I believe it is <span>d. the bonds of both the reactants and the products are formed.</span>
1st and 4th options are suitable answers, as these 2 changes are not exactly physical changes as it cant return back to original form and as well as its not cooling, so I feel its 1st and 4th options
The name of that product is 1-nonene.
The sufix ene is because it is an alkene, which comes from the fact that it has a double bond.
The prefix none is because it has 9 carbon.
And the use of number 1 is because the double bond is in the carbon number 1.
To find moles : moles= Mass (C₄H₂O₄) / RFM (C₄H₂O₄)
so moles = 147.7 / 114 = <span>1.2956mol
hope that helps </span>
