For which the following reaction, the enthalpy of the reaction is equal to the enthalpy of the formation of the products.
00:11
So for the enthalpy formation of the products, we know basically the reaction has to be like a plus b equals to ab, something like that.
00:25
Basically you have the single element substance of the compound.
00:34
So which one is that? so first, the sodium reacts with 12 fluorine, it forms sodium fluoride.
01:01
Apparently this reaction is not balanced, so this is not the right answer.
01:06
Same as the second one, sodium reacts with 12 fluorine gas, it becomes sodium fluoride.
01:16
Both of them are not balanced.
01:19
And third one, co reacts with o2, forms co2.
01:26
And apparently the co is not a single element substance, so this definitely does not represent the formula.
01:40
And the fourth one, carbon, which is graphite, reacts with oxygen, forms co2...
