2H2 + O2 = 2H2O

OXIDE AND CARBON DIOXIDE

Metal carbonates decompose when heated to form......

Some decompose easier than others

Why? Explain in terms of atoms and what does this mean about melting and boiling points?

WEAK INTERMOLECULAR FORCES BETWEEN THEM.

LESS ENERGY

MEANS LOW BOILING AND HEATING POINTS

THANK YOU!

Precipitation reactions

When 2 insoluble substances react together and form a soluble/ insoluble product?

That product is a precipitate

And Eazy-A

(aka Aeman)

Thermal Decomposition

Example Calcium carbonate is hardest to decompose and copper carbonate is the easiest

Balancing Equations

Up to 3 marks

COMPLETE

H2 + 02 = H20

Rearranging Atoms

Rearranged to form different substances

ATOMS ARE NOT CREATED OR DESTROYED

Same amount of atoms before and after reaction

PRODUCTS have different properties than reactants

AS NO ATOMS BEEN CREATED destroyed, TOTAL MASS OF ATOMS STAYS THE SAME

Chemical Reactions And Reactions Of Calcium Compounds
