Therefore, since the density of the samples are closer to the density of pyrite (5.01 g/cm³) we conclude that the samples are more like to be pyrite.

What is pyrite?pyrite, also called iron pyrite or fool’s gold, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, “fire,” because pyrite emits sparks when struck by metal. Pyrite is called fool’s gold; to the novice its colour is deceptively similar to that of a gold nugget. Nodules of pyrite have been found in prehistoric burial mounds, which suggests their use as a means of producing fire.Wheel-lock guns, in which a spring-driven serrated wheel rotated against a piece of pyrite, were used before development of the flintlock. Pure pyrite (FeS2) contains 46.67 percent iron and 53.33 percent sulfur by weight. Its crystals display isometric symmetry. For detailed physical properties, see sulfide mineral.

How do you find partial pressure from mole fraction?

Answers

To find partial pressure from mole fraction, we have to multiply mole fraction with total pressure in the event.

How to find partial pressure with example?

Partial pressure is a result of multiplying of mole fraction and total pressure or in formula it is written as Pfraction = molefraction x Ptotal. To make it easief for you to understand, let's see the example below:

Let say we have a room with 24.2 g of He and 4.32 g of O2 at 2.611 atm pressure. In this case, before we calculate the partial pressure we have to calculate the mole fraction

24.2 g Neon x 1 mol Neon / 20.18 g Neon = 1.199 mol Neon

4.32 g Oxygen x 1 mol Oxygen / 31.998 g O2 = 0.135 mol Oxygen.

Total moles =  1.199 x 0.135 = 1.334 mol gas

Mole fraction Ne = 1.199 mol/1.334 mol = 0.899

Mole fraction O₂ = Oxygen: 0.135/1.334 = .101

Then find the partial pressure

PNe = mole fraction Ne x Ptot = 0.899 x 2.611 atm = 2.35 atm

PO2 = mole fraction O ₂ x Ptot = 0.101 x 2.611 atm = 0.264 atm

Mole ratio of reactants in reactions

The normal balanced equation of reaction between sodium (Na) and chlorine molecule (Cl2) is as follows:

Thus 2 moles of Na is required to completely react with 1 mole of [tex]Cl_2[/tex] to produce 1 mole of NaCl.

In the reaction depicted reaction 4 moles of Na and 12 moles of [tex]Cl_2[/tex] were made available for the production of NaCl. However, the mole ratio for a complete reaction is 2 moles of Na to 1 mole of NaCl.

2 moles Na = 1 mole NaCl

Answers

According to question the pressure of the gas is 4.45 atm.

What is pressure?

Pressure is a physical force exerted on a surface by an object or a liquid. It is measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). Pressure is created when a force is applied to an object, causing it to compress or expand.

The pressure of the gas can be calculated using the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

To calculate the pressure, we first need to calculate the number of moles of CO₂ gas in the container. We can do this by using the molar mass of CO₂, which is 44.01 g/mol.
n = (78.1 g CO₂) / (44.01 g/mol) = 1.77 mol
Now that we have the number of moles, we can calculate the pressure using the ideal gas law.
P = (1.77 mol)(0.0821 L·atm/K·mol)(273 K) / (48.0 L)

Answers

C. nonpolar covalent is the nature of C-Cl bond in the compound CCl4 having (Electronegativity: C-2.5, C-3,0).

A covalent bond is a chemical bond formed by the sharing of electrons between two atoms. The bond between C and Cl in CCl4 is a covalent bond. The electronegativity difference between C and Cl is small (EN C = 2.5 and EN Cl = 3.0), indicating that the bond is nonpolar covalent. In a nonpolar covalent bond, the electrons are shared equally between the atoms, and there is no separation of charge. The atoms have the same pull on the electrons, meaning that the electrons are shared equally between the atoms. In this case, the bond between C and Cl is nonpolar covalent because the electronegativity of C and Cl are similar, and the electrons are shared equally. Therefore, the bond is not polarized and there is no separation of charge. To sum up, C-Cl bond in CCl4 is not ionic and not polar covalent, it is a nonpolar covalent bond.

A gas at 110 °C exerts a pressure
of 225 torr in a sealed container.
The temperature drops to 65 °C.
What is the pressure of the gas at
the cooler temperature?

Answers

Answer:

The pressure of the gas when the temperature drops to 65°C is 133 Torr.

Explanation:

Guy-Lussacs lawThe Gay-Lussac law is a version of the ideal gas law in which the volume of the gas remains constant. A gas's pressure is exactly proportional to its temperature while its volume remains constant. The formula can be defined like this [tex]\frac{T1}{P1} = \frac{T2}{P2}[/tex].Answer BreakdownGiven informationThe gas is initially 110°C and has a pressure of 225 Torr.The temperature of the gas drops to 65°C and the question is asking us to find the pressure drop of the gas.Set up the proportionGiven the formula: [tex]\frac{T1}{P1} = \frac{T2}{P2}[/tex], T1 = 110°C  & P1 = 225 TorrT2 = 65°C & P2 = ?[tex]\frac{110C}{225 Torr} = \frac{65C}{P2}[/tex]Cross-multiply, divide, and solve110°C X P2 = 225Torr x 65°C110°CP2 = 14,625P2= 132.95 which is best rounded off to 133 Torr.
