Journal Entry:

Write the balanced chemical equation when potassium metal bonds with solid sulfur.

Learning Intentions

• You will learn how to predict what the products of a reaction will be based on the reactants.

• You will learn how synthesis, decomposition and combustion reactions look in a real chemical reaction.

• You will learn how to represent a real chemical reaction into a chemical equation.

• You will make sure all you reactions are following the conservation of mass law by balancing appropriately.

Closing Task:

You can write a balanced chemical equation when only given the reactants in words.

Content Standards being covered:   

LO 1.17 You can express the law of conservation of mass quantitatively and qualitatively using symbolic representations and particulate drawings.

LO 1.18 You can apply conservation of atoms to the rearrangement of atom in various processes.

LO 3.1 Students can translate among macroscopic observations of changes, chemical equations and particle views.

LO 3.2 The student can translate an observed chemical change into a balanced chemical equation and justify the choice of equation type (molecular ionic or net ionic) in terms of utility for the given circumstances.

SP 1.1 The student can create representations and models of natural or man made phenomena and systems in the domain.

SP 1.4 The student can use representations and models to analyze situations or solve problems qualitatively and quantitatively.
