the heat is 98km /moleNaCl, twice that is the heat for two moles NaCl
To calculate the heat given off when two moles of NaCl are formed, we can use the given information about the heat of reaction.
The balanced equation for the reaction is:
2 Na + Cl₂ → 2 NaCl
Given that the heat of reaction is 98.3 kcal/mole, we can interpret this as the heat released when one mole of NaCl is formed.
Therefore, to calculate the heat released when two moles of NaCl are formed, we can simply multiply the heat of reaction by the number of moles of NaCl:
Heat released = Heat of reaction x Number of moles of NaCl
Heat released = 98.3 kcal/mole x 2 moles
Heat released = 196.6 kcal
Therefore, when two moles of NaCl are formed in this reaction, the heat released is 196.6 kcal.
