PLEASE HELP ME ILL GIVE BRAINLIEST IF YOU EXPLAIN UR ANSWER

Answer:

0.68 mol/L

Explanation:

M=m/l

m is moles and l is liters

Since they gave us the values in the correct units, all we have to do it plug it in

M=0.34 mol/0.5 liters

M=0.68

Answer:

Chemical bonding - a mutual adhesion of atoms in an molecule and the crystal lattice.

Explanation:

Answer:

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

Answer:

Nitrogen and chlorine have similar electronegativities, making individual N-Cl bond essentially non-polar. therefore its true

Answer:

A. How hot or cold the substance is.

Explanation:

If we know the temperature of the substance

we can know how hot or cold the substance is.

And as we know temperature is the degree of hotness or coldness of a body.

Answer:

ion-dipole interaction

Explanation:

Ethanol is a polar molecule due to the presence of the polar O-H group in the molecule. This means that the molecule has a dipole moment.

The positive end of the dipole lies on hydrogen while the negative end of the dipole lies on oxygen.

When KCl is dissolved in ethanol, K^+ ions can interact with the negative end of the dipole in ethanol by ion-dipole interaction.

Answer:

T₂ = 800 K

Explanation:

Given that,

Initial temperature of the gas, T₁ = 127°C = 400 K

Initial volume, V₁ = 10 L

Final volume, V₂ = 20 L

We need to find the new temperature.

The volume of a gas is directly proportional to its Kelvin temperature.

Let T₂ is the new temperature. So,

[tex]\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K[/tex]

So, the new temperature of the gas is 800 K.

Explanation:

neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products. In a neutralization reaction, there is a combination of H+ ions and OH– ions which form water.

In chemistry, neutralization or neutralisation is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.

Answer:

Poisons are used less today than they were in the past because forensic scientists can easily detect many substances and toxins during an autopsy.

The main factor that influenced this change is advancements in forensic toxicology knowledge and technology.

good luck, i hope this helps :)

Explanation:

Today poisons are used less because forensic scientists now have much more equipment and have an easier time at identifying poisons like arsenic, which were not so easy to find in the past. The main factor influencing this change is the new technology and knowledge that was unavailable in the past.

Carbon dioxide is essential to the survival of plants and animals. Too much, however, can cause all life on Earth to die. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth's atmosphere.

Answer:

Yes

Explanation

Carbon dioxide is essential to the survival of plants and animals. Too much, however, can cause all life on Earth to die. Not only do plants and animals need to ingest carbon dioxide, but they also rely on the gas to keep them warm, as it is an essential component to Earth's atmosphere.

Answer:

B) Ni(s)

Explanation:

The question inquires which of the substances listed in the options is composed of the metallic bond. This means that we have to carefully consider the options and identify which of them is a metal. Clearly, only Ni(s) is a metal.

Metallic bonds result from the electrostatic attraction between metal cations and delocalized electrons. The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability(Khan Academy).

1. Mary and her siblings share similar hair color. Which of these cell components are most involved in determining the hair color of each sibling?

Gene, Chromosome, Nucleus

Cytoplasm, Chloroplasts,Genes

Vacuoles, Nucleus, Chromosomes

Chromosomes, Chloroplasts, Vacuoles

Answer:

Gene, Chromosome, Nucleus

Explanation:

Gene is defined in biology as "a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring" (Oxford Dictionary).

The gene is located in the chromosomes in the nucleus of cells. The sum total of the genes that an organism inherits from its parents is called the organisms' genotype and determines certain features of the organism.

The hair colour of Mary and each of her siblings depends on the genes they received from their parents.

Answer:

A nonrenewable resource is a substance that is being used up more quickly than it can replace itself. Its supply is finite. Most fossil fuels, minerals, and metal ores are nonrenewable resources. Renewable resources such as solar and wind power and water are unlimited in supply.

Answer:

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = 70.37

Explanation:

Given:

Mass of compound = 0.432 grams

Mass of oxygen = 0.128 grams

Find:

Percentage composition of oxygen

Percentage composition of fluorine

Computation:

Percentage composition of oxygen = [0.128/0.432]100

Percentage composition of oxygen = 29.69%

Percentage composition of fluorine = [(0.432 - 0.128)/0.432]100

Percentage composition of fluorine = 70.37
