The enthalpy of an intermediate step should be manipulated when used to produce an overall equation by using the Hess's law. You could multiply the enthalpy by -1 if this equation is reversed in theory.
Answer:
9.519e^-2
Explanation:
To accurately show the number in scientific notation, you need to move the decimal place to the left 2 spaces. Because you are moving the decimal place to the left, the exponent will be a negative number. Because the decimal place moves 2 units to the left, the exponent will be a -2.
Therefore, the answer in correct scientific notation is:
951.9 ----------> 9.519e^-2
