The following chemical reactions took place in Activity 1 (Everything Has Changed) procedure A to E.
1.Iron reacts with copper sulfate (CuSO4) and forms iron (II) sulfate (FeSO4) and copper.
2. Magnesium combines with oxygen gas (O2) to produce magnesium oxide
3. Hydrogen peroxide (H2O2) in the presence of manganese dioxide (MnO2) produces water and oxygen gas.
4. Acetic acid (CH3COOH) and sodium bicarbonate (NaHCO3) produce sodium acetate with the release of carbon dioxide (CO2) gas and water.
5. Copper sulfate (CuSO4) reacts with sodium hydroxide (NaOH) to produce insoluble copper (II) hydroxide Cu(OH)2 and sodium sulfate (Na2SO4 ) solution.
