Working With Chemical Equations

A chemical substance that is present at the start of a chemical reaction (the Ingredients)

• Reactant
• Product
• Law of Conservation of Mass
• Molecular Formula

In a chemical equation, what side is the product(s) on?

• Right
• Top
• Bottom
• Left

What is a 'mole' (in chemistry!!)

• A dozen
• A fundamental unit used to measure the amount of a substance
• A common rodent that eats mom's garden
• The mass of any given element

The following Chemical Equation is an Example of _____________________?

• Single Displacement
• Synthesis
• Creation
• Decomposition

Limiting Reactant/Reagent

• A reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be produced
• A quantity that is always calculated and shows the theoretical amount of product that could be produced in an ideal chemical reaction in which there is a
• A conversion factor that relates the amounts in moles of any two substances involved in a chemical reaction
• An estimate of how much a measured or calculated value differs from a true value

In this chemical reaction, CH₄ + 2 O₂ --> 2 H₂O + CO₂, how many moles of water ( H₂O ) would be produced if 2 moles of methane ( CH₄ ) completely reacted in excess oxygen according to the reaction below?

• 2 moles H₂O
• .5 moles H₂O
• 4 moles H₂O
• 2 moles CO₂

What type or Chemical Reaction is seen here: HCL + LiF ---> HF + LiCl

• Double Displacement
• Decomposition
• Synthesis
• Destruction

The Law of Conservation of Mass states that....

• Matter can not be created or destroyed
• Cans, Glass, and Paper must be recycled
• Mass is directly proportional to volume
• Renewable energy must replace fossil fuels

How many particles are in 1 mole?

• 6.02 x 10²³
• 12
• 1.0 x 10³
• 144,000
