What is the best example of potential energy?

Chemistry
1 answer:
MrRissso [65]3 years ago
3 0

Answer:

When an archer pulls back the bowstring, some amount of elastic potential energy is gained by the flexible limbs of the bow. The more an archer pulls back, the more potential energy will be gained by the limbs of the bow due to stretching. When the bowstring is released, the arrow moves forward very quickly. What happens here is that the potential energy that is gained by the bow due to stretching is being quickly transferred to the arrow in the form of kinetic energy, and so, it moves forward.

Answer:

Anabolic Reaction : Photosynthesis

Occurs in plant life : Both

a way to store energy : Both

Catabolic Reaction : Cellular Respiration

a way to release energy : Both

involves oxygen and carbon dioxide : oxygen releases by the process of photosynthesis. Oxygen is involved in areobic respiration and not in anarobic respiration.

Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in
Evgesh-ka [11]

Which mathematical relationship allows calculation of the equilibrium constant of a reaction if you know the standard change in Gibbs Free Energy ΔG is related to Q by the equation ΔG=RTlnQK. If ΔG < 0, then K > Q, and the reaction must proceed to the right to reach equilibrium

<h3>What is Gibbs Free Energy?</h3>

The maximum amount of work that may be accomplished by a thermodynamically closed system at constant temperature and pressure can be determined using the Gibbs free energy (also known as Gibbs energy; symbol: displaystyle G). Additionally, it offers a prerequisite for any processes like chemical reactions that might take place in such circumstances.

The maximum amount of non-expansion work that can be taken from a closed system (one that can interchange heat and work with its surroundings but not matter) at fixed temperature and pressure is known as the Gibbs free energy change, which is measured in joules in SI. This maximum is only possible with a fully reversible method.

If 309 grams of potassium combines with 228 g chlorine gas, how many grams of the single product will be formed? What are the LR
lisov135 [29]

The amount of KCl that would be formed will be 478.8 grams

<h3>Stoichiometric calculations</h3>

From the equation of the reaction, the mole ratio of K to Cl_2 is 2:1.

Mole of 309 g potassium = 309/39 = 7.92 moles

Mole of 228 g Cl2 = 228/71 = 3.21 moles

Thus, potassium is in excess while Cl2 is limiting.

Mole ratio of Cl2 and KCl = 1:2

Equivalent mole of KCl = 3.21 x 2 = 6.42 moles

Mass of 6.42 moles KCl = 6.42 x 74.55 = 478.8 grams
