Concept 2.4 Chemical reactions make and chemical bonds – chemical reactions changes in composition of matter due to making and breaking of bonds (not intermolecular – forces) READ pp. 28-29 Note that it’s not about what’s on the or on the it’s the direction the arrow is pointing. The arrow “left” “right” – always points at the products! law of conservation of mass (matter) is key! Equations must balance make sure you can balance equations by – working through the available equations and checking your answers against the key on the back chemical equilibrium dynamic state in which there is no net change in the concentration of the reactants or the – concentration of the products concentrations are stabilized at a particular ratio Complete Concept Check 2.4 – especially if this is your first biology class! Concept 2.5 Hydrogen bonding gives water properties that help make life possible on Earth – READ pp. 29 37 – Answer the following questions Define the following terms Complete the water FRQ
