Compare and contrast the moon and the moons of other planets.

The Moon of the Earth has some similarities, but also lot of differences with the other natural satellites in the Solar system.

The Moon is rocky, covered with dust, has lot of craters from asteroids and meteorites. Most of the planets in the solar system are actually gassy, frozen, and the craters tend to be very rare.

Compared to the planet around which it spins, the Earth, the Moon is actually very large, even though it is nowhere as large as some other moons in the Solar System. All the other moons tend to be much smaller in comparison the the planets around which they spin.

The Moon also has very low gravitational pull and very small mass for its size, and the reason for that is still not clear. All the other moons have gravitational pulls and masses that are expected by their size.

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 dissolution of polymer can be thermodynamically described in 2 steps.
