PLEASE HELP Step 2: Predict the products of a chemical reaction.
a) Use your knowledge of atoms, bonding, and the periodic table to complete the chemical equation
and predict the products of the chemical reaction on your paper. Label this equation “Initial
Prediction.”
CH4 + O2
Step 3: Explain your prediction.
a) Create a new blank document. Type your name at the top.
b) Write a few paragraphs predicting the products of the chemical reaction and explaining why you
made this prediction. Your document should:
i. identify the products of the chemical reaction.
ii. explain why these are the products based on trends in the periodic table (the number of
valence electrons, electronegativity, etc.).
iii. identify the types of bonds in the reactants and products.
iv. identify the number of each type of bond in the reactants and products.
v. identify the type of reaction.
c) Label these paragraphs “Initial Explanation.”
Step 4: Create Lewis dot diagrams.
a) Draw Lewis dot diagrams of the reactants and products on the paper with your chemical equation.
b) Select a different color to use for each element in the chemical reaction. Use your chosen color
for the element’s symbol and for its valence electrons.
c) Label these diagrams “Lewis Dot Diagrams.”
Step 5: Review and revise your prediction and explanation.
a) First, review your initial prediction and explanation by comparing it to your Lewis dot diagrams. If
the results of your Lewis dot diagrams are different from your initial prediction, you will need to
revise your prediction and explanation. See Step 5d.
b) Next, review your prediction and explanation to determine whether they adhere to the law of
conservation of mass. If they do not, you will need to revise your prediction and explanation so
that mass is conserved. See Step 5d.
c) Finally, determine whether your explanation addresses trends in the periodic table and how they
can be used to predict outcomes of chemical reactions. If it does not, you will need to revise your
explanation to include a discussion of periodic trends and how they help predict the outcomes of
chemical reactions. See Step 5d.
d) Write your revised chemical reaction on the same paper as your initial chemical reaction and
your Lewis dot diagrams. Label the equation “Revised Prediction.” Write your revised explanation
below your initial explanation in the same document. Label it “Revised Explanation.” Be sure that your revised explanation includes all of the information necessary to address Step 3b and Steps 5a–c
