The list of celestial bodies from smallest to largest are asteroids, moons, planets, and Stars.
What are celestial bodies?
A celestial body is an occurrence that naturally takes place in space. The terms object and body can be used interchangeably when referring to space and galaxies. Celestial bodies are firmly bound things with intricate shapes and structures that contain hundreds of smaller items.
The sun, moon, stars, and planets are examples of celestial bodies, sometimes known as heavenly bodies. The cosmos contains celestial objects, which are cosmic bodies that are visible in space and are positioned distant from the earth. We can only see the majority of the celestial groupings with a telescope.
They are usually seen at night and are invisible to the unaided eye. The size of certain celestial bodies is considerably greater than that of the planet. They are located outside of the atmosphere of the earth. There are millions of celestial bodies in the Kuiper belt.
Therefore, the list of celestial bodies, from smallest to largest are asteroids, moons, planets, and stars.

What are the 6 types of chemical reactions?
Answer:
Explanation:
Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions .
Chemical reactions can be classified into six main types based on their characteristics. The six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.
Combination reactions involve the union of two or more substances to form a more complex compound. Decomposition reactions involve the breakdown of a single compound into simpler substances.
Displacement reactions occur when an element displaces another element in a compound, resulting in the formation of a new compound and a different element. Double displacement reactions involve the exchange of ions between two compounds, leading to the formation of two new compounds.
Combustion reactions occur when a substance reacts rapidly with oxygen, producing heat and light. Understanding these different types of chemical reactions helps in predicting and understanding the behavior of substances during chemical transformations.
Therefore, the six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.

Answer:
1116.9g
Explanation:
The mass of 20 moles of Fe is 1116.9 g or 1117 g/mol.
Calculation,
The mass of one mole of [tex]Fe[/tex] = 55.85 g/mol
Mass of 20 moles of [tex]Fe[/tex] = 20×55.85 g/mol
Mass of 20 moles of [tex]Fe[/tex] = 1116.9 g ≈ 1117 g/mol

The isotopes of Madeupium (Ma) and their abundance in nature are shown below. Which is the most likely estimate of what the atomic mass is close to?
Ma-74 (74.333 - 85%)
Ma-75 (74.999 - 10%)
Ma-76 (75.700 - 5%)
A. 74 g
B. 75 g
C. 76 g
Answer:
A = 74 g
Explanation:
Given data:
Ma-74 (74.333 - 85%)
Ma-75 (74.999 - 10%)
Ma-76 (75.700 - 5%)
Atomic mass close to = ?
Solution:
1st of all we will calculate the average atomic mass.
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) + (abundance of 3rd isotope × its atomic mass) / 100
Average atomic mass = (85×74.333)+(10×74.999)+(5×75.700) /100
Average atomic mass = 6318.305 +749.99+ 378.5 / 100
Average atomic mass= 7446.795/ 100
Average atomic mass = 74.467 amu
The average atomic mass is closer to the 74 g.

Explanation:
Which sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory? higher temperature Right arrow more kinetic energy Right arrow more space between particles Right arrow higher volume higher temperature Right arrow less kinetic energy Right arrow less space between particles Right arrow higher volume higher temperature Right arrow more kinetic energy Right arrow less space between particles Right arrow lower volume higher temperature Right arrow less kinetic energy Right arrow more space between particles Right arrow lower volume
Answer:
higher temperature → more kinetic energy → more space between particles higher volume
Explanation:
Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature is directly proportional to the average kinetic energy of gas particles.
The following sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory:
higher temperature → more kinetic energy → more space between particles higher volume

The outer shell of this element was determined as illustrated here. It must be a _____.
: light metal
: heavy metal
: non metal
: noble gas
The outer shell of the given element was determined as illustrated must be a noble gas. Therefore, option D is correct.
What are noble gases?Noble gases can be described as the 6 elements that are organized in group 18 of the modern periodic table. The noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon.
Under standard temperature and pressure, noble gases exist in the gaseous form and possess low reactivity. Therefore, noble gases are also referred to as inert gas. All the noble gases exhibit stable electronic configurations in their valence shell that are completely filled. Noble gases generally exist as monoatomic.
The general outer configuration of the noble gases can be written as ns²np⁶, n is the principal quantum number. Therefore, the given electron dot diagram has eight electrons in its valence shell so it is representing a noble gas.
