Answer:
Option - It would happen faster at warmer air temperatures
Explanation:
The chemical process of converting organic matter such as plants, litter into organic soil, or organic compost called decomposition and perform by decomposers such as fungus or bacteria.
Like all other living organisms, decomposers also live in an optimal range of temperature. The major decomposers normally lie in the range of 30 to 40-degree celsius. Any type of fluctuation in this range might slow down the reaction of decomposition.
What do ionic bonds form between?
Answer:
Ionic bonds form between cations and anions.
Explanation:
Electrovalent bonds (ionic bonds) form due to the electrostatic attraction between the two oppositely charged ions in the compound. A cation is formed when a metal ion loses a valence electron. Anions are formed the opposite way: a non-metal ion gains a valence electron.

A recent decrease in carbon dioxide levels will increase plant growth on Earth.
In the past few decades, carbon dioxide levels have been rising.
In the past few decades, carbon dioxide levels have been falling.
A recent increase in carbon dioxide levels can contribute to a long-term cooling of Earth’s climate.
Answer: B - In the past few decades, Carbon dioxide levels has been rising because Rising levels of Carbon dioxide has become an immediate concern for the Environmentalists. This is because carbon dioxide is a greenhouse gas and risen levels of greenhouse gases can lead to unusual warming up of the Earth's Atmosphere.

Which orbital notation represents an atom of beryllium in
the ground state?
Answer: Beryllium is the fourth element with a total of 4 electrons. In writing the electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital. Therefore the Be electron configuration will be 1s22s2.
Explanation:
Orbital notation represents an atom of beryllium in the ground state is [tex]1s^22s^2[/tex].
Beryllium atom:Beryllium is the fourth element with a total of 4 electrons. Beryllium atoms have 4 electrons and the shell structure is 2.2. The ground state electron configuration of ground state gaseous neutral beryllium is [tex][He] 2s^2[/tex]. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. Beyond that energy, the electron is no longer bound to the nucleus of the atom and it is considered to be ionized. Electron configuration for beryllium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the remaining 2 electrons for Be go in the 2s orbital.
Therefore, the Be electron configuration will be [tex]1s^22s^2[/tex].

Write the balanced molecular equation for the acid-base reaction that occurs when aqueous solutions of hydrochloric acid (HCl) and sodium hydroxide (NaOH) are mixed.
Answer:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)
Explanation:
Sodium hydroxide (NaOH) is a strong base and hydrochloric acid (HCl) is a strong acid. That means that they are totally dissociated into ions in aqueous solution.
When a solution of NaOH is mixed with a solution of HCl, a neutralization reaction occurs, in which a salt (NaCl) and water (H₂O) are formed.
The balanced molecular equation for this reaction is:
NaOH(aq) + HCl(aq) → NaCl(aq) + H₂O(l)

Which statements correctly describe chemical reactions? Select all that apply.
Answer:
The statements that correctly describe chemical reactions are
A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.
C. If the reactants include an aluminum atom, then the products must include an aluminum atom.
E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.
Explanation:
In a chemical reaction, reactants are the elements or compounds that react to give a particular product(s). The reactants are the substances that start the chemical reaction and they are found at the left hand side of the chemical equation. While the products are found at the right hand side of the chemical equation and they are seen at the end of the reaction.
In chemical reaction, the number of atoms that starts the reaction remains the same. That is the same number of atoms is seen in the products. This follows the law of conservation of matter - which postulates that matter cannot be created or destroyed.
But in a chemical reaction, number of molecules are not conserved.
The statements that correctly describe chemical reactions are:
A. If the reactants include 5 atoms of Fe, then the products must include 5 atoms of Fe.
C. If the reactants include an aluminum atom, then the products must include an aluminum atom.
E. If there are a total of 15 atoms in the reactants, there must be a total of 15 atoms in the product.
Chemical Reaction:A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. If a physical change occurs, the physical properties of a substance will change, but its chemical identity will remain the same.
Thus, the statements that are true for a chemical reactions are A, C and E.

A truck traveled at a constant speed for 6 hours. Then, it
decreased its speed by 13 mph for the remaining 228 miles. If
the total distance was 876 miles, how long did it take to travel
the remaining 228 miles?
h
Answer:
2.4 hrs
Explanation:
The constant speed of the truck for 6 hrs can be calculated by: speed=distance/time. Speed =(876-228)/6=648/6=108m/s. So the decreased speed = (108-13)=95m/h. Now, speed =distance /time We get 95m/h = 228/t. t=228/95 hrs = 2.4 hrs PLEASE MARK ME THE BRAINLIEST!!

Energy Transfer is the Blank from one object to another object.
Answer:
Process
Explanation:
Energy transfer is the process from one object to another object
Energy transfer is the transfer of energy from one object to another object.
Energy can be defined as the ability (capacity) to do work. Hence, the only standard unit of measurement of energy is Joules (J).
Generally, there are different forms of energy and these include;
Heat (thermal) energy.Light energy.Sound energy.Wind energy.Energy transfer is a process which refers to the transfer of energy from an object or physical body to another.
According to the Law of Conservation of Energy, energy can neither be created nor destroyed but it can only be converted (transformed) from one form to another such as kinetic energy to potential energy.
For example, a jug of hot tea has heat (thermal) energy, which is added to the particles in a cold powdered milk to make the coffee hotter.

d. all of the above
help pls!!!!
Answer:
d
Explanation:
edge2020
Endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.
What do you mean by Endocrine disruptors?Endocrine disruptors may be defined as a type of extrinsic substance or mixture that significantly changes the function of the endocrine system and subsequently stimulates adverse health effects in an intact organism, its offspring, or populations.
According to the context of this question, pesticides like DDT, Atrazine, etc. plastics, and food storage materials like bisphenol A (BPA), Phthalates, Phenol, etc., and industrial by-products Polychlorinated biphenyls (PCBs) and Dioxins causes the significant and effective disruptions of the endocrine system.
Endocrine disruptors are found in numerous everyday products, including plastic bottles and containers, liners of metal food cans, detergents, flame reductions, food, and pesticides.
Therefore, endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.
