Is it possible to use the subatomic particles as an energy source?
So first, let's get some background knowledge.
So, how does energy concentrate to become subatomic particles?
To answer it in the best way possible, we have to understand what is energy and what particles are.
The capacity to perform labor is energy. It cannot be made or taken away. All of it was made during the moment of the Big Bang. Since then, it has changed into one form or another or has been employed to produce particles. In their purest form, elementary particles are quantum fields that are waves in space-time carrying energy. These waves also contain four moments (energy, vector momentum, angular momentum, and charge), unless they are completely chargeless like photons. They are nothing more than energy, which is dependent on the wave's frequency (and has endowed with it some properties like charge and spin etc). Therefore, energy creates particles by destroying one or more particles and creating one or more other particles, by taking energy from them and transducing into the others, in a similar fashion to how particles came out of nothing but energy pumped into the space-time the first time (after the Big Bang). In quantum physics, the annihilation and creation operators are used to represent it. I'll use one as an illustration. formation of the duo. Once it collides with a heavy nucleus (i.e., one with a high atomic number, Z), a high-energy gamma ray with energy greater than the rest energies of a proton-electron pair experiences an electromagnetic interaction, which is mediated by a virtual photon, and generates an electron and positron pair. For instance, if the initial gamma ray had an energy of 20 MeV, the generation of the pair would take around 1.022 MeV (the total of the rest energies of the electron and positron), whereas the pair would share about 18.078 MeV in kinetic energy. As a result, the energy is simply converted from a boson with no charge, mass, or spin to two products with opposite charges, each having a mass of 0.511 MeV: a negatively charged spin 1/2 fermion and a positively charged spin 1/2 fermion (anti-particle of the first).
So to answer, let's complete this in a question, what subatomic particle causes electricity?
There are instances when the protons and electrons in an atom's outermost shells are not strongly attracted to one another. It is possible to force these electrons out of their orbits. They may move from one atom to another by exerting force. Electricity is made up of these moving electrons.

When hydrogen sulfide gas is bubbled into a solution of sodium hydroxide, the reaction forms sodium sulfide and water. How many grams of sodium sulfide are formed if 1.50 g of hydrogen sulfide is bubbled into a solution containing 1.65 g of sodium hydroxide, assuming that the limiting reagent is completely consumed ?
Answer:
1.61 g Na₂S
Explanation:
To find the mass of sodium sulfide (Na₂S) generated from hydrogen sulfide (H₂S) and sodium hydroxide (NaOH), you need to (1) construct the balanced chemical equation, then (2) calculate the molar masses of each molecule involved, then (3) convert grams of each reagent to grams of the product (via the molar masses and mole-to-mole ratio from equation coefficients), and then (4) determine the limiting reagent and final answer. It is important to arrange the conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator).
(Step 1)
The unbalanced equation:
H₂S + NaOH ---> Na₂S + H₂O
Reactants: 3 hydrogen, 1 sulfur, 1 sodium, 1 oxygen
Products: 2 hydrogen, 1 sulfur, 2 sodium, 1 oxygen
The balanced equation:
H₂S + 2 NaOH ---> Na₂S + 2 H₂O
Reactants: 4 hydrogen, 1 sulfur, 2 sodium 2 oxygen
Products: 4 hydrogen, 1 sulfur, 2 sodium, 4 oxygen
(Step 2)
Molar Mass (H₂S): 2(1.008 g/mol) + 32.065 g/mol
Molar Mass (H₂S): 34.081 g/mol
Molar Mass (NaOH): 22.990 g/mol + 15.998 g/mol + 1.008 g/mol
Molar Mass (NaOH): 39.998 g/mol
Molar Mass (Na₂S): 2(22.990 g/mol) + 32.065 g/mol
Molar Mass (Na₂S): 78.045 g/mol
(Step 3)
1.50 g H₂S 1 mole 1 mole Na₂S 78.045 g
----------------- x ---------------- x -------------------- x ----------------- =
34.081 g 1 mole H₂S 1 mole
= 3.43 g Na₂S
1.65 g NaOH 1 mole 1 mole Na₂S 78.045 g
-------------------- x ---------------- x ----------------------- x ---------------- =
39.998 g 2 moles NaOH 1 mole
= 1.61 g Na₂S
(Step 4)
Because NaOH generates less product, it will run out before all of the H₂S is used. This makes NaOH the limiting reagent and the final answer 1.61 grams Na₂S.

