Yesterday, we did 3 experiment to see the reaction of Metals.
What were the different experiments you completed?
We did the experiment for :
- Metal with acid
- Metal with oxygen
- Metal carbonate with acid.
What observations did you make in each experiment?
- For the metal with acid, the acid bubbles when the metal comes in contact with the acid.
- For the metal with oxygen, when the magnesium catches on fire, it creates a bright light like flash light.
- For the metal carbonate with acid, when the gas from the tube flows to the lime water tube, it creates bubbles and turns the water cloudy.
How can reactants from your experiment be used to predict products?
- This is because metal and acid become metal salt and hydrogen
Metal + Acid —> Metal Salt + Hydrogen
- When metal carbonate and acid will make salt, water and carbon dioxide.
Metal carbonate+ acid —> Salt + water + carbon dioxide
- When metal and oxygen came together, the metal became metal oxide.
Metal + Oxygen —> Metal oxide
What was each experiment testing for?
To see the reaction of the reactants ( metal and another element) and products.
- Metal and acid- to create Hydrogen gas
- metal carbonate and acid- To show predictability in experiments
- metal and oxygen- To join the metal and the oxygen
