true
Explanation:
abiotic means nonliving and biotic means living
According to the research, the correct option is Atoms can join together to form a new substance. It is the statement that correctly describes atoms.
<h3>What are atoms?</h3>
It refers to the smallest amount of a chemical element that has its own existence and is considered indivisible.
Atoms have the properties of the chemical element they compose and, in turn, can combine with each other to form chemical bonds, and to constitute different chemical compounds and substances that make up the organs and organ systems in living beings, the materials generated in industry, and all the matter that makes up the universe.
Therefore, we can conclude that according to the research, the correct option is Atoms can join together to form a new substance. It is the statement that correctly describes atoms.

The coefficients that will balance the tarnishing reaction equation are: 2, 1, 1,1
What is a chemical equation
Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.
The reactants are located on the left side while the products are located on the right side.
Reactants —> Products
The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.
Thus, we can obtain the coefficients that will balance the tarnishing reaction equation by simply balancing the equation:
How to balance the equation
Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
There are 2 atoms of Ag on the right side and 1 atom on the left side. It can be balanced by writing 2 before Ag as shown below:
2Ag(s) + H₂S(g) → Ag₂S(s) + H₂(g)
Thus, the equation is balanced.
The coefficients are: 2, 1, 1, 1 :)
<h2>
Simple diffusion is defined as the movement of: A molecules from areas of higher concentration to areas of lower concentration.</h2>
Explanation:
Diffusion
It is the movement of substances from the region of higher concentration to lower concentration .
This diffusion is shown almost negligible by solids , a little by liquids and maximum by gases .
The factors on which diffusion depends :
- Inter-molecular force between particles : It is inversely proportional to diffusion .That is : more is the force , lesser the diffusion rate
- Inter-molecular space between particles : More is the space , more is the diffusion or vice versa .
- Density of substance :More is the density , less is the diffusion or vice versa .
Applications of diffusion
It helps in the movement of substance in and out from the cell and its components .
It helps in spreading the fragrance when sprayed with some perfume etc .
It helps in dissolving substance in any medium
Etc
Here N H 4 O H { NH }_{ 4 }OH NH4OH is not a strong electrolyte because it doesn't dissociates completely.
