Homogeneous reaction conditions have some advantages over heterogeneous reactions (such as the biphasic Oxidation of Borneol lab described in the lab manual).

For example, efficient stirring may not be as critical. Isopropanol (i. e. 2-propanol) is an organic solvent that is miscible with water.

Imagine someone proposed using isopropanol instead of ethyl acetate as the organic solvent as a possible improvement to the experiment.

Why would that be a bad idea? There is a very specific reason to expect that this would not work, so your answer should be specific.

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.

ill try to . no promises tho.

explanation:

i don,t know so just answer mine

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
