FAQs on Chemical Reactions and Equations - 1 Video Lecture - NCERT Video Summary: Class 6 to Class 12 (Hinglish) - UPSC
| 1. What are chemical reactions and equations? |  |
Chemical reactions are processes in which substances undergo chemical changes to form new substances with different properties. Chemical equations are symbolic representations of these reactions, showing the reactants on the left side and the products on the right side, separated by an arrow.
| 2. How are chemical reactions represented in chemical equations? | |
Chemical reactions are represented in chemical equations by using chemical formulas to indicate the reactants and products. Reactants are written on the left side of the equation and products on the right side, separated by an arrow. The coefficients before the formulas indicate the relative amounts of each substance involved.
| 3. What is the importance of balancing chemical equations? | |
Balancing chemical equations is important because it ensures that the law of conservation of mass is obeyed. According to this law, the total mass of the reactants must be equal to the total mass of the products. Balancing the equation by adjusting the coefficients ensures that the number of atoms of each element is the same on both sides of the equation.
| 4. How do you balance chemical equations? | |
To balance a chemical equation, you can follow these steps:
1. Start by counting the number of atoms of each element on both sides of the equation.
2. Adjust the coefficients in front of the formulas to make the number of atoms of each element equal on both sides.
3. Use the lowest whole-number ratios possible.
4. Check that all the atoms are balanced after adjusting the coefficients.
| 5. Can chemical equations predict the outcome of a reaction? | |
Chemical equations can provide information about the reactants and products involved in a reaction, but they do not predict the actual outcome of a reaction in terms of yield or rate. Other factors such as reaction conditions, catalysts, and equilibrium constants influence the actual outcome of a reaction.
