Passage IX Q 119-123 MCAT 3

Passage IX Q 119-123 MCAT 3 Q 119 An artery is constricted at one location to 1 / 2 its normal cross-sectional area. How does the speed of blood flow past the constriction compare to the speed of blood flow in the rest of the artery? (Assume ideal fluid flow) . It is 1 / 4 as fast

Types of chemical bonds

Types of chemical bonds

Types of chemical bonds. Bond : Force that holds groups of two or more atoms together and makes the atoms function as a unit. Example: H-O-H Bond Energy : Energy required to break a bond. Ionic Bond : Attractions between oppositely charged ions.

Polyatomic Ions and Their Compounds

Polyatomic Ions and Their Compounds

Polyatomic Ions and Their Compounds. Polyatomic Ions. A polyatomic ion is an electrically charged group of two or more chemically bonded atoms that functions as a single ion. The atoms of the ion are bonded together with covalent bonds, but the group of atoms as a whole has a charge.
