Answer:

3.97 x 10^-19 J

Explanation:

The energy E of a photon is given by:

       E = hf where h = Planck's constant = 4.14 × 10−15 eV · s and f = frequency

In this case, f = 6×10^14s−1, hence, the energy E of one photon of the light would be;

E = 4.14 × 10−15 eV · s x 6×10^14s−1

               =  2.484 eV

Note that:

1 eV = 1.60 × 10−19 J

Hence,

2.484 eV = 2.484 x 1.60 × 10−19 J

              = 3.97 x 10^-19 J

False. A prochiral center does not describe an sp_3 hybridized atom that can become a chirality center by changing one of its attached groups.

A prochiral center is an atom that possesses chirality, meaning it can become a chirality center by changing its stereochemistry. However, the statement in question is incorrect because a prochiral center does not require changing one of its attached groups to become a chirality center.

In contrast, a prochiral center is a type of stereocenter that exhibits chirality due to the presence of two different groups attached to it. It becomes a chirality center when one of the groups is replaced by another group, resulting in the formation of two distinct stereoisomers.

An example of a prochiral center is a carbon atom with three different groups attached to it. Upon substitution of one of the groups, the prochiral center becomes a chirality center, giving rise to enantiomers.

Therefore, the statement that a prochiral center can become a chirality center by changing one of its attached groups is false.

Physical change

Explanation:

The only change is in the shape, or length in this case, of the object. So its chemical makeup is still the same, it's still grass.

Mowing the lawn is considered a physical change. A physical change is a change in the physical properties of a substance or material without altering its chemical composition.

A physical change is a transformation that alters the physical properties of a substance, such as size, shape, or phase, without changing its chemical composition. In the case of mowing the lawn, the grass is physically cut into smaller pieces, but the individual grass blades themselves remain chemically unchanged.

When you run a lawnmower over a lawn, the sharp blades of the mower cut through the grass, trimming it to a desired height. This action changes the appearance and size of the grass, but it does not alter the identity or chemical composition of the grass. The grass blades are still composed of the same materials, such as cellulose and other organic compounds.

When you mow the lawn, you are cutting the grass blades into smaller pieces, but the grass itself remains the same chemically. The process of mowing only affects the physical appearance and size of the grass, not its fundamental composition.

Therefore, mowing the lawn is considered a physical change.

He argued that Earth rotates on its axis

Explanation:

The hypothesis that the Sun is at the center of the universe and the Earth, the other planets and other heavenly bodies are revolving around the Sun was first proposed by Aristarchus of Samos who also believed that the motion of the stars where actually due to the rotation of the Earth about its axis

However, the propositions where rejected at the time because it was contrary to perception and senses such that a revolving Earth has to have a moving "great wind" in the air around us

Aristarchus's explanation of the movement of objects in the sky was different from that of other scientists because he argued that Earth rotates on its axis.

The solar system was deeply studied by the early astronomers. Each of them offered an explanation for the movement of objects in the sky. Some of these postulations were inconsistent with scientific evidence.

However, Aristarchus postulated that the sun is at the center of the solar system and that the earth and other planets move round the sun in orbits.

Hence, he suggested that the sun and not the earth was at the center of the solar system.

Balanced redox reaction in acidic solution: 2MnO₄⁻ + 16H+ 10C₂O₄⁻² → 2Mn² + 10CO₂ + 8H₂O.

The reaction involves oxidation of C₂O₄⁻² to CO₂ and reduction of MnO₄⁻ to Mn².

The given redox reaction is:

MnO₄⁻ + C₂O₄⁻² → Mn² + CO₂

To balance this equation in acidic solution, we need to follow the steps below:

Step 1: Write the half-reactions for the oxidation and reduction processes.

MnO₄⁻ → Mn² + (Reduction)

C₂O₄⁻² → CO₂ (Oxidation)

Step 2: Balance the atoms in each half-reaction.

MnO₄⁻ → Mn₂+ 4H (Reduction)

C₂O₄⁻² → 2CO₂ + 2e⁻ (Oxidation)

Step 3: Balance the electrons in each half-reaction by multiplying them by appropriate factors.

