What is common ion effect.? |
| Answer» When a compound is ionized in a solution it forms cations and anions . When we add a more ionic substance to the solution which have a common ion as in the previous compound then it affects the equilibrium and may reverse the process. This effect of a common ion is called common Ion effect. | |

By burning a candle,why it\'s flame goes upward even when the burning candle is turned upside down? |
| Answer» It\'s precisely\xa0because\xa0of gravity that they go upwards. The gravity is pulling on both it and the air. The air, being cooler and thus denser, puts pressure on the lighter flame when it is displaced. That pressure is stronger on the bottom than the top, and pushes the flame upwards. That\'s buoyancy; it\'s the same thing that makes boats float.When the gravity is absent, the cooler, denser air doesn\'t flow downwards. It continues to put pressure on the flame from all directions, which means it comes out as a sphere rather than going upwards.\xa0 | |

Why d block called transition elements |
| Answer» A: The position of d-block elements is in between the s-block and p-block elements in the periodic table. These d-block elements are called transition elements because they exhibit transitional behaviour between s-block and p-block elements.Their properties are transitional between highly reactive metallic elements of s-block which are typically ionic compounds and the elements of p-block which are largely covalent. | |

Why Oxygen has bond order 1 |
|
Answer» Oxygen don\'t have bond order 1 it has bond order 2The bond order 1 is of peroxide The answer is 2. In ozone molecule there are two possible resonating structure in which double and single bond exist between oxygen atoms, hence the bond order will be average of both that is 1.5. |
