What do all these have in common?

To to Balance the Elements

To write a word equation (E)

To state the link between reacting

masses and predict masses

in a reaction. (E)

To calculate the mass of a

reactant or product in a

reaction given the other masses

in the reaction (C)

To balance a symbol equation

(A)

Equation Product Reactant

Mass Balanced Symbol

Reaction

Naming Compounds

•Metal goes first

•Metal + oxygen = Metal oxide•Metal + nitrogen = Metal nitrate•Metal + CO2 = Metal carbonate

•Fluorine, bromine and chlorine fluoride, bromide or chloride

Use the rules to name these compounds

•Name the compound made from sodium and fluorine.

•What compound is made from oxygen and zinc?

•What compound is made in the reaction between bromine and potassium?

Word Equations

•Used to show reactants and products

Reactant + Reactant Products

•E.g. Magnesium + Oxygen Magnesium Oxide

•Write the equations for the compounds you have just named

Symbol Equations

•Much faster than word equations

•E.g. Mg + O2 MgO

•Write the symbol equations for the word equations you have just completed

Balancing Equations

•The number of atoms on each side of the equation must balance

•E.g Mg +O2 MgO

•There must be the same number of Mg and O on each side

Balancing Equations

•Are the equations on the worksheet balanced?

•Finished level 1?

•Try level 2!

Rules▫You can’t change the formulae▫You can only multiply how many of that

compound/molecule there is ▫You should have the same number of each

element on each side of the equation

Reacting Masses

•The mass of the reactants will always = the mass of the products

Now you try

•FeCO3_________> FeO +

CO2

•Step 1: Make sure the equation is balanced

•Step 2: If 3.0g of CO2 is produced from 7.8g of FeCO3, how much FeO was made?

Objectives Completed •To state the link between reacting masses

and predict masses in a reaction. (E)• To calculate the mass of a reactant or

product in a reaction given the other masses in the reaction (C)
