The pressure of the given moles of propane with the given volume and temperature is 1.024atm.
What is Ideal Gas Law?The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
Amount of gas n = 13molTemperature T = 288KVolume of the gas V = 300LPressure P = ?PV = nRT
P = nRT / V
P = ( 13mol × 0.08206Latm/molK × 288K ) / 300L
P = 307.23264Latm / 300L
P = 1.024atm
Therefore, the pressure of the given moles of propane with the given volume and temperature is 1.024atm.

how do atoms show both unity and diversity
Answer: As one atomic dipole nears another atom it will affect the electron density distribution, so for example if the slightly positive end of the atom is located next to another atom, it will attract the electron(s) in the other atom. A covalent bond happens when atoms share an electron between them. The other kind of bond is called ionic, and it happens when one atom gives an electron to another atom. These bonds are held together with electric forces. Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.

What are radioactive decay series?Series (or family) of natural radioactive decay is the set of elements with unstable nuclei, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.
In this case, natural radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating.

calculate the maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron
Relative atomic masses (Ar): Cl =35.5 ; Fe=56
Answer:
Here down below is the equation
Explanation:
Iron (III) chloride can be produced by the reaction shown in this equation:
2Fe +3C2 (arrow) 2FeCl3
Calculate the maximum mass of Iron (III) chloride that can be produced from 11.20 grams of iron?
Relative atomic masses: Cl= 35.5 , Fe =56
The maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.
What is mass?Mass can be defined as inertia is a quantitative measure of a fundamental feature of all stuff.
It can also be defined as weight is defined as the force exerted by an item while mass is defined as the amount of matter in an object.
The SI unit of mass is kilogram or gram.
Mass can be expressed as
Mass = Given mass of substance / Formula mass
Mass of substance = 11.20 g
Formula mass of FeCl₃ = 162.2
So, mass = 11.20 g / 162.2 g
= 0.069 grams
Thus, the maximum mass of iron(|||) chloride(FeCl₃) that can be produced from 11.20g of iron is 0.069 grams.

Which compound could serve as a reactant in a neutralization reaction?.
Answer:
In this type of neutralization reaction, the acids and bases are the reactants, since they are the materials that will react to form a new solution. The products are water and salt since they have been created following the reaction.
Explanation:
Neutralization occurs when a strong acid and a strong base come together in a chemical reaction to form water and salt.
In chemistry, acids and bases are measured on the pH scale, which ranges from 0 to 14. Pure water sits in the middle, at a neutral 7. Anything below 7 is an acid, and anything above 7 is a base. Often, solutions are either too acidic or too basic, so a reaction must take place in order to achieve neutralization.
That neutralization leads to the formation of water and salt. In chemistry, salt doesn’t necessarily just mean table salt. It is also a broader term that categorizes the compound that is created in the reaction between an acid and a base.

lead

Legionella pneumophila

The presence of lead in Flint's water is what caused the death of 12 people.
Option A.
What was in Flint's water?The Flint water crisis started in 2014 when the city of Flint, Michigan, switched its water source from Lake Huron to the Flint River as a cost-cutting measure.
The water from the Flint River was more corrosive and caused lead to leach from the pipes, contaminating the drinking water. This led to high levels of lead in the drinking water, which is a potent neurotoxin that can cause a variety of health problems, particularly in children.
The contamination also led to an outbreak of Legionnaires' disease, a severe form of pneumonia, which was linked to at least 12 deaths in the area.

H+ ion concentration of 2.5 x 10-5
Answer:
What is the hydrogen ion concentration of a solution labeled "Solution A", whose pH is 5.60?
Tutorial
In this problem we are given pH and asked to solve for the hydrogen ion concentration. Using the equation, pH = − log [H+] , we can solve for [H+] as,
− pH = log [H+] ,
[H+] = 10−pH,
by exponentiating both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of "Solution A" is,
[H+] = 10−5.6 ≈ 0.0000025 = 2.51 × 10−6 M.
We can always check our solution by computing −log (2.5 × 10−6) ≈ 5.6.

a given mass of gas occupies 500 cm³ at 25° C calculate the temperature in degree Celsius at which its volume becomes doubled at constant pressure
At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.
What is Charles's law?Charles's law states that "the volume occupied by a definite quantity of gas is directly proportional to its absolute temperature.
It is expressed as;
V₁/T₁ = V₂/T₂
Given that;
Initial volume of gas V₁ = 500cm³Initial temperature of gas T₁ = 25°CIf final volume is double of initial volume.
Final volume V₂ = 2 × 500cm³ = 1000cm³Final temperature T₂ = ?V₁/T₁ = V₂/T₂
V₁T₂ = V₂T₁
T₂ = V₂T₁ / V₁
T₂ = ( 1000cm³ × 25°C ) / 500cm³
T₂ = 25000m³°C / 500cm³
T₂ = 50°C
At constant temperature, if the volume of the gas is doubled, the pressure also doubles. The new pressure of the gas is 50°C.

A sample of lead released 2,744 J when it cooled from 90 to 19 °C. What was the
mass of the sample of lead? (The specific heat of lead is 0.129 J/g x °C)
Answer:
299.60 g
Explanation:
Use the formula q = mCΔT (q= heat, m= mass, c = specific heat for that specific substance, ΔT is change in temperature Final Temp - Initial Temp)
Released heat means it has negative sign.
q = mCΔT
-2744 = (mass) (0.129) (19-90)
mass= 299.60 g
