SC.912.P.10.1 The student will be able to perform calorimetric calculations to determine how much heat is absorbed or released. q = m c ∆T q = heat in Joules (J) m = mass in grams (g) c = specific heat constant J/g O C ∆ T = T final - T initial

Example  The specific heat of copper is J/g o C. When 5.0g of copper are heated from 22 o C to 35 o C how many joules of energy are used?

SC.912.P.10.1 the student will be able to relate the behavior and kinetic energy of a molecule with the temperature of the substance  Energy is neither created nor destroyed only transferred from one form into another.

Energy is stored in chemical bonds in every compound or molecule  Breaking bonds uses energy Making bonds releases energy

Heat of fusion  When water freezes bonds are made between water molecules Therefore the process is exothermic (releases energy)  When ice melts bonds between water molecules are broken Therefore the process is endothermic (requires energy)

In chemical reactions…  Energy is converted from chemical (bond energy) to thermal and/or sound and/or light energy.

Consider the energy changes in this process

SC.912.P student interpret relationship between the properties such as pressure, volume and temperature as explained by various gas laws  Boyles Law: If pressure goes up, volume goes down  Charles’ Law: if volume goes up, temperature goes up  Gay Lussac’s Law: if temperature goes up, pressure goes up

SC.912.P the student addresses the properties of gases based on kinetic molecular theory 

SC.912.P.8.8 the student will be able to classify different types of reactions  Synthesis Reaction : A + B  AB  Decomposition reaction : AB  A + B  Single replacement reaction: A + BC  AC + B  Double replacement reaction: AB + CD  AD + CB  Combustion reaction: Carbon compound + O 2  CO 2 + H 2 O

Classify 1. CaCO 3  CaO + CO 2 2. P O 2  2 P 2 O 3 3. P O 2  2 P 2 O 3 4. C 6 H O 2  6 CO H 2 O 5. Pb + FeSO 4  PbSO 4 + Fe

SC.912.P.8.8 the student recognizes if a single replacement reaction occurs based on the activity series for metal and halogens  2 AlCl Pb  2 Al + 3 PbCl 2 Will this reaction proceed?

Will this reaction proceed? 3FeCl Al  2 Al Cl 3 + 3Fe
