Hm.. do you have a picture or something so I could help you.
Answer:
The enthalpy of the reaction is 64.9 kJ/mol.
Explanation:
..[1]
..[2]
..[3]
..[4]
2 × [2] - [1]- [3] = [4] (Using Hess's law)
The enthalpy of the reaction is 64.9 kJ/mol.
The balanced chemical reaction that would occur here would be:
7O2 + 2 Cl2 --> 2 Cl2O7
To determine the moles of oxygen that is needed in the system, we use the given amount of the product that is needed to be produced. Then, we use the relation from the balanced reaction to relate the product and one of the reactants. We do as follows:
moles Cl2O7 = 60.7 mol
moles O2 = 60.7 mol Cl2O7 ( 7 mol O2 / 2 mol Cl2O7 )
moles O2 = 212.45 mol O2
Therefore, about 213 moles of oxygen gas is needed in order to producr 60.7 moles of dichlorine heptoxide.
The object can no longer be returned to its original self, like ashes can't turn back to wood. The color changes, and bubbles.Also odor change, and gas formation.
