LEARNING OBJECTIVES
? to define a chemical change
? to recognize a chemical change and distinguish it from a physical one
? to read a chemical equation
? to write chemical equations
? to balance chemical equations
? to classify chemical reactions
? to write formation and combustion reactions for given compounds.
? to recognize the limitant reactant
? to make stoichiometric calculations:
from mass to moles, from moles to mass, yield, masses needed for complete reactions (from a given quantity of a reactant)

Definition: The molar heat of neutralizing represents the quantity of heat given up when a mole of a hydronium ion interacts with a mole of hydroxyl ion in a diluted solution.

1. What is the chemical bond?
2. What is the function of the chemical bond?
3. What types of chemical bonds do you know?
