Answer:
Chemical formula.
Explanation:
A chemical formula have fix proportion of atoms of elements.
Chemical formula:
A chemical formula is the way of presenting the chemical proportion of atoms of those elements, that combine to form a compound.
For example:
Water consist of two atom of hydrogen and one atom of oxygen. The atoms of both elements combine to form a compound i.e water. The atoms of both elements always combine in a fixed ratio which is 2:1 in molecule of water.
H₂O
2:1
Carbon dioxide consist of two atom of oxygen and one atom of carbon. The atoms of both elements combine to form a compound i.e carbon dioxide. The atoms of both elements always combine in a fixed ratio which is 1:2 in molecule of carbon dioxide .
CO₂
1;2
Answer: It changed in identity and properties.
Explanation:
What are you asking on this question?
It’s really any metal because metals form metallic bonds. They are the only substances which can make metallic bonds. So the answer is A
The forces between particles are called intermolecular forces. A strong intermolecular force means that the particles are tightly paced and is associated with the solid phase. Moderate intermolecular force is associated with the liquid state and little to no intermolecular force is associated with the gaseous state. Temperature has a direct effect on the state of matter in which the substance exists has. Generally speaking, a rise in tempreature changes a substance from the solid to liquid phase and from liquid to gaseus phase. The reverse is true, if the temperature lowers then the substance will go from gas to liquid and liquid to solid. It is important to not that temperature affects intermolecular forces. As the temperature increases then the individual particles become excited and gain enough energy to over the intermolecular forces and so the particles seperate from each other.
