What are 5 example of chemical reaction that occur in nature?
Photosynthesis: Conversion of carbon dioxide and water into glucose and oxygen. Rusting of iron: Oxidation of iron in the presence of oxygen and water. Fermentation: Conversion of sugars into alcohol and carbon dioxide by yeast. Decomposition of organic matter: Breakdown of organic compounds into simpler molecules by microbes. Acid-base neutralization: Reaction of an acid with a base to form water and a salt.
How long does it take for an iron filling to rust?
Iron fillings can start to rust or oxidize in a matter of hours or days, depending on the humidity levels and presence of oxygen in the environment. The process of rusting occurs when iron reacts with oxygen and water, forming iron oxide.
What are some examples of chemical and physical changes grade 5?

How can you stop iron from rusting?
We protect iron from rusting byBy converting iron to stainless steel. Stainless steel is the mixture of iron with carbon and other elements such as chromium. Good quality of curtley is made of stainless steel.Galvanising: coating iron with zinc. The iron object is dipped into molten zinc, then removed. On cooling thin layer of zinc is deposed on the object. Gates are made of galvanised iron.Coating it with tin. This process is used to make food cans.Painting it with suitable paints. Iron bridges have to be painted regularly. Can you explain why water paint is not suitable? Because water paint will enhance rusting.Greasing it. Can parts are greased.Oiling it.Coating it with plastic.
How can you clean rust in a steam iron?
Step 1: Scrub the ironing surface with a wet cloth covered with a mild abrasive such as baking soda or table salt. Step 2: Wipe the ironing surface with a clean, damp cloth to remove the residue. Step 3: Fill the iron with equal parts white vinegar and distilled water. Place an oven rack over your sink and position the iron on top, with the steam vents facing down. Plug in the iron and turn it to the steam setting. Run it until the steam stops. Step 4: Fill the iron with plain distilled water and repeat the process. Step 5: To prevent spots in the future, after ironing, empty any leftover water while the iron is still hot. That way, the heat will dry out the steam chamber and prevent any metal particles in the water from rusting.
