Glycerol (hoch2chohch2oh) is used in cosmetics. do you expect its viscosity to be larger or smaller than the viscosity of ethanol, ch3ch2oh? why or why not?

Glycerol is predicted to have a higher viscosity. Glycerol is a larger molecule with more instances of hydrogen bonding that lead to stronger intermolecular forces between molecules compared to ethanol.

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.

if you mean hydrogen and oxygen then water is the product
