Answer:
This question lacks options, however, it can be answered based in general understanding. The answer is:
The carbon is released into the atmosphere and soil during decomposition
Explanation:
Carbon is an important element that makes up the biomass of living organisms. Organisms like plants as described in this question, store carbon as sugars, which they synthesized during photosynthesis. However, when they decompose/decay, they lose this carbon content.
Decomposition is the process carried out by microbes such as fungi, bacteria etc involving the breaking down of an organic molecule into inorganic ones. Hence, when leaves of a plant die, they undergo decomposition i.e. the carbon content in their leaves present as sugar (organic molecules) is broken down to release the carbon in form of carbon dioxide, into the atmosphere, soil etc. Hence, the carbon that is stored in leaves are RELEASED when they decay causing them to lose mass.

How many moles of manganese in 4.07 x 1024 atoms of manganese?
Answer:
6.76 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{4.07 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 6.760797...[/tex]
We have the final answer as
6.76 molesHope this helps you
How many atoms are there in 32.45 grams of Magnesium?
Answer:
8.13 ×10²³ atoms
Explanation:
Given data:
Mass of magnesium = 32.45 g
Number of atoms = ?
Solution:
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 32.45 g/ 24 g/mol
Number of moles = 1.35 mol
Number of atoms:
1 mole contain 6.022×10²³ atoms
1.35 mol × 6.022×10²³ atoms/ 1mol
8.13 ×10²³ atoms
Calculate the wavelength of radiation with a frequency of 4.9 ×1014 per second.
Answer in units of meters.
The wavelength-λ = 6.12 x 10⁻⁷ m
Further explanationRadiation energy is absorbed by photons
The energy in one photon can be formulated as
[tex]\large{\boxed{\bold{E\:=\:h\:.\:f}}}[/tex]
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸ m/s
λ = wavelength
The wavelength of radiation with a frequency of 4.9 ×10¹⁴/s :

A. Compound, allotrope, double bond, one element
B. Molecule, compound, single bond, allotrope
C. Simple structure, diatomic, double bond, molecule
D. Giant structure, single bond, compound, one element
Simple structure, diatomic, double bond, molecule. Hence, option C is correct.
What is a compound?A pure substance made up of two or more different elements combined chemically in a fixed ratio is called a compound.
[tex]O_2[/tex] is a covalent molecule because each oxygen atom needs two valence electrons to complete its octet. To meet this need each oxygen atom shares two of its electrons with the other oxygen forming a strong oxygen-oxygen double-shared covalent bond.
Hence, option C is correct.

Answer:
Explanation:
During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient.

An ice skater moves back and forth on an ice rink. She speeds up on the straight portion of the rink. She slows down near each end of the rink and then turns around. Which claim supported by evidence?
The options are;
A) The skater experiences acceleration both while skating in a straight line and while making her turn.
B) Because the skater does not change her direction or speed, she does not experience acceleration.
C) The skater only experiences acceleration when she is turning.
D) The skater only experiences acceleration while skating in a straight line.
Answer:
A: The skater experiences acceleration both while skating in a straight line and while making her turn
Explanation:
We are told that She speeds up on the straight portion of the rink. This means that she experienced an acceleration since the speed was not constant but gradually increasing.
Also, we are told that She slows down near each end of the rink and then turns around. This means that she reduced speed before turning and it means there was also an acceleration as well when making the turn.
Thus, she experience acceleration both in the straight line and when making turn.
Option A is correct

The atomic model gives a detailed understanding of the atoms and the sub-atomic particles. The models were given in order by Dalton, Thomson, Rutherford, Bohr, and Schrödinger. Thus, option C is correct.
What is the atomic model?
The atomic model is the representation of the atom of the element along with the sub-atomic particles. The first model was given by Dalton, which stated that matter is composed of atoms.
Later Thomson discovered the presence of the electron present in the sea of the positive charges. In addition, Rutherford gave the presence of the positive nucleus in the middle of the atom.
Bohr's model gave the presence of the electron in the orbit of the atom around the nucleus. At last, the current atomic model was given by Schrödinger and is known as the electron cloud model.
Therefore, option C. Gina should Switch 4 (Schrödinger' model) with model 5 ( Bohr 's model).

Answer:
When we kick the ball, the force we apply to it causes it to accelerate from a speed of 0 to a speed of dozens of kilometers per hour. When the ball is released from the foot, it begins to decelerate (negative acceleration) due to the force of friction that is exerted upon it (as we observed in the previous example).

What could cause the Earth's crust to become a liquid?
Answer:
Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust. (Basalts are a sima rocks.) Oceanic crust is dense, almost 3 grams per cubic centimeter (1.7 ounces per cubic inch).
Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other. As magma that wells up from these rifts in Earth’s surface cools, it becomes young oceanic crust. The age and density of oceanic crust increases with distance from mid-ocean ridges.
Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.
At convergent plate boundaries between continental and oceanic lithosphere, the dense oceanic lithosphere (including the crust) always subducts beneath the continental. In the northwestern United States, for example, the oceanic Juan de Fuca plate subducts beneath the continental North American plate. At convergent boundaries between two plates carrying oceanic lithosphere, the denser (usually the larger and deeper ocean basin) subducts. In the Japan Trench, the dense Pacific plate subducts beneath the less-dense Okhotsk plate.
