Answer:
3H2+N2-> 2NH3
Explanation:
This is the balanced chemical equation for the above reaction
★ C = 1, H = 6, O = 5
★ C = 6, H = 6, O = 1
★ the number of molecules.
Answer:
The subscripts in a chemical formula represent two things:
Explanation:
The subscripts in a chemical formula represent two things:
1. The number of atoms: The subscripts indicate the number of atoms of each element present in a compound. For example, in the chemical formula H2O, the subscript "2" indicates that there are two hydrogen atoms in each water molecule.
2. The number of molecules: The subscripts can also represent the number of molecules in a compound. However, it's important to note that this is not always the case. In most cases, the subscripts in a chemical formula specifically indicate the number of atoms rather than the number of molecules.
To clarify the examples given:
- The statement "★ the number of atoms" is correct. Subscripts in a chemical formula do represent the number of atoms.
- The statements "★ C = 1, H = 6, O = 5" and "★ C = 6, H = 6, O = 1" are not relevant to the question as they do not pertain to the role of subscripts in a chemical formula.
A particle diagram showing the composition of air would represent various gases like nitrogen, oxygen, water vapor, and carbon dioxide as spheres of different colors. The proportions between these gases would be shown by having a majority of nitrogen and oxygen spheres as they make up most of our atmosphere. The diagram may also include symbols for dust particles and particulate matter.
A particle diagram to illustrate the composition of air would visually represent the mixture of gases that comprise our atmosphere. Primarily, the atmospheric mix includes nitrogen (N₂; 78.6 percent), oxygen (O₂; 20.9 percent), water vapor (H₂O; 0.5 percent), and carbon dioxide (CO₂; 0.04 percent).
Each of these gases exist as molecules, with nitrogen and oxygen being diatomic. In other words, their molecules consist of two atoms.
In such a diagram, each type of atom would be represented as a sphere of a different color, for instance, nitrogen atoms might be blue, oxygen red, hydrogen white, and carbon grey.
The proportions would be represented by having a larger number of nitrogen and oxygen spheres compared to water vapor and carbon dioxide.
Furthermore, there might be additional entities in the diagram to represent dust particles or other environmental particulate matter suspended in the air. This allows us to get a qualitative understanding of the composition of Earth's atmosphere and mechanisms that drive gas exchange.

Answer:
Antigens are molecules capable of stimulating an immune response. Each antigen has distinct surface features, or epitopes, resulting in specific responses. Antibodies (immunoglobins) are Y-shaped proteins produced by B cells of the immune system in response to exposure to antigens.
The atomic theory develop and change as the from the Bohr's model is that how electrons occupy the space using the scientific method from the philosophy.
The John Dalton develop the Proust's work and then change the atomic philosophy of the into the scientific theory. Scientists did not believe that the electrons move in the regions not in the orbits and then they uses the mathematics and quantum numbers for the explanation.
The Bohr's model is to describe the chemical properties of an atom. The experiments demonstrated that atoms of the same element contains the different masses as the number of the neutrons can vary and called as the isotopes of the same element.
