Chemical Reactions Draw a diagram showing what happens

Chemical Reactions Draw a diagram showing what happens to atoms in a chemical reaction.

Chemical Reactions Draw a diagram showing what happens to atoms in a chemical reaction. What does a scientist observe that indicates a chemical reaction occurred?

Chemical Reactions Draw a diagram showing what happens to atoms in a chemical reaction. What does a scientist observe that indicates a chemical reaction occurred? How do the diagram and observations relate to the law of conservation of mass?

Chemical Reactions Na + O 2 Predict the product.

Chemical Reactions Na + O 2 What signs are there a chemical reaction took place? How many products are made?

Chemical Reactions Na + O 2 Na 2 O Draw what the atoms are doing. Relate to the law of conservation of mass

Types of Chemical Reactions

Synthesis

Synthesis Reactions

Type of Reaction Definition Synthesis Two or more elements or compounds combine to make a more complex substance Equation A + B → AB A = Red B = Blue C = Green D = Yellow

Decomposition

Decomposition Reactions

Type of Reaction Definition Synthesis Two or more elements or compounds combine to make a more complex substance Decomposition Compounds break down into simpler substances Equation A + B → AB AB → A + B A = Red B = Blue C = Green D = Yellow
