Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

[tex]PV=nRT[/tex]

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

[tex]751.2mmHg (torr) =0.988atm[/tex]

Now plug everything in

[tex](0.988)(26)=(0.97)(0.0821)T\\T=322.56K[/tex]

Answer:

3.82 × 10 ^-23 g

Explanation:

6.02 x 10^23atoms = 1 mole of sodium

1 atom = 1/(6.02 x 10^23) mole

mass = mole × molar mass

= 1/(6.02 x 10^23) × 23

= 3.82 × 10 ^-23 g

Answer:

The hydroxide ion concentration in an aqueous solution, [OH-], in mol L-1, can be calculated if the pOH of the solution is known.

pOH is defined as the negative logarithm (to base 10) of the hydroxide ion concentration in mol L-1 pOH = -log10[OH-]

Explanation:

The term “INTERmolecular forces” is used to describe the forces of attraction between atoms, molecules, and ions when they are placed close to each other.

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.

In a liquid, intermolecular attractive forces hold the molecules in contact, although they still have sufficient KE to move past each other. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behaviour of liquids and solids and are electrostatic in nature.

Answer:

2.00

Explanation:

From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.

Let the rate of effusion of Helium be R1

Let the rate of effusion of Methane be R2

Let the molecular mass of Helium be M1

Let the molecular mass of Methane be M2

Hence;

R1/R2 = √M2/M1

R1/R2 = √16.0294/4.0026

R1/R2 = 2.00

Answer:

Explanation:

When a comet enters the solar system it curves towards the Sun due to the Sun's gravitational pull. Every celestial object in the universe has a gravitational pull whose force is dependent on the object's mass. The larger the object is the more gravitational pull it will have. The Sun is the largest object in our Solar system and therefore has the most gravitational pull. This is why the comet curves toward the Sun, but the opposite does not happen because the comet's gravitational pull is not strong enough to pull the Sun.                  

The chemical formula of CO, Fe₂O₃, and C₂H₄ contain atoms of two different elements. Therefore, option (D) is correct.

A chemical formula provides information about the chemical proportions of atoms of each element that are present in a molecule or chemical compound. The chemical formula can be represented by using chemical symbols of elements, numbers (subscripts), and other symbols, such as commas, dashes, brackets, and plus (+) and minus (−) signs.

A chemical formula of a compound has no words but can be written in certain simple chemical structures. Chemical formulae can be more limited in power than chemical names and structural formulae. There are two kinds of chemical formulas in which one empirical formula and another molecular formula.

In the chemical formula of carbon monoxide (CO) has carbon and oxygen two different elements. In the chemical formula of iron oxide (Fe₂O₃)  iron and oxygen are two different elements. In the chemical formula of ethane (C₂H₄ ) has carbon and hydrogen two different elements.

Explanation:

To convert the mass to moles, divide the mass by the atomic weight of the element or compound.

To convert back to mass from the moles, multiply the moles by the atomic weight of the element or compound

Answer: The distribution of natural resources depends upon many physical factors like land, climate and altitude. The distribution of resources is unequal because these factors differ from place to place on this earth.

Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.

The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.

The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.

Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.

Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

Answer:

The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.
