Answer:
oxygen is the chemical element with the atomic number is 8 and the symbol is o its known as called oxygen.
Explanation:
Oxygen is the most third element in the universe at they standard and temperature and pressure,and oxides most elements as other compounds.
Oxygen gas is the earth atmosphere is 21%, an oxygen is the half of the earth crust in form of oxide,oxygen is liquid and solid gas.
Oxygen atoms such as proteins and acids, fats the major organic compounds, oxygen as component of the water and carbon dioxide.
Oxygen has many characteristics :- properties and molecular structure:-
this is a pressure and temperature with molecular formula referred as oxygen,simply describe a double bond and molecular orbits.
Physical properties:- oxygen is highly substance and must be combustible materials, oxygen may also from using a liquid nitrogen coolant, molecular oxygen is the associated with the process of air glow.
Stellar origin :- all of the remaining to half lives to the majority of are less then milliseconds.
Occurrence:- oxygen is the process part of the element in the earth crust, free oxygen is also occurs in the world bodies.
Analysis :- analysis to the structure of vegetation and the carbon cycle on a global scale.
Answer:
19.32 g/cm³
Explanation:
The density will remain the same no matter how many times you cut the gold. The density is g/cm³ or g/mL. Density is essentially how many grams 1 mL of a compound weighs.
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.

Answer:
By atmoic numbers........
Answer:
0.43 M
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 13 M
V1 = 10 mL
M2 = ?
V2 = 300 mL
Solve for M2 --> M2 = M1V1/V2
M2 = (13 M)(10 mL) / (300 mL) = 0.43 M
