Snowman Challenge
Snowman Challenge Rules Work in groups of 3 (at your row) to balance equations When you finish balancing your equations, bring your paper to Ms. Ose to check your answers The first team to have all the correct answers wins a prize Do not begin until Ms. Ose says GO!
Translating Chemical Equations and Properties of Chemical Reactions Notes
What is a chemical reaction? Process of one or more reactants converting to form products with different properties.
Ways to Represent Chemical Equations Using words ◦ Hydrogen (gas) + Oxygen (gas) water (liquid) Using symbols ◦ H 2(g) + O 2(g) 2 H 2 O(l) Symbols are a shorthand way to represent an equation
Evidence of Chemical Reactions Production of a gas Production of a solid ◦ Precipitate – a solid formed as the product of a chemical reaction A color change Temperature change
Translating Chemical Equations Practice Complete the practice at your desk and whatever you do not finish is homework
Exit Ticket For the following chemical reaction: ◦ Solid mercury (II) oxide breaks down when heated, forming the elements mercury and oxygen. Write the word equation Write the balanced formula equation (symbols) ◦ Make sure you include the correct state!
