What is a chemical reaction?
A process where 1 set of chemical substances react with each other to form a new set of chemical substances.
What can be formed when substances react with one another?
Chemical properties
A+b
Reactants
A-b
Products
What is re-arranged to form different products in reactions?
Atoms
What happens during a chemical reaction?
Chemical bonds of the reactants break and new bonds form to produce the products.
Bond

How do you make traditional beer?
- Soak Ground sorghum and sorghum malt in boiling water. This changed the starches in grain to sugar.
- Add ground maize, ground sorghum malt and inhlease. The inhlese contains yeast, the enzymes in yeast change sugar to ethanol and carbon dioxide
Traditional beer method simplified
- Sorghum starch+water react with each other to form sugar.
2. Sugar+yeast react with each other to form ethanol and carbon dioxide.
What is a chemical bond?
Electrostatic force of attraction between 2 atoms.
Compounds can be broken down in decomposition reactions into other compounds/ original elements by?
thermolysis and electrolysis
