The distribution or scatter of bones at a crime scene gives no indication about the time of death.
true or false?

The given statement is false.

Explanation:

scattering or distribution of bones at crime scene will not give any idea or indication about the time since death.This is because in order to estimate the time since death skeleton of body must be intact along with biological parts like skin tissues, muscles, organs etc.

The biological degradation of the these parts of the human body will give rough estimate of time since death.

Where from estimation of time since from death from bones is not impossible.

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.
