A homogeneous mixture is made up of multiple different substances. (You can see different parts)
Ex: Cereal in milk or ice in soda
A heterogeneous mixture is a mixture that is mixed well. ( you can’t see the different parts)
Ex: Rain or air
 
        
                    
             
        
        
        
Gravity slows it down dramatically so that is why it slows down 
        
                    
             
        
        
        
answer:
ionic bonds form between oppositely charged ions
explanation:
- an ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. 
- ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. 
- a covalent bond involves a pair of electrons being shared between atoms.
 
        
             
        
        
        
 Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O. 
Intermolecular forces exists between molecules of the same or different kinds. Water has a dipole moment hence it can interact effectively with the ions in NaCl. This leads to an ion dipole interaction that results in the dissolution of NaCl in H2O.
NaCl is a solid and water is a liquid. Since intermolecular forces is stronger in a solid than a liquid, then NaCl has stronger intermolecular forces than H2O. 
Hence, the best argument that compares the intermolecular interactions in water and NaCl is; salt is a solid and water is a liquid, so water has stronger intramolecular forces.

Answer:
160.000 años corresponde a 16.000 décadas.
Explanation:
Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:
1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?
1 década→10 años
           x    ←160.000 años
Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;
x=( )=16.000 décadas; en notación científica sería 16x10^3.
)=16.000 décadas; en notación científica sería 16x10^3.
 Respuesta: 160.000 años corresponde a 16.000 décadas.
