Question THREE Predict what would happen if sodium sulfate solution and calcium nitrate are mixed together. Explain your answer.
Question FOUR Predict what would happen if calcium carbonate powder is strongly heated in a crucible over a blue Bunsen flame. Write down the balanced symbol equation.
Question FIVE Predict what would happen if very finely ground aluminium powder is burnt using a blue Bunsen flame. Write down the balanced symbol equation.
Question SIX Write down the word equation and the balanced symbol equation “When the mixture of iron filings and sulfur powder was heated, it reacted and iron sulfide compound was produced”
Question SEVEN Write down the word equation and the balanced symbol equation “When calcium chloride solution and sodium carbonate solution were mixed together, white, cloudy substance was produced”
