Answer:
C.
Explanation:
Since we are trying to find the amount of moles of oxygen, we use the balanced equation to help us out. Since there are 4 moles of Sb for every 3 moles of oxygen, we must use a conversion to let us get rid of the Sb unit and get our desired unit of moles of oxygen. Therefore, C is our best answer.

What kind of information can we read from the period system? How was it built up?
Answers
Answer: the information we can get from looking at the periodic table includes but is not limited to: the shape of electron orbitals, electron configuration, and mass of the elements. and here is what I know about how it was formed:
Explanation: as far as i know, one of the first periodic tables of the elements consisted of four elements: water, fire, earth, and air (None of these are actual elements though). One of the next ones had 33 elements, separated into four categories: games, metals, earth's, and non-metals. The final and most up-to-date version of the periodic table (or, these are the categories that mine has) has 118 elements split ugames. 7 groups (columns) and 18 periods (rows) these categories: alkali metals, alkaline earth metals, lanthanides, actinides, transition metals, post-transition metals, metabolism, reactive nonmetals, and noble gases.
First question, periods correspond to the relationship of orbitals, or likely areas in which electrons will be found, inside the outermost shell of the atom. Successive periods down the table correspond to atoms with a more electron-rich core of inner shells.
Second question, British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.

This would make 2 Carbons, 4 Hydrogens, and 4 Oxygens on each side of the equation
To know the number of atoms of an element in any compound or molecule we have to multiply the coefficients that is written in front of the molecule to the number that is written on the foot of that element. So the correct option is option B
What is Balanced equation?Balanced equation is the one in which the total number of atoms of a species on reactant side is equal to the total number of atoms on product side
The number of carbon atoms on reactant side is 2 while on the product side it is 2
The number of Hydrogen atom on reactant side is 4 while on the product side it is also 4
The number of oxygen atom on reactant side is 1 while on the product side it is 6, so to balance oxygen we multiply O₂ by 3 so the balanced equation is
C₂H₄+3O₂\(\rightarrow\)2CO₂+2H₂O
Thus the balanced equation is C₂H₄+3O₂\(\rightarrow\)2CO₂+2H₂O. Option B is correct option

Aside from the tasks it performs, perhaps the most important function of a circuit board is providing a way to integrate the electronics for a device in a compact space. A PCB allows components to be correctly connected to a power source while being safely insulated. Also, circuit boards are less expensive than other options because they can be designed with digital design tools and manufactured in high volume using factory automation.

Etching helps us to see the structure of the atoms of copper.
What is etching?The term etching refers to the process by which we expose the inner structure of copper. It is usually done electrically or by the use of an acid. The surface of the copper is removed and the inner structure of the copper is shown.
As such, when you etch copper, you can see the inner structure such as the arrangement of the atoms of copper and how they fit together.
As such looking through the etched copper would help you to appreciate that matter is composed of atoms.

Answer:
"Yes," a moving skateboard has energy.
When the skater seems to be in motion or throughout a movement, the potential energy converts itself into the kinetic form of energy, and then it becomes potential energy again.
Furthermore, somewhere after every movement, the same skateboarder was around a similar height, — in other words thus every time it is equally powerful.

The offspring resemble the parent, which makes it difficult to distinguish them from each other.
The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Answers
Answer:
The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Explanation:
If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.
The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.
Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.
As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.
