Cramming?

I know there's a lot of people cramming for the test. If you need any help with oxidation rules, I found this to be really helpful when I was studying!!

Reaction Overview

Studying for the test tomorrow, I thought it would be helpful to share a summary of reactions.
In a double replacement
It forms a solid
2 ionic compounds that are both aq
AB+CD->AD+BC
In Acid/Base
Form water
H+ +OH- as reactants
Bc+BOH->Bx+H2O
In Redox
Transfer of electrons
Single replacement
A+BC->AC+B
Combustion
Compound + O2 -> 
Synthesis
A+B->C
Decomposition
C->A+B

REDOX Reactions Lab

Yesterday we conducted a lab with reactions using metals and solutions.
Included  are pictures from the lab, showing the interesting reactions of metals when reacted with solutions. Many trials did not react, but those that did produced things such as bubbles and smoke.

Acid Base Reactions

Acid Base Reactions
In an Acid Base Reaction, the driving force is the production of water. These reactions will produce a salt and water as products. Salt= cation of base and anion of an acid

A solution of aq nitric acid and aq potassium hydroxide are mixed in a titration
Molecular: HNO(aq) + KOH (aq) --> KNO3 + H2O (l)
Net: H(aq) + OH(aq) --> H2O (l)

Chemical Reactions

Chemical Reactions

Sensory Clues a change is taking place

  • color has changed
  • a solid forms
  • bubbles form (in a liquid)
  • Heat and/or a flame is produced, or heat is absorbed
Heat is Enthalpy = H
Delta H = Change in enthalpy

CHEMICAL REACTION LABS!
These are the pictures of products from our chemical reactions lab on Friday.
