The energy conversions in the Rude Goldberg device design is as follows:

a quartz falls off from the roof: potential to kinetic
the quartz hits and lift a soda bottle: kinetic to potential
The soda bottle moves hits a battery: potential to kinetic
a battery which slides along into a torch that lights up: chemical to light

<h3>What is a Rube Goldberg device?</h3>

A Rube Goldberg device uses a set of reactions that work in succession with one event triggering the next event in the form of a chain reaction until the final event is completed.

The Rude Goldberg device design is as follows:

The design is of a unit that produces light when a quartz falls off from the roof. It then hits a plastic soda bottle and its velocity is converted into potential energy used to lift a soda bottle. The soda bottle then on rising hits a battery which slides along into a torch which then light up.

In conclusion, Rude Goldberg devices shows various forms of energy conversion.

What is a chemical equilibrium?

a_sh-v [17]

Answer:

Explanation:chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

The coefficients in front of H⁺ and Fe³⁺ in the balanced reaction is 8 and 5.

<h3>What is a redox reaction ?</h3>

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.

An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

Fe²⁺ +MnO₄⁻ ⇄ Fe³⁺ + Mn²⁺

Assigning Oxidation numbers

Fe²⁺ : +2

+Mn : + 7 O₄⁻ : -2

Fe³⁺ : +3

Mn²⁺ : +2

Oxidation half reaction Fe²⁺ -----> Fe³⁺ +e-

Reduction half reaction MnO₄⁻ + 5 e⁻ ----> Mn²⁺

After balancing the charge & oxygen atoms

5Fe²⁺ -----> 5Fe³⁺ +5e-

MnO₄⁻ + 5 e⁻ +8H⁺ ----> Mn²⁺ +4H₂O

After adding half reaction

5Fe +MnO₄⁻+8H⁺ ⇄5Fe³⁺ +Mn²⁺ +4H₂O

This is the final balanced reaction.

The coefficients in front of H⁺ and Fe³⁺ in the balanced reaction is 8 and 5.

What is the equilibrium expression for this reaction?

Misha Larkins [42]

Answer:

B

Explanation:

The equilibrium expression is

[products]/[reactants] and each is raised to its molar coefficient.

So:

[H2}^2[O2]/[H2O]^2
