Choose all of the statements that correctly describe the movement of particles when thermal energy is added or removed.

a) the addition of thermal energy to a gas will increase the chance the particles will collide.
b) the particles in a solid are not in motion.
c) as you remove thermal energy from a liquid, the particles will begin to slow down.
d) the addition of thermal energy to any phase of matter (solid, liquid, or gas) will decrease the chance of particle collisions.
e) it is possible to add enough thermal energy to break the bonds between particles and change the state of matter.

1). The addition of thermal energy to a gas will increase the chance the particles will collide.

3). As you remove thermal energy from a liquid, the particles will begin to slow down.

5). It is possible to add enough thermal energy to break the bonds between particles and change the state of matter.

Explanation:

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.
