is this correct Certainly! Let’s complete the table. Here are the initial number of moles for each substance:

Initial moles of C8H18: 5.60
Initial moles of O2: 7.60

Now, let’s calculate the moles used or formed for each substance:

Moles used or formed for C8H18: −5.60

Moles used or formed for O2: −7.60

Moles used or formed for CO2: +5.60

Moles used or formed for H2O: +7.60

Yes, that is correct. These calculations show the change in moles for each substance during the reaction.
