Answer: Cohesion 
Explanation:
The cohesive attraction or cohesive forces is the action or property of like molecules which stick together.
It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.
Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.
Hence, the force that is present between two water molecules is cohesion.
 
 
        
                    
             
        
        
        
Answer:
CH4
Explanation:
 Combining hydrogen and carbon produces a group of organic compounds called hydrocarbons. Depending on the specific molecular formula, there can be many different types of hydrocarbons, such as the fuels propane and octane. The simplest hydrocarbon is methane, which has the chemical formula CH4.
