The potential energy of the molecules changes during a reaction.

Potential energy is a form of energy that is stored but is dependent on the relative positions of different system components. Stretching or compressing a shock absorber increases its potential energy. A steel ball has more potential energy when it is raised above the surface of the earth than when it is brought to Earth.

Potential energy can be transformed into kinetic energy, which is the energy of motion, and then into other forms like electric energy. One of the two types of energy is potential energy, which is the latent energy in an object at rest. Kinetic energy, on the other hand, is the energy that a moving object expresses.

There are many contributions that all the mentioned fields have made to the development of chemistry.

When you hear the word "alchemy," you might picture witches watching a pot of boiling liquid or sorcerers working in smokey labs or disorganized libraries. Despite these associations with myth and mysticism, alchemical observations claim to have played a significant part in the advancement of modern science.

In the past, alchemy referred to any study of nature. was an ancient philosophical and theological discipline that merged metalworking and chemistry. Physics, medicine, astrology, mysticism, spiritualism, and art were all included in alchemy.

Alchemy was a sacred practice as well as a scientific discipline. Many of its practitioners have altruistic motives. For instance, alchemists may be able to cleanse humans if they discover the secret to "purifying" base metals into gold. At the same time, alchemy has historically been associated with get-rich-quick schemes and plenty of alchemists have been exposed as frauds and impostors.

Nevertheless, a few alchemists were significant practitioners whose work laid the foundation for modern chemistry and medicine.

Therefore, there are many contributions that all the mentioned fields have made to the development of chemistry.

The percent of the yield of this reaction is 106.7 grams or 72.3%.

The reaction in question is a decomposition reaction. A decomposition reaction is a reaction in which a compound is broken down by the action of heat, light or electrical energy to produce two or more new substances. Here, potassium chlorate decomposes into potassium chloride and oxygen gas. This is the first part of the answer. This 0.506 mol of KCL is formed when 62 g of KCL 03 of Part B is reacted.

To express the efficiency of a reaction the percent yield can be calculated using the following formula: % Yield = Actual Yield/Theoretical Yield x 100. Percent Yield of 90% Rates means 90% and 10% responses. % of material that was efficient was wasted did not react or product was not captured. The yield rate is the difference between the actual amount of product produced and the calculated maximum yield. The formula for percent yield is the experimental yield divided by the theoretical yield and multiplied by 100.

The frequency of this radiation of a quantum of energy 4.14 *10-14 J is calculated to be 2.58 *10-15 Hz.

The Photoelectric Effect occurs when electrons are released from a metal surface when light strikes it. It was once thought that the greater the intensity of incoming light, the greater its energy, independent of hue. The light was viewed and treated as a wave, however, the wave phenomenon could not explain light's photoelectric actions.

The Quantum, according to Max Planck, is the smallest unit of energy that is released or absorbed in the form of electromagnetic radiation. The energy released or absorbed is proportional to the frequency of the radiation. It may be expressed mathematically as:

E= hc/λ

or

E= hf        ( because, f = c/λ)

where,

E= Energy of the particle

h= Planck's constant

c= speed of light

λ= wavelength of the particle

f = frequency of the radiation

Thus, E= hf

Given,

E = 4,14*10-14J

E= 1.71017356 * 10^20 eV

h= 6.626 *10-34 m2Kg/s

E=hf

f= E/h

f= (1.71017356 * 10^20 eV) / (6.626 *10-34 m2Kg/s)

f= C

Thus, the frequency of this radiation is 6.626 *10-34 m2Kg/s.

a. The limiting reactant is silver nitrate

b. The theoretical yield of silver chloride is 37.94 grams

c. The percent yield of silver chloride is 88.3%

First, let us see the equation of the reaction:

[tex]HCl + AgNO_3 -- > HNO_3 + AgCl[/tex]

The mole ratio of the reactants is 1:1.

Mole of 45 g sample of silver nitrate = 45/170

                                                = 0.2647 moles

Mole of 55 g sample if hydrochloric acid = 55/36.46

                                                = 1.5068 moles

Thus, the limiting reactant is silver nitrate.

Mole ratio of silver nitrate and silver chloride = 1:1.

Equivalent mole of silver chloride = 0.2647 moles

Mass of 0.2647 moles silver chloride = 0.2647 x 143.32

                                                              = 37.94 grams

Theoretical yield of silver chloride = 37.94 grams

The percentage yield of silver chloride = 33.5/37.94 x 100

                                                         = 88.3%

The volume of the solution in milliliters, given the data from the question is 104.8 mL

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

We'll begin by obtaining the mole of CuNO₃ in the solution. This is illustrated below:

Mole = mass / molar mass

Mole of CuNO₃ = 6.58 / 125.55

Mole of CuNO₃ = 0.0524 mole

Molarity = mole / Volume

0.5 = 0.0524 / volume

Cross multiply

0.5 × volume = 0.0524

Divide both sides by 0.5

Volume = 0.0524 / 0.5

Volume = 0.1048 L

Multiply by 1000 to express in milliliters

Volume = 0.1048 × 1000

Because it is buoyant, helium floats because its molecules are lighter than those of our atmosphere's nitrogen and oxygen and so they rise above it.

The helium balloon moves some air around (just like the empty bottle displaces an amount of water). The balloon will float in the air as long as the combined weight of the helium and balloon fabric is less than the air it replaces. Helium is actually much lighter than air, as it turns out.

Two electrons, two protons, and typically two neutrons make up the element helium. It is an inert gas that has no color or smell. Fusion and fission both produce helium as a product. Helium was initially found in the sun's spectrogram in 1868.

The mass of nitrogen monoxide is 1.54 g.

In this case we have to make use of stoichiometry to obtain the mass of the NO that is produced in the reaction. The balanced reaction equation is;

[tex]4NH_{3} (g) + 5O_{2} (g) ---- > 4NO(g) + 6H_{2} O(g)[/tex]

Mass of ammonia= 1.55 g

Number of moles of ammonia =  1.55 g/17 g/mol = 0.088 moles

Mass of oxygen =  2.05 g

Number of moles of oxygen =  2.05 g/32 g/mol = 0.064 moles

If 4 moles of ammonia reacts with 5 moles of oxygen

0.088 moles of ammonia reacts with 0.088 moles *  5 moles/ 4 moles

= 0.11 moles

Hence oxygen is the limiting reactant.

If 5 moles of oxygen produces 4 moles of nitrogen monoxide

0.064 moles of oxygen produces 0.064 moles * 4 moles / 5 moles

= 0.0512 moles

Mass of nitrogen monoxide = 0.0512 moles * 30 g/mol = 1.54 g
