Synthesis of hexane-3,4-diol from trans-3-hexene may be accomplished in two ways: (i) OsO4 hydroxylation & (ii) C6H5CO3H epoxidation followed by NaOH(aq) opening of the epoxide ring. Which of the following statements about the products from these reactions is correct? A. two different isomers are formed, but both are chiral
B. the two methods give the same product
C. (i) gives an achiral isomer, (ii) gives a chiral isomer
D. (i) gives a chiral isomer, (ii) gives an achiral isomer

answer: the enthalpy of the overall chemical reaction is +87.88 kj or +88 kj.

according to hess's law, the overall enthalpy of a reaction is the difference between the sum of enthalpy values of all the products and the sum of enthalpy values of all the reactants.

δh(reaction) = ∑nδh(products) - ∑nδh(reactants)

δh(reaction) = [δh +δh] - [δh]

δh(reaction) = [1(-287.02) + 1(0) ] - [1(-374.9)] kj = +87.88 kj

here, δh (pcl3) = -287.02 kj, δh(cl2) = 0, δh(pcl5) = -374.9 kj

therefore, enthalpy of the overall reaction is +87.88 kj or +88 kj.

the answer is 303.15 or 303

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
