1st law of thermodynamics - Energy cannot be created or destroyed 2nd law of thermodynamics - Every energy transfer or transformation increases the entropy of the universe. Acids - pH less than 7 Adhesion - attraction between molecules of different substances all atoms want... - to be neutral (P=e-) and to have a full valence shell (8) Anabolic - complex molecules made from simple atomic mass - Number of protons + neutrons atomic number - the number of protons in the nucleus of an atom ...

Question 1 3 / 3 pts Question 6 3 / 3 pts Question 7 3 / 3 pts Question 8 3 / 3 pts Cytosine Both A and B CYTOSINE Water is considered a polar solvent due to attractive forces known as hydrogen bonds. A hydrogen bond is . A bond that is stronger than a covalent bond An attractive force between molecules where partially positive hydrogen atoms are attracted to partially negative atoms of F, O, or N. The polar O–H bond in water An ionic bond between H and another atom A covalen...
