Apples that reacts with oxygen and iron that are also found in the apple. The oxidation reaction basically forms a sort of rust on the surface of the fruit. You see the browning when the fruit is cut or bruised because of these actions .

In a homemade volcano, when baking soda and vinegar is mixed a violent chemical reaction occurs. This realeases carbon dioxide gas.

I had got an example but i am not sure are they chemical reaction or physical reaction the first is burning wood logs. When the fire touched the logs the logs will be burned and this reaction will form woods to be ashes.

We see plants everyday, and they use photosynthesis to turn carbon dioxide and water to make oxygen and carbohydrates.

when we cook food with cooker everyday,natrual gas is burned, here is a chemical reaction in this situation:CH4+2O2=burn==CO2+2H2O

Sometimes we use acetic acid to remove the water scale in the kettle，because acetic acid can make a chemical reaction with the main ingredient
ReplyDeletein the water scale.The main ingredient of the water scale is MG(OH)2 and
CaCo3.The situation of this reaction is : 2CH3COOH+CaCO3=(CH3COO)2Ca+H2O+CO2↑
Mg(OH)2＋2HAc＝Mg(Ac)2＋2H2O
The acetic acid can write into a short form for HAc

In summer, I'd like to drink coke to keep cooldown. When I open the bottle, soon I can see there is some boiling bubble. After drinking the coke, I always get a hiccup.
ReplyDeleteThe boiling bubble is carbon dioxide. Our stomach has a higher temperature than the coke, so the stomach cannot absorb the carbon dioxide in a short time, the carbon dioxide exhaust from the mouth. And it will take away the heat to make me feel cool.
