Calculate the energy needed to produce 10 moles of Cl2O7 using this balanced equation.
2Cl +70+ 100kCal==2ClO7
please explain steps
if I needed to calculate for 7 moles, how would it change?
I think you have made one or more typos in your equation. I will assume the equation should be
2Cl + 7 O + 100 kcal => Cl2O7
If it takes 100 kcal for 1 mol then it will take 100 x 10/1 = ? kcal.
What would it take for 7. Can you handle that?
To calculate the energy needed to produce 10 moles of Cl2O7 using the given balanced equation, you can follow these steps:
1. Identify the coefficients of the balanced equation:
The balanced equation shows that 2 moles of Cl2 react to form 2 moles of ClO7.
2. Calculate the energy change for the reaction:
The given equation states that the energy change is 100 kcal for the formation of 2 moles of ClO7.
Since 2 moles of ClO7 are produced in the reaction, the energy change for the formation of 1 mole of ClO7 is 100 kcal / 2 moles = 50 kcal.
3. Calculate the energy change for the formation of 10 moles of ClO7:
To calculate the energy change for the formation of 10 moles of ClO7, you need to multiply the energy change for 1 mole (50 kcal) by 10:
Energy change = 50 kcal/mole * 10 moles = 500 kcal
Therefore, the energy needed to produce 10 moles of Cl2O7 is 500 kcal.
If you needed to calculate the energy needed to produce 7 moles of Cl2O7, you would follow a similar approach:
1. Identify the coefficients of the balanced equation:
The balanced equation still shows that 2 moles of Cl2 react to form 2 moles of ClO7.
2. Calculate the energy change for the reaction:
The given equation states that the energy change is 100 kcal for the formation of 2 moles of ClO7.
Since 2 moles of ClO7 are produced in the reaction, the energy change for the formation of 1 mole of ClO7 is 100 kcal / 2 moles = 50 kcal.
3. Calculate the energy change for the formation of 7 moles of ClO7:
To calculate the energy change for the formation of 7 moles of ClO7, you need to multiply the energy change for 1 mole (50 kcal) by 7:
Energy change = 50 kcal/mole * 7 moles = 350 kcal
Therefore, the energy needed to produce 7 moles of Cl2O7 is 350 kcal.
