Answer:
The purpose of molecular modeling is to provide a three-dimensional image (either physical or software-based) that allows a chemist to better see the manner in which atoms and molecules can interact. These models can be used to interpret existing observations or to predict new chemical behavior.
Explanation:
It can describe shape and how they connect while forming the electrons.
Answer:

Answer:
Percentage of silver and sulphur in the compound is 87.08% and 12.91% respectively
Explanation:
Given:
Amount of silver = 29.0 g
Amount of sulphur= 4.30 g
To find:
Percent composition of the compound=?
Solution:
Total Molecule mass = amount of silver + amount of sulphur
Total Molecule mass = 29+4.3
Total Molecule mass = 33.3g
Percentage of silver:
=>
=>
=> 87.08%
Percentage of silver:
=>
=>
=> 12.91%

Answer:
1) chemical property
2) physical property
3) chemical property
4) physical property
Explanation:
Physical properties:
Physical properties are those properties which can be measured without changing the composition of mater. We can observe the object and tell its physical properties like its texture, physical appearance, color, melting point, boiling point, odor, density etc.
Chemical properties:
Chemical properties involve chemical reaction or we can say that change is happen in mater during chemical reaction and the properties, we measured during this or as a result of this reaction is called chemical properties. Like flammability, toxicity, combustion, decomposition etc.
