In summary, the speaker finds inorganic reactions difficult to balance and as a result, struggles to memorize many equations for exams. They suggest identifying and treating redox reactions differently in order to balance them more easily.

Some inorganic reactions are so tough to balance that keeping the tight timing of exams in mind, I'm forced to learn the whole equation alongwith the stoichiometric equation which makes it very difficult for me to memorize many equations.

in organic chemistry, very rarely is the equation balanced.. and hence i can learn almost 2-3 times more reactions with organic chem. rather than inorganic chem.

what do u suggest i do?

If you can not eyeball the balanced equation after 1 minute, then chances are the reaction is a redox reaction. Redox reactions are incredibly difficult to balance if you don't know the proper procedure. Monitor oxidation numbers. If there is a change, then it is a redox reaction. Once you identify a redox reaction take the following steps.

1.) split into half reactions

2.) Balance all of the atoms except O and H

3.) balance the O's with H20

4.) balance H's with H+

5.) balance the charge with electrons.

6.) combine half reactions, cancel out electrons. Should give you the balanced reaction.

Learning how to balance equations is an essential skill in chemistry. It requires practice and understanding of the fundamental principles of chemical reactions. Here are some suggestions that may help you learn and balance equations more effectively:

1. Understand the basics: Before attempting to balance equations, make sure you have a strong understanding of the basics of chemical reactions, such as the Law of Conservation of Mass and the concept of atomic and molecular ratios.

2. Use a systematic approach: Start by identifying the reactants and products in the equation and their corresponding elements. Then, use a systematic approach to balance the equation, such as balancing the most complex molecules first or balancing the elements with the highest atomic weight.

3. Practice, practice, practice: The more you practice balancing equations, the more comfortable and efficient you will become. Try to solve a variety of equations, including simple and complex ones, to improve your skills.

4. Use visual aids: Some people find it helpful to use visual aids, such as diagrams or models, to understand the relationship between reactants and products in a chemical reaction. This can also help with balancing equations.

5. Understand the reactions: Instead of memorizing the entire equation, try to understand the underlying chemical reactions. This will not only help you balance equations more easily, but it will also deepen your understanding of the subject.

6. Focus on inorganic reactions: Although organic reactions can sometimes be easier to balance, it is important to also focus on inorganic reactions. These reactions are often more complex and require more practice, but they are also critical to understanding many chemical processes.

Remember, learning how to balance equations takes time and practice. Don't get discouraged if you struggle with it at first. Keep practicing and seeking help from your instructor or peers if needed. With determination and a solid understanding of the basics, you will become proficient in balancing equations.
 

1. How do I determine the number of atoms in a balanced equation?

To determine the number of atoms in a balanced equation, you must first identify the elements present in the reactants and products. Then, count the number of atoms of each element on each side of the equation. If the number of atoms is not equal on both sides, adjust the coefficients of the compounds until the number of atoms is balanced.

2. What is the purpose of balancing equations?

The purpose of balancing equations is to ensure that the law of conservation of mass is followed. This law states that matter cannot be created or destroyed in a chemical reaction, only rearranged. Balancing equations allows us to see how atoms are rearranged in a reaction and to accurately predict the products that will be formed.

3. How do I know when an equation is balanced?

An equation is considered balanced when the number of atoms of each element on the reactant side is equal to the number of atoms on the product side. In other words, the equation must be balanced both quantitatively (number of atoms) and qualitatively (types of atoms).

4. What are some tips for balancing equations?

One tip for balancing equations is to start by balancing elements that appear in only one compound on each side of the equation. Another tip is to use the lowest possible whole number coefficients. Additionally, it can be helpful to check your work by counting the number of atoms of each element on both sides of the equation.

5. What are some common mistakes to avoid when balancing equations?

One common mistake when balancing equations is to change the subscripts of compounds in order to balance the equation. This is incorrect because it changes the identity of the compounds and violates the law of conservation of mass. Another mistake is to forget to balance polyatomic ions as a whole unit, rather than individual atoms. It is also important to double check the coefficients of each compound to ensure they are the lowest possible whole numbers.
