Answer:
A
Explanation:
it binds quarks together
In quantum chromodynamics the theory of the strong force, the interactions of the quarks are described in terms of eight types of massless gluon. A gluon is a particle that binds quarks to one another. The correct option is A.
What is gluon?The gluon, so called the messenger particles is defined as the strong nuclear force which binds the subatomic particles known as quarks within the protons and neutrons of stable matter as well as within heavier short-lived particles at high energies.
It has been found that the quarks interact by emitting and absorbing gluons just as electrically charged particles interact through the emission and absorption of photons. Like quarks the gluons carry a strong charge known as colour. This means that gluons can interact between themselves through the strong force.
The gluons have no electric charge.
Thus the correct option is A.

1. The pH of a solution made by combining 150.0 mL of 0.10 M KOH with 50.0 mL of 0.20 M HBr is closest to which of the following?
Answer:
12
Explanation:
The pH of the solution prepared has been 1.25.
The pH of the solution resulting from the mixing of the two solutions can be given by:
Hydrogen ion concentration = [tex]\rm \dfrac{M_1V_1\;-\;M_2V_2}{V_1\;+\;V_2}[/tex]
Where, M1 and M2 have been the molarity of the solution and V1 and V2 have been the volume of the solutions.
For the given resulted solution:
Hydrogen ion concentration = [tex]\rm \dfrac{0.1\;\times\;0.15L\;-\;0.2\;\times\;0.05L}{0.15\;+\;0.05\;L}[/tex]
Hydrogen ion concentration = 0.055 M
pH can be defined as the negative logarithm of hydrogen ion concentration.
pH = - log (Hydrogen ion concentration)
pH = -log (0.055)
pH = 1.25
The pH of the solution prepared has been 1.25.

An unknown amount of Al203 decomposed producing 215 g of solid aluminum. 2Al2O3=4Al+3O2 How many grams of oxygen gas should be produced
Answer:
191.11 grams of oxygen gas should be produced.
Explanation:
The balanced reaction is:
2 Al₂O₃ → 4 Al + 3 O₂
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
Al₂O₃: 2 molesAl: 4 molesO₂: 3 molesBeing the molar mass of each compound:
Al₂O₃: 102 g/moleAl: 27 g/moleO₂: 32 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
Al₂O₃: 2 moles* 102 g/mole= 204 gramsAl: 4 moles* 27 g/mole= 108 gramsO₂: 3 moles* 32 g/mole= 96 gramsThen you can apply the following rule of three: if by stoichiometry 108 grams of aluminum are produced along with 96 grams of oxygen, 215 grams of aluminum are produced along with how much mass of oxygen?
[tex]mass of oxygen=\frac{215 grams of aluminum*96 grams of oxygen}{108grams of aluminum}[/tex]
mass of oxygen= 191.11 grams
191.11 grams of oxygen gas should be produced.

what is the mass of 0.083 moles of iron to the nearest tenth
Answer:
The answer is 0.01790670606142. We assume you are converting between moles Iron and gram.
Explanation:
The mass of 0.083 moles of iron to the nearest tenth is 0.4635135 grams.
What is mass?Mass is defined as the amount of substance contained in a particle or object as a dimensionless quantity. An object's mass is the entire amount of matter it contains. A scalar quantity, it. By using beam balance, it is measured. The object's mass is constant everywhere it is. The inertia of an object allows us to calculate its mass.
One carbon-12 atom weighs exactly 12 atomic mass units, which equals its atomic mass. One mole of carbon-12 atoms weighs exactly 12 grams; this is known as the molecular mass of carbon-12.
Molar mass of iron is 55.847 moles
Molar mass = mass/mole
Mass = molar mass x mole
Mass = 55.845 x 0.083
Mass = 0.4635135 grams.
Thus, the mass of 0.083 moles of iron to the nearest tenth is 0.4635135 grams.

Two reactant particles collide with proper orientation. The collision will be effective if the particles have
(A) sufficient potential energy
(B) high activation energy
(C) high ionization energy
(D) sufficient kinetic energy
And explain why, and answer in brainly
The collision will be effective if the particles have sufficient kinetic energy (Option D).
Kinetic energy is motion energy, conversely to potential energy.Kinetic energy is required to produce the collision between particles.The more kinetic energy the particles have, then the more collision will occur, thereby it increases the rate of a chemical reaction.In conclusion, the collision will be effective if the particles have sufficient kinetic energy (Option D).

Determine the freezing point depression of 2 kg of water when 2 mol salt is added to it. The kf of water is 1.86 degrees C/M. Show all your work.
Answer: The freezing point depression is [tex]1.86^0C[/tex]
Explanation:
Depression in freezing point is given by:
[tex]\Delta T_f=K_f\times m[/tex]
[tex]\Delta T_f[/tex] = Depression in freezing point
[tex]K_f[/tex] = freezing point constant = [tex]1.86^0C/m[/tex]
m= molality = [tex]\frac{\text {moles of solute}}{\text {mass of solvent in kg}}=\frac{2mol}{2kg}=1m[/tex]
[tex]\Delta T_f=1.86mol/kg^0C\times 1m[/tex]
[tex]\Delta T_f=1.86^0C[/tex]
Thus freezing point depression is [tex]1.86^0C[/tex]

Lithium arsenate (Li3AsO4) and iron nitrate (Fe(NO3)3) are dissolved in water. What precipitate would you expect to form? what is the name and formula?
Answer:
CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻The chemical formula of the precipitate is Fe(OH)₃Explanation:
Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociate in water. Carbonate ions is a weak base and combine with water to form hydroxide ions (OH⁻), CO₃²⁻ + H₂O <----------------> HCO₃⁻ + OH⁻ Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.
