Answer:
C. Digestion is the answer.
Answer:
The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. ... The electrons in the energy level farthest from the nucleus are called valence electrons. Atoms in the same column (group) in the periodic table have the same number of valence electrons.
Explanation:
Answer:
1. decomposition
2. combustion
3.single replacement
4. combination
5. double replacement
Explanation:
1. one compound is split into 2 elements
2. co2 and h20 was the product of the reaction
3. cu is replaced with co
4. 2 compounds become one compound
5. ca is replaced with na and na is replaced with ca
Sucrose is insoluble in dichloromethane because dichloromethane is not a polar solvent.
Sucrose is soluble in water because the molecules of sucrose has the ability to react with the molecules of water and thereby forming hydrogen bond which enhance the dispersion of sucrose in the water.
Sugar can not react in a similar way with dichloromethane because they do not possess chemical species that can react together to form bonds. Thus, sugar is a polar substance which can not dissolve in a non-polar solvent.
