ANSWER
formed between water molecule, attraction between positive end of polar molecule and negative end
of another polar molecule
Question 15.
composition, and exchange reactions
ANSWER
Decomposition- AB=A+B exchange- AB+CD=AD+BC

base
ANSWER
combines in water
3
, Question 21.
what happens to salts when dissolved in water and what is produced?
ANSWER
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-)
ions.

inorganic molecule
ANSWER
does not contain C and H and dissociates with water
Question 25.
What is dehydration synthesis
ANSWER
taking water out (producing water) to form a new product. Uses energy
Question 26.

ANSWER
separation of two macromolecules by adding water. Releases energy
Question 27.
what are carbohydrates
ANSWER
provide energy and cell structure
