Based on the data given, the correct rate law of the sample reaction is: C. [tex]R = K[A]^2[B]^1[C]^0[/tex]

What is the rate law?

Rate law can be defined as a chemical equation that is typically used to relate the initial (forward) chemical reaction rate with respect to the concentrations or pressures of the chemical reactants and constant parameters.

Mathematically, the rate law is given by this formula:

[tex]R = K[A]^x[B]^y[C]^z[/tex]

Where:

k is the rate constant.A is the concentration of reactant A.B is the concentration of reactant B.C is the concentration of reactant C.x, y, and z are the order of the reaction.

Based on the data given, the correct rate law of the sample reaction is as follows:

[tex]R = K[A]^2[B]^1[C]^0[/tex]

State one type of additional information that could be used to determine if these three species are closely related.

Answers

Answer:

Study the bone structure of limbs.

Explanation:

Study the bone structure of limbs can be used to find out the relatedness and relationship among three species because the pattern of bones structure is similar but the structure is different from one another due to different environmental conditions. This study provides important and useful information whether the three species are closely related or not. If they have similar bone structure than we can say that there are more chances that they are closely related to each other.

Which statement is correct?

Natural processes happen spontaneously when they decrease the entropy of a system because entropy increase is counteracted by the flow of enthalpy from high temperatures to low temperatures.
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.
Dissolving table salt (NaCl) in water leads to a decrease in entropy because salt particles, which are numerous individual crystals in solid form, become a homogenous solution in water.

Explanation:

Imagine dropping a glass pitcher on a hard surface. The pitcher breaks into numerous shards. If the shards were collected and dropped again, they would tend to break into smaller shards; they would not reassemble themselves into a pitcher. In the universe, there is a tendency for order to be replaced with disorder. This tendency is related to a concept called entropy. The formal definition of entropy is a measure of the degree of randomness and disorder in a system.

Genetic material (_____) is passed from cell to cell.

Answers

Answer:

DNA

Explanation:

Genetic material DNA is passed from cell to cell.

What is DNA?

DNA is Deoxyribonucleic acid. It is a polymer composed of two polynucleotide chains. These chains coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. It keeps on transferring from generation to generation. Two types of Nucleic acids are DNA and ribonucleic acid.

In DNA, 4 bases are present that are Adenine, Guanine, Cytosine and Thymine. Whereas Thymine is replaced by Uracil in case of RNA.

These bases are connected by hydrogen bonds with each other.

The configuration of the DNA molecule is highly stable, allowing it to act as a template for the replication of new DNA molecules, as well as for the production (transcription) of the related RNA (ribonucleic acid) molecule.

Therefore, Genetic material DNA is passed from cell to cell.

What is a gluon?
A. A particle that binds quarks to one another
B. A radioactive particle
C. An electrostatic force
D. A weak nuclear force

Answers

Answer:

A

Explanation:

it binds quarks together

In quantum chromodynamics the theory of the strong force, the interactions of the quarks are described in terms of eight types of massless gluon. A gluon is a particle that binds quarks to one another. The correct option is A.

What is gluon?

The gluon, so called the messenger particles is defined as the strong nuclear force which binds the subatomic particles known as quarks within the protons and neutrons of stable matter as well as within heavier short-lived particles at high energies.

It has been found that the quarks interact by emitting and absorbing gluons just as electrically charged particles interact through the emission and absorption of photons. Like quarks the gluons carry a strong charge known as colour. This means that gluons can interact between themselves through the strong force.

The gluons have no electric charge.

Thus the correct option is A.

The water is formed from oxygen gas and...hydrogen gas, I'm assuming? It would have been nice for the question to have been a bit more explicit (not blaming you, of course).

Assuming that's the case, our chemical reaction would be:

2H₂(g) + O₂(g) → 2H₂O(l).

We are told that 1 mol of a gas has a volume of 24.0 dm³ at RTP. We can use this relation to determine the number of moles of O₂ gas that reacts given its initial volume, 33.5 dm³.

33.5 dm³ O₂(g)/24.0 dm³/mol = 1.396 mol O₂(g).

Since we are not given any information about H₂(g), or any other reactant for that matter, I am assuming that the O₂(g) is the limiting reactant. According to the equation, the stoichiometric ratio between O₂ and H₂O is 1:2. That is, for every one mole of O₂ that is consumed, two moles of H₂O are formed (i.e., the number of moles of H₂O formed is double the number moles of O₂).

Since 1.396 moles of O₂ reacts, 2(1.396) = 2.792 moles of H₂O are produced. To convert moles of water to grams, we multiply the number of moles of H₂O by the molar mass of H₂O:

(2.792 moles H₂O)(18.015 g/mol) = 50.3 g H₂O.

So, approximately 50.3 grams of water are formed from 33.5 dm³ of oxygen gas at RTP.

You observe mothballs disappearing in cabinets. What do you think is the reason for this? Do all substances behave like mothballs at normal conditions? Explain by citing some examples Need lang po for science ;(

Answers

Answer: Mothballs have weak intermolecular forces.

No all substances do not behave like mothballs at normal conditions. Example: benzene , chloroform

Explanation:

Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.

A substance which undergoes sublimation is called as sublimating substance.

As mothballs is made of napthalene which has weak inter molecular forces of attraction between its molecules, it directly sublimes into gaseous state without leaving any residue and is called as a sublimating substance.

Not all substances behave like mothballs at normal conditions. Example: benzene , chloroform

Due to weak intermolecular attraction force mothballs will disappear and not every compound show this type of behavior like benzene and chloroform.

What are mothballs?

Mothballs are also known as Naphthalene balls, they are the aromatic organic compounds and they are the members of the sublimating substance family as they directly convert into gaseous state from the solid state.

In the mothballs or naphthalene balls, there is a weak attraction of force London dispersion force is present between their constitute particles, and in normal condition they show sublimation and gets disappear. Not all aromatic compounds behave like these balls as not in all compounds these types of force present, for example in benzene and chloroform strong covalent bond is present.

Hence, not all compounds behave like mothballs and they show that property due to weak attraction force.

When they were 10 years old, they always went everywhere together. All their friends knew that if they found one of them, they would find the other. Anyone who didn't know them thought that they were twins because both Kiara and Tanya had long, silky red hair and pale complexions. They were even similar in height and build. They were more like sisters than friends.But as similar as they were in appearance, they were just as different when it came to their personalities. This difference didn't affect their friendship, at least not for a long time. Kiara always got out and participated in activities and competitions. Tanya was happiest when reading a book at home. Kiara was outgoing and talkative. Tanya was quiet and shy. Kiara was popular, and people were drawn to her because of her ability to make quick friends. Tanya hardly had any friends besides Kiara.As they grew older, Kiara managed to make a large group of friends. Tanya, on the other hand, still remained shy and reserved. This difference in their personalities eventually caused a rift between the two friends. Tanya would refuse invitations to parties and movies that Kiara invited her to. She just didn't want to hang out with people she didn't know that well. Kiara couldn't understand why. She thought Tanya disliked her friends.Eventually, Kiara and Tanya both realized that they had outgrown one another. They still remained friends, but they were not as close as they once had been.
