Four properties of water are listed. It reacts with halogens to form oxygen gas as one of the products. It is transparent and tasteless in its pure form. It freezes at a temperature of 0 °C and lower. It decomposes to form hydrogen and oxygen. Which are the chemical properties of water?

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

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.

im pretty sure its b