MnO₄⁻ + 8H + 5e⁻ → Mn² + 4H₂O (Reduction x 5)

C₂O₄⁻² → 2CO₂ + 2e⁻ (Oxidation)

Step 4: Multiply each half-reaction by a factor to make the electrons lost equal to the electrons gained.

2MnO₄⁻ + 16H + 10e⁻→ 2Mn² + 8H₂O (Reduction x 2)

5C₂O₄⁻²→ 10CO₂ + 10e⁻ (Oxidation x 5)

Step 5: Add the half-reactions and cancel out common terms to obtain the balanced redox reaction.

2MnO₄⁻ + 16H + 10C₂O₄⁻²→ 2Mn² + 10CO₂ + 8H₂O

Therefore, the balanced redox reaction in acidic solution is:

2MnO₄⁻ + 16H + 10C₂O₄⁻² → 2Mn²+ 10CO₂ + 8H₂O

Explanation:

Denise most likely wrote in her lab report that the data did not support the hypothesis because the amount of dissolved oxygen increased as water temperature increased.

This is because the hypothesis typically states that as water temperature increases, the amount of dissolved oxygen should decrease due to decreased solubility.

However, the data collected shows the opposite, suggesting that there may be other factors at play affecting the oxygen levels in the water. It is important for scientists to report their findings accurately, even if it goes against their initial hypothesis.

This allows for further research and investigation to determine the true cause of the observed phenomenon. In this case, Denise's report may prompt further investigation into what is causing the increase in dissolved oxygen levels with increasing water temperature.

When a compound in a reaction gains an electron, that compound has been reduced.

When a compound gains an electron in a chemical reaction, it is said to be reduced. In a chemical reaction, the substance that donates an electron is said to be oxidized while the one that accepts it is reduced. About half of all chemical reactions that occur in the body involve the exchange of electrons, and these reactions are known as redox reactions.

The transfer of electrons is vital to the functioning of many biological processes, such as cellular respiration, photosynthesis, and the metabolism of drugs and toxins.

The term "reduced" is used because the compound that accepts an electron has a lower oxidation state, meaning it has gained electrons and has been reduced in terms of its overall charge.

The illustration of Thomson's atom represents a neutral atom. In this case, the total amount of positive charge and the total amount of negative charge must be equal. This means that there are equal numbers of protons and electrons in the atom. This is what makes the atom neutral.

A neutral atom is an atom that has no electrical charge. An atom is neutral because it has the same amount of positively charged protons and negatively charged electrons. The nucleus of an atom contains protons, which are positively charged particles. Electrons, which are negatively charged particles, are located in the atom's electron cloud around the nucleus.

Electrons, protons, and neutrons are the three components of atoms. Electrons are negatively charged, protons are positively charged, and neutrons have no charge. Electrons are found outside the nucleus of the atom and are continually moving at high speeds.

In summary, if the illustration of Thomson's atom represents a neutral atom, then the total amount of positive charge and the total amount of negative charge must be equal. This means that there are equal numbers of protons and electrons in the atom. This is what makes the atom neutral.

Answer:

Gravity.

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

The attraction between all objects that have matter is generally referred to as gravity.

Generally, this force of attraction (gravity) attracts an object (body) towards another having mass, or towards the center of a planetary body such as earth.

If the [H3O+] (hydronium ion concentration) in an aqueous solution is 8.1 x 10^-12 M, the solution is considered basic.

Here's a step-by-step explanation:
1. Recall that the ion product constant of water (Kw) is 1.0 x 10^-14 at 25°C.

2. The relationship between hydronium ion concentration [H3O+], hydroxide ion concentration [OH-], and Kw is given by the equation: [H3O+] [OH-] = Kw

3. Given the [H3O+] = 8.1 x 10^-12 M, you can calculate the [OH-] by rearranging the equation: [OH-] = Kw / [H3O+] = (1.0 x 10^-14) / (8.1 x 10^-12) = 1.23 x 10^-3 M.

4. Compare the [H3O+] and [OH-] concentrations:
  - If [H3O+] > [OH-], the solution is acidic.
  - If [H3O+] < [OH-], the solution is basic.
  - If [H3O+] = [OH-], the solution is neutral.

5. Since [H3O+] (8.1 x 10^-12 M) is less than [OH-] (1.23 x 10^-3 M), the solution is basic.