• First calculate the number of moles in 3.66 × 10²³ :
no. of moles = number of particles / Avogadro's Number
= (3.66 × 10²³) / (6.022 × 10²³)
= 0.6078 mol
• Now use the following equation to calculate the molar mass:
Molar mass = mass of substance / no. of moles
= 24.31 / 0.6078

What is an ideal gas equation?The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Stoichiometric calculations:
[tex]C_3H_8(g) + 5 O_2(g)[/tex]→ [tex]3 CO_2(g) + 4 H_2O(g)[/tex]
From the equation of the reaction, the mole ratio of propane to oxygen is 1:5.
Mole of 815.74 grams of propane = [tex]\frac{ 815.74}{44.1 }[/tex]
Mole of 815.74 grams of propane = 18.49750567 moles
Mole of 1,006.29 grams of oxygen =[tex]\frac{ 1,006.29}{32 }[/tex]
Mole of 1,006.29 grams of oxygen = 31.4465625 moles
Going by the mole ratio, it appears propane is limiting while oxygen is in excess.
From the equation, 1 mole of propane produces 4 moles of water vapour. Thus, the equivalent mole of water vapour will be:
18.49750567 moles x 4 = 73.99 moles.
Using the ideal gas equation:
PV = nRT
v = (73.99 x 0.08206 x 623) ÷ 0.96
v = 3940.2
Hence, 3940.2 is the volume of water vapour that would be produced from the combustion of 815.74 grams of propane ([tex]C_3H_8[/tex]) with 1,006.29 grams of oxygen gas, under a pressure of 1.05 atm and a temperature of 350. degrees C.

If a balloon containing 0.342 moles of gas is left out in sun, the pressure is 1.54 atmospheres. If the temperature is 300 K, what is the volume of the balloon? Note R is 8.314 L kPa mol-1K-1 or 0.821 L atm mol-1K-1 .
Answer:
54.7 L
Explanation:
To find the volume, you need to use the Ideal Gas Law. The formula looks like this:
PV = nRT
In this formula,
-----> P = pressure (atm)
-----> V = volume (L)
-----> n = number of moles
-----> R = constant (0.821 L*atm/mol*K)
-----> T = temperature (K)
You need to use the second R constant because the pressure is measured in atmospheres (atm) and not kPa. Because you have the all of the necessary variables except for volume, you can substitute them into the Ideal Gas Law formula and solve.
P = 1.54 atm R = 0.821 L*atm/mol*K
V = ? L T = 300 K
n = 0.342 moles
PV = nRT
(1.54 atm)V = (0.342 moles)(0.821 L*atm/mol*K)(300 K)
(1.54 atm)V = 84.2346
V = 54.7 L

How many grams of calcium hydroxide is produced from 9.4 g of calcium chloride in this balanced
equation?
CaCl₂ + 2NaOH → 2NaCl + Ca(OH)₂
Answer:
6.27 [gr].
Explanation:
the required mass can be calculated as:
m[Ca(OH)₂]=M[Ca(OH)₂]*m[CaCl₂]/M[CaCl₂], where M - molar mass [gr/mol], m - mass [gr];
m[Ca(OH)₂]=9.4*74/111≈6.2(6) [gr].
Approximately 6.216 grams of calcium hydroxide (Ca(OH)₂₂) is produced from 9.4 grams of calcium chloride (CaCl₂) in the given balanced equation.
To determine the amount of calcium hydroxide (Ca(OH)₂) produced from 9.4 g of calcium chloride (CaCl₂) using the balanced equation, we need to use stoichiometry.
The balanced equation is:
CaCl₂ + 2NaOH --> 2NaCl + Ca(OH)₂
From the equation, we can see that 1 mole of CaCl₂ reacts with 1 mole of Ca(OH)₂. The molar mass of CaCl₂ is 111 g/mol, and the molar mass of Ca(OH)₂ is 74 g/mol.
To find the number of moles of CaCl₂, we divide the given mass by the molar mass:
Moles of CaCl₂ = 9.4 g / 111 g/mol ≈ 0.084 moles
Since the stoichiometric ratio between CaCl₂ and Ca(OH)₂ is 1:1, we know that 0.084 moles of CaCl₂ will produce 0.084 moles of Ca(OH)₂
To find the mass of Ca(OH)₂ produced, we multiply the number of moles by the molar mass:
Mass of Ca(OH)₂= 0.084 moles × 74 g/mol = 6.216 g
Therefore, approximately 6.216 grams of calcium hydroxide (Ca(OH)₂) is produced from 9.4 grams of calcium chloride (CaCl₂) in the given balanced equation.

k = Ae-36.073 = (2.2 x [tex]10^{13}[/tex] s-1)(2.156 x [tex]10^{-16}[/tex])
k = 4.743 x [tex]10^{-3}[/tex] s-1
Hence, 4.743 x [tex]10^{-3}[/tex] s-1 is the value of the rate constant.
