Does science seem fascinating yet complicated to you simultaneously? You’ve always been a curious kid who wanted a practical explanation of everything happening around us and wanted to understand how these chemical reactions would help you.
If you’re a Sci-fi fan, you would know how scientific theorems, formulas, and equations are regulated in daily life. The same goes for chemical reactions. You’ll find them useful in your day-to-day life.
Class 10 is a crucial stage in a student’s life, as the score and the interest you get in this class technically decides your future. You need to understand the concepts better to understand the problems clearly.
If you have these queries, you’re at the right place. Here we’ve jotted down all the chemical reactions useful in the day-to-day and all the essential chemical equations and chemical reactions in class 10.
5 Reactions that help in day-to-day life
You’ve often heard of the term photosynthesis in the biology section of your science textbook. Photosynthesis is the chemical process in plants converting carbon dioxide and water into plant food, oxygen, and glucose. Here’s the chemical equation for the same.
Equation- 6CO2+ 6H2O → C6H12O6+ 6O2
2. Acid-base reactions
This reaction usually occurs when an acid (vinegar, carbonic acid, etc) combines with the bases like baking soda and vice versa. You can take the example of baking soda with vinegar to form carbon dioxide, water, and sodium acetate.
Equation- NaHCO3 + HC2H32→ NaC2H3O2+ H2O + CO2
It is the basic process of oxidation which means the result of the reaction due to the oxygen. It happens with iron, and it gives a brown rusty layer. This happens due to the oxidization of the topmost layer of iron. You can see these layers form over other metals as well.
Equation- Fe + 3O₂ + xH₂O → Fe₃O₄ . xH₂O
Note: You can also refer to Chemistry chapter 1 for class 10 for further reference
4. Aerobic Cellular Respiration
A process of cellular respiration happens in the presence of oxygen gas to convert food into energy. It creates a chemical reaction between oxygen and glucose to form water or a chemical equation.
Equation- C6H12O6+ 6O2→ 6CO2+ 6H2O + energy
5. Anaerobic cellular respiration
Normal cellular respiration does not require oxygen to produce energy. It is the foremost step in cellular respiration which does not require oxygen. It usually produces less amount of energy than aerobic cellular respiration. Yeast and other bacterias use anaerobic respiration to produce vinegar and other products.
Equation- C6H12O6→ 2C2H5OH + 2CO2+ energy
Overall Chemistry Equations for Class 10
There’re a lot of chemical reactions, but we’ll talk about the most important ones, which are a part of your chemistry class 10 syllabus as well. So there’re 8 reactions in total, which you’ll study today:
- Combination Reaction
In a combination reaction, two or more elements or molecules combine together chemically to form a single molecule or compound.
Equation- 2CO (g) + O2(g) → 2CO2(g)
- Redox Reaction
In redox reactions, both oxidation and reduction take place simultaneously. Oxidation is the addition of oxygen whereas reduction is the removal of oxygen or we can say the addition of hydrogen.
Equation- Zn + CuSO4→ ZnSO4+ Cu
- Decomposition reaction
In a decomposition reaction, molecules or compounds break down into two or more substances. It is usually considered the exact opposite of the chemical synthesis process.
Equation- 2NaCl → 2Na + Cl2
- Combustion Reaction
It is a high-temperature exothermic reaction that releases energy, usually in the form of heat. A chemical reaction between the fuel and the oxidants forms water, heat, and smoke.
Equation- CH4+ 2O2→ CO2+ 2H2O
- Precipitation Reaction
In this reaction, an insoluble solid is formed due to the combination of two ionic bonds of an aqueous solution. These insoluble salts are formed in precipitation form called precipitates.
Equation- AgNO3(aq) + KCl(aq) ↔️ AgCl + KNO3(aq)
- Single Displacement Reaction
In this reaction, one element or molecule is replaced by another compound. In other words, more reactive elements replace the less reactive elements from the salt.
Equation- K + NaCl → KCl + Na
- Double Displacement Reaction
A chemical process involves rearranging two aqueous ionic compounds with two other ionic compounds or producing two new compounds.
Equation- HCl + NaOH → H2O + NaCl
- Neutralization Reaction
A chemical reaction where acids and bases react together and form water and salt.
Equation- HCl + NaOH → HOH + Salt
You can look at more examples to check your understanding and knowledge of the particular area. So this ends the detailed analysis of all the chemical reactions and all the reactions covering class 10.
Chemistry is a fascinating subject that deals with multiple elements and solutions, which helps in studies and real life. I hope, this article will clear all your queries and motivate you to move further.
