There are different methods of balancing a chemical equation. We have already discussed hit and trial method. Today we will go through some examples of balanced chemical equations with answers. Examples of Balanced Chemical Equations 1.CH4 +O2 → CO2 + H2O Ans- CH4 +O2 → CO2 + 2H2O 2.Na+ H2O → NaOH + H2 Ans- 2Na+ … Read more
Through this glass slab experiment, we can easily identify refraction of light. Through this experiment we can find the lateral displacement of light ray after refraction. What is refraction? The phenomenon of change in path of light as it moves from on transparent medium to another transparent medium, is called refraction of light. Define lateral … Read more
