Jovian planets are what we call the "gas giants," so immediately we can eliminate craters or volcanos because they don't have a solid surface. asteroids in space doesn't belong to any specific planet, so the answer is ring systems.

Present in a state where it molecules are far apart during a change of state it's molecules slow down which change of state has
blagie [28]

Answer:

The change of state that has occurred is from a gas to a liquid

<em>Note: The question is incomplete. The complete question is given blow.</em>

<em>H₂O is initially present in a state where its molecules are far apart. During a change of state, its molecules slow down. Which change of state has most likely taken place? </em>

<em>from a gas to a liquid </em>

<em>from a liquid to a gas </em>

<em>from a solid to a liquid </em>

<em>from a gas to a plasma</em>

Explanation:

Water can exists in three states: as gaseous water vapor, as liquid water, and as solid ice. Each of these states of water can be interconverted from one to another by the addition or removal of heat in a process known as change of state.

Liquid water can be converted to solid ice by the removal of heat, while solid ice ice can be converted to liquid water by the addition of heat. Also, liquid water can be converted to water vapor by the addition of heat, while water vapor can be converted to liquid water by the removal of heat.

Of the three states of water, the one in which the molecules are farthest apart is in the gaseous state. The molecules have high kinetic energy and move randomly while colliding with one another. When a heat is removed from these highly energetic molecules, the molecules slow down and lose some of their kinetic energy and a change of  occurs from gaseous to liquid state.

Therefore, the change of state that occurred as described, is from gas to liquid.

One application of Hess's Law (which works for ΔH, ΔS, and ΔG) is calculating the overall energy of a reaction using standard en
VikaD [51]

Answer:

The standard change in free energy for the reaction =  - 437.5 kj/mole

Explanation:

The standard change in free energy for the reaction:

                              4 KClO₃ (s) → 3 KClO₄(s) + KCl(s)

Given that   ΔGf(KClO3(s)) = -290.9 kJ/mol;

                    ΔGf(KClO4(s)) = -300.4 kJ/mol;

                    ΔGf(KCl(s)) = -409 kJ/mol

According to Hess's law

ΔGr (Free energy change of reaction)= ∑(Product free energy - reactant free energy)

               ⇒ ΔGr⁰ = {3 x (-300.4) + (-409)} - {3 x (- 290.9)}

                            = - 901.2 - 409 + 872.7

                            =  - 437.5 kj/mole
