Answer:
Rayon is a synthetic fiber or man-made fiber or artificial fiber as it is prepared from the natural raw material called cellulose. ... The kind of rayon fibers which imitate the feel and texture of natural silk is therefore termed as 'artificial silk'.
Answer:
atoms
Explanation:
for sugar to dissolve in water hydaration must be equal to or greater than the lattice energy or molecular forces so when the molecular forces breaks new atoms are formed for recombination in new compound

The distinguishing characteristics of comets, meteors, and asteroids are its composition.
<h3>What are the characteristics of comets, meteors and asteroids?</h3>
Asteroids are the fragments of rock that were left over from the creation of the solar system, Meteors are the rocks that enter the atmosphere of the Earth from space while on the other hand, Comets are the remnants of the formation of the solar system that are made of dust, rocks, and ice. All these materials i.e. comets, meteors and asteroids are different from one another due to its structure and chemical composition.
So we can conclude that the distinguishing characteristics of comets, meteors, and asteroids are its composition.

Answer:
Ba(OH)₂ + 2 HBr ⇒ BaBr₂ + 2 H₂O
Explanation:
We have the products of a reaction and we have to predict the reactants. Since the products are binary salt and water, this must be a neutralization reaction. In neutralizations, acids react with bases. The acid that gives place to Br⁻ is HBr, while the base the gives place to Ba²⁺ is Ba(OH)₂. The balanced chemical equation is:
Ba(OH)₂ + 2 HBr ⇒ BaBr₂ + 2 H₂O
