Answer:
3.702×10^24 atoms of Oxygen.
Total, 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.
Oxygen gas (O₂) is indeed diatomic, meaning it exists as a molecule with two oxygen atoms bonded together.
To calculate the number of oxygen atoms in 98.4g of oxygen gas (O₂), we need to use the molar mass of oxygen and the given mass.
The molar mass of oxygen (O₂) will be 32.00 g/mol.
Number of moles of oxygen gas = Mass (g) / Molar mass (g/mol)
Number of moles of oxygen gas = 98.4 g / 32.00 g/mol
≈ 3.075 moles
Since each molecule of oxygen gas (O₂) contains two oxygen atoms, the number of oxygen atoms will be twice the number of moles of oxygen gas.
Number of oxygen atoms = 2 × Number of moles of oxygen gas
Number of oxygen atoms ≈ 2 × 3.075 moles
≈ 6.15 moles
Therefore, there are approximately 6.15 moles of oxygen atoms in 98.4g of oxygen gas (O₂), which is equivalent to 6.15 × 6.022 × 10²³ (Avogadro's number) oxygen atoms.

g Identify the true statements regarding α-1,6 linkages in glycogen. At least four glucose residues separate α‑1,6 linkages. The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages. New α‑1,6 linkages can only form if the branch has a free reducing end. The reaction that forms α-1,6 linkages is catalyzed by a branching enzyme. Exactly four residues extend from these linkages.
Answer:
At least four glucose residues separate α‑1,6 linkages.
The number of sites for enzyme action on a glycogen molecule is increased through α‑1,6 linkages.
The reaction that forms α-1,6 linkages is catalyzed by a branching enzyme.
Explanation:
Glycogen is a polymer of glucose and is the primary carbohydrate storage form in animals. The polymer is composed of glucose units linked in alpha(1-4) straight chains and alpha(1-6) branches which occur on average every 8-12 straight chain glucose residues. It has a reducing and non-reducing end. The end of the molecule containing a free carbon number one on glucose is called a reducing end. The other ends are all called non-reducing ends.
During the breakdown of glycogen, glucose units are removed one at a time from the non-reducing end until a point about four glucose residues away from a branch which will require a debranching enzyme to act for further breakdown to occur. Since many such branches occur in a glycogen molecule, it makes it possible for breakdown of glycogen to occur at many points speedily.
Glycogen branching enzyme is required to make alpha (1-6) glycosidic bonds. It transfers 6 to 7 glucose units from the non-reducing end of a straight chain glycogen molecule to an interior position of the same or another glycogen molecule forming alpha (1-6) bonds.

How could a synthetic material such as Acegram affect society?
Explanation:
Synthetic fiber or synthetic fibre (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms. They are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by extruding fiber-forming materials through spinnerets, forming a fiber. These are called synthetic or artificial fibers. Synthetic fibers are created by a process known as polymerization, which involves combining monomers to make a long chain or polymer. The word polymer comes from a Greek prefix "poly" which means "many" and suffix "mer" which means "single units". (Note: each single unit of a polymer is called a monomer). There are two types of polymerization: linear polymerization and cross-linked polymerization.
Synthetic material are madeup of monomers and long chain of monomers are known as polymers. The process is known as polymerization and the synthetic material are turned as microplastic which takes a long period of time to decompose. By this way the synthetic materials are very harmful for the society.

Why is sublimation such a critical component for the water cycle in cold climates?
Answer:
Sublimation is a critical component for the water cycle in cold climates where water in the solid form or ice is prevalent because sublimation which is the transformation of a solid substance to a liquid without passing through the liquid phase including when ice transforms directly into vapors, readily takes place when the relative humidity is low and the wind is dry, which are conditions that can be found combined mainly in cold climates

54. Copper(I) sulfide is formed when copper and sulfur are
heated together. In this reaction, 127 g of copper reacts
with 41 g of sulfur. After the reaction is complete, 9 g of
sulfur remains unreacted. What is the mass of copper
sulfide formed?
SEL
Ma
Answer:
159g
Explanation:
Copper (I) sulfide is formed by the chemical reaction between copper and sulfur. Copper is a limiting reagent that results in the formation of 190.26 grams of copper(I) sulfide.
What is a limiting reagent?A limiting reagent is defined as the reactant that gets completely utilized in the reaction and affects the amount of the product formation. On the contrary, the excess reagent is present in more amounts.
Given,
Mass of copper = 127 gm
Mass of sulfur = 41 gm
Moles of copper:
n = mass ÷ molar mass
n = 127 ÷ 63.546
n = 1.99
Moles of sulfur:
n = 41 ÷ 32.065
n = 1.27
The reaction is shown as:
Cu + S → CuS
Here, 9 g of sulfur remains unreacted and hence is an excess reagent, and copper being consumed is a limiting reagent.
Here, 1 mole of copper reacts to form 1 mole of copper sulfide hence, 1.99 moles of Cu produces, 1.99 moles of copper sulfide.
Mass of CuS is calculated as:
Mass = moles × molar mass
Mass = 1.99 mol × 95.611 g/mol
= 190.26 grams
Therefore, 127 gm of copper and 41 gm of sulfur produces 190.26 grams of copper sulfide.

This reaction releases energy as heat. Explain whether the reaction is exothermic or endothermic and whether it obeys the law of conservation of energy
Answer:
Exothermic, it obeys the law of conservation of energy
Explanation:
The reaction is an exothermic change. In this kind of change, heat is liberated to the surrounding. So the surrounding becomes hotter at the end of the heat change.
In chemical reactions that involves the loss of energy as heat, they obey the law of conservation of energy.
The law of conservation of energy states that energy is neither created nor destroyed but transformed from one form to another. In such reactions as this, chemical energy is transformed into heat energy.

How do the elements in each group differ? How are they similar?
Explanation:
All the elements in one group have the same number of valence electrons. The valence electrons are those on the energy level the most distant from the nucleus. These valence electrons are those involved in bonding with other atoms to form compounds.
In the periodic table elements in the same group posses similar physical and chemical property and this is due to the similarity in the number of valence electrons found in their valence shells.
While in the periodic table as we move down a group the atomic number of the elements will continue to increase because elements in the same group are located in different periods as well.
Hence we can conclude that the difference in the elements located in a group is that they have different atomic numbers while the similarities is that the posses the same number of valence electrons.

what is Bohr's atomic model?
Answer:
The Bohr model and all of its successors describe the properties of atomic electrons in terms of a set of allowed (possible) values. Atoms absorb or emit radiation only when the electrons abruptly jump between allowed, or stationary, states. Direct experimental evidence for the existence of such discrete states was obtained (1914) by the German-born physicists James Franck and Gustav Hertz.

N2 + 3H2 Right arrow. 2NH3 What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3? Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100..
Answer:
53.4%
Explanation:
N₂ + 3H₂ → 2NH₃
Given that:
26.3 g of H₂ react with N₂ to produce 79.0 g of NH₃
Then:
The number of moles of H₂ = 26.3g of H₂ * (1 mol of H₂/ 2.02g of H₂)
= 13.05 mol of H₂
The number of moles of NH₃ = 13.05 mol of H₂ * ( 2mol of NH₃/ 3 mol of H₂)
= 8.697 mol of NH₃
The mass of NH₃ = 8.697 mol of NH₃ *( 17.04g of NH₃/ 1 mol of NH₃) = 148.1 g of NH₃
The percent yield = actual yield/ theoretical yield * 100%
The percent yield = ( 79.0 g/ 148.1 g )* 100%
The percent yield ≅ 53.4 %
Answer:
53.4
