is chcl3 polar or nonpolar

Answers

Answer 1

[tex]CHCl_{3}[/tex] is polar

Polar - A polar covalent link is created when atoms with different electronegativities share electrons to form a covalent bond. Polar bonding have a high melting point, low vapor pressure, high surface tension, and low boiling point. Polar chemicals interact with one another. On opposite ends of these molecules, there are positive and negative charges. They have electrical charge as a result. Examples include alcohol and Sulphur.

Chloroform has a tetrahedral molecular geometry, with the carbon atom at the center and the three chlorine atoms and one hydrogen atom located at the corners of the tetrahedron. The molecule has a dipole moment due to the unequal sharing of electrons between the carbon and chlorine atoms.

The chlorine atoms are more electronegative than the carbon atom, causing the electrons to be pulled closer to the chlorine atoms, which creates a partial negative charge. This results in the carbon atom having a partial positive charge. The polarity of the molecule makes it useful as a solvent for polar and nonpolar compounds.

according to the information in the graphs and the table how was species diversity in the aquatic ecosystems affected by the increased water temperature

Answers

Species diversity in aquatic ecosystems is significantly affected by the increased water temperature. This is because warm water holds less dissolved oxygen than cool water, and may not contain enough dissolved oxygen for the survival of different species of aquatic life.

What is an ecosystem?

An ecosystem may be defined as a type of place or an area where members of different species live together and interact with one another for the purpose of food, shelter, space, mating partner, and other resources.

The solubility of oxygen and other gases will decrease as temperature increases. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.

Some compounds are also more toxic to aquatic life at higher temperatures. So, warm stream water is can affect the aquatic life in the stream.

which element has the lowest 1st ionization energy? A. As B.P C. N. D.Bi E.Sb

Answers

The element has the lowest 1st ionization energy is N ( nitrogen). Th correct answer is C.

First, the energy needed to remove one electron from a neutral atom in order to create a positive ion is referred to as the ionization energy or ionization potential. It is described as the energy difference between a neutral atom's and a positive ion's ground states.

The ease with which an atom can lose electrons and produce positive ions makes the initial ionization energy a crucial chemical feature of an element.

Higher first ionization energy suggest that removing an electron from an atom is more challenging, whereas lower first ionization energies suggest that removing an electron from an atom is simpler.

For each element, the first ionization energy varies, and it can be used to determine an element's electron configuration, electron affinity, reactivity, and chemical behavior.

what is the average distance between oxygen molecules at stp?

What is Atomic Radius ?

Atomic radius is the distance between the nucleus of an atom and its valence electrons. It is typically measured in picometers (pm) or angstroms (Å) and is used to describe the size of an atom. The atomic radius can vary depending on the element and its electronic configuration, and can also vary in different states (ionization states, for example). The trend for atomic radius generally increases down a group on the periodic table and decreases across a period from left to right.

where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature.

The volume of one mole of gas at STP is 22.4 L according to the molar volume of a gas.

For oxygen gas (O2), the molar mass is approximately 32 g/mol. Therefore, one mole of oxygen gas contains 6.02 × 10^23 oxygen molecules.

Using the ideal gas law, we can solve for the volume of one oxygen molecule:

V = (RT/P) * (1/n)

V = (0.0821 L atm/mol K * 273 K / 1 atm) * (1 / 6.02 × 10^23 molecules)

V ≈ 4.0 × 10^-23 L

The volume of one oxygen molecule is incredibly small, so the average distance between oxygen molecules at STP is very close to zero. However, we can estimate the average distance by assuming that the molecules are arranged in a regular pattern, such as a simple cubic lattice.

In a simple cubic lattice, each oxygen molecule is surrounded by six nearest neighbors. The distance between adjacent molecules is equal to the cube root of the volume of one molecule and its six neighbors:

d = (V_molecules/6)^(1/3)

d = (4.0 × 10^-23 L / 6)^(1/3)

d ≈ 1.9 × 10^-8 cm

Therefore, the average distance between oxygen molecules at STP is approximately 1.9 × 10^-8 cm.

