Why acid and base not react with metals |
|
Answer» Metals react with acids and displaces hydrogen from the acids to produce hydrogen gas and metal salt. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. It is this hydrogen gas that burns with a pop sound.Copper does not react with hydrochloric acid because it is below hydrogen in the electrochemical series due to which it does not react liberate hydrogen but reacts with sulphuric acid. Normally acid react with metal and metal are in basic nature so metal doesnot react with metal or bse Both react with metals |

What is the difference between reflection and refraction? Write three points. |
| Answer» Reflection\tRefractionWhen light falls from one medium on the surface of another medium apart from it bounce back in the same medium. This process is called reflection of light.\tWhen light falls from one medium on the surface of another medium it changes its direction and speed. This process is called the refraction of light.In this process, light bounces back.\tIn this process light change path.In this process, light waves bounce off the plane and change direction.\tIn this method, light waves change their direction and speed.In reflection of the light angle of incidence is equal to the angle reflection.\tIn refraction angle of the incident is not equal to the angle of refraction.It occurs in mirrors.\tIt occurs in lenses. | |

What is ohm\'slaw? |
|
Answer» The electric current following throw a metallic wire is directly proportional to the potential difference across its ends and provide its temperature remance the same. At a constant temperature the current flowing through the conductor is directly proportional to the difference across its ends V=IR... Ohm\'s law says at constant temperature voltage is directly proportional to the current flowing in the circuit.V is directly proportional to IV equals to IR, where r is Resistance ( constant of proportionality.) Potential voltage is directly proportional to electric current Whar kind of questions is coming in board |
