Answer

Brief Explanations:

  1. Reaction 1 - Rusting of iron: The chemical equation is $4Fe + 3O_2+ 6H_2O\rightarrow4Fe(OH)_3$. Iron reacts with oxygen and water in the air to form iron(III) hydroxide, commonly known as rust. You can see it on old iron fences or nails that have been exposed to the elements for a long - time as a reddish - brown flaky substance.
  2. Reaction 2 - Digestion of food: For example, the digestion of starch. The enzyme amylase in saliva breaks down starch ($(C_6H_{10}O_5)n$) into maltose ($C{12}H_{22}O_{11}$). The equation can be written as $(C_6H_{10}O_5)n + nH_2O\xrightarrow{amylase}nC{12}H_{22}O_{11}$. You experience this every time you eat and your body breaks down food to obtain energy.
  3. Reaction 3 - Combustion of natural gas: Methane ($CH_4$) burns in oxygen ($O_2$) to produce carbon dioxide ($CO_2$) and water ($H_2O$). The balanced equation is $CH_4 + 2O_2\rightarrow CO_2+2H_2O$. When you use a gas stove for cooking, this reaction is taking place, and you can see the heat and the blue - colored flame.
  4. Reaction 4 - Ripening of fruits: Ethylene ($C_2H_4$) acts as a plant hormone to speed up the ripening process. For example, it can convert starch in bananas into sugars. Although the exact chemical equations for the complex series of reactions are numerous, ethylene is key in changing the texture, color, and taste of the fruit. You can observe unripe green bananas turning yellow and becoming sweeter over time.
  5. Reaction 5 - Batteries in use: In a common alkaline battery, zinc ($Zn$) reacts with manganese dioxide ($MnO_2$) in the presence of potassium hydroxide ($KOH$). The overall reaction is $Zn + 2MnO_2+2H_2O\rightarrow Zn(OH)_2 + 2MnO(OH)$. When you use a battery - powered device like a flashlight, this chemical reaction occurs to produce electrical energy.

Answer:

Reaction 1: $4Fe + 3O_2+ 6H_2O\rightarrow4Fe(OH)3$. Explanation: Iron reacts with oxygen and water to form rust, seen on old iron items. Reaction 2: $(C_6H{10}O_5)n + nH_2O\xrightarrow{amylase}nC{12}H_{22}O_{11}$. Explanation: Enzyme amylase in saliva breaks down starch during digestion. Reaction 3: $CH_4 + 2O_2\rightarrow CO_2+2H_2O$. Explanation: Methane burns in oxygen when using a gas stove for cooking. Reaction 4: Ethylene - mediated ripening reactions. Explanation: Ethylene converts starch to sugars in fruits like bananas during ripening. Reaction 5: $Zn + 2MnO_2+2H_2O\rightarrow Zn(OH)_2 + 2MnO(OH)$. Explanation: Reaction in alkaline batteries to produce electrical energy for devices.