The volume of a balloon was 4.21 L when the temperature was 25.0 °C, what will the volume of the balloon be when the temperature is

Answers

To solve this problem, we need to use the ideal gas law, which relates the pressure (P), volume (V), number of moles (n), and temperature (T) of a gas:

PV = nRT

where R is the universal gas constant.

Assuming that the number of moles and the pressure of the gas remain constant, we can write:

V1/T1 = V2/T2

where V1 is the initial volume of the balloon, T1 is the initial temperature, V2 is the final volume of the balloon, and T2 is the final temperature.

Plugging in the given values:

V1 = 4.21 L
T1 = 25.0 °C + 273.15 = 298.15 K (converting to Kelvin)
T2 = 50.0 °C + 273.15 = 323.15 K (converting to Kelvin)

We can solve for V2:

V2 = V1 x T2/T1
V2 = 4.21 L x (323.15 K / 298.15 K)
V2 = 4.21 L x 1.084
V2 = 4.56 L (rounded to two decimal places)

Therefore, the volume of the balloon will be 4.56 L when the temperature is 50.0°C.

Answers

Avogadro's law states that 2.2075 moles must be added to the container in order to raise the pressure to 325 kPa.

What is meant by Avogadro's law?

The general number of atoms or molecules has a direct relationship to the volume occupied by a gas under constant temperature and pressure, according to Avogadro's law, a gas law.

Given that it links temperature, pressure, volume, and substance amount, it is closely related to the ideal gas equation.

V ∝ n,

The straight line graph of volume versus moles is a straight line passing through the origin which implies that zero moles of gas occupy zero volume.

As 1 atm = 101.325 kPa

325 kPa = 325/101.325 = 3.2075 atm, as at STP 1 atm =22.4 liter.

Applying Avogadro's law,

n₂ = 71.848 × 1/22.4 = 3.2075 moles .

To estimate moles to be added, we get

How does the subject of this poem relate to Native American Traditions?This is the song of the Friend, Made by the Medicine Man In the young dusk of the spring, Moonless and tender, At the hour when the balm-giving herbs Begin to be musky and sweet along the creek borders, When the smell of the sage is sharp in the trails of the cattle And the ants run busily still Up the poles of the pine trees; The shuffle and beat of his feet We heard in the dust by his doorway. Out and aside from the hut The pound of his feet and the roll of the ram's-horn rattle Was more loud than the purr of the creek Or the wings of the night hawk, And the drone of his singing sweet And the night desirous. All night he sang till the young, thin moon came out, And about the wolf hour of the morning The earth by his hut was beaten to dust by his dancing, And the eyes of the Medicine Man Were pale as the sloughs before sun-dawn, And the shadow of all his songs Lay under them and in the cheek hollows Like ash on the hearthstone; And his voice was bitter and thick As the dust stirred up by his dancing. And still in my heart I hear the throb of his singing When I go by the sweet-smelling trails In the moonless evenings of April. My pulse is full of the whisper and beat, Over-full and aching with song, When the smell of the campfire comes out by the creeks And the nights are young and desirous.Answers:A: The politics of cultures and wars are viewed as more important than the natural world.B: The simplicity of life among the natural world is portrayed in a positive light.C: The poem favors the success of civilization in America to the trapping of nature.D: The poem focuses of the strife Native Americans faced by European colonization. Lake Erie is prone to remarkable seiches-standing waves that slosh water back and forth in the lake basin from the west end at Toledo to the east end at Buffalo. The figure shows smoothed data for the displacement from normal water levels along the lake at the high point of one particular seiche. 3 hours later the water was at normal levels throughout the basin; 6 hours later the water was high in Toledo and low in Buffalo.the Wavelength is 800 kmWhat is the frequency and wave speed? The local zoo has a total of 238 birds and 34 species of birds. If the zoo has the same number of each species, how many birds of each species does the zoo have?
