Why should a magnesium ribbon be cleaned before buring in air |
|
Answer» Mg ribbon should be cleaned before burning in air coz it is a highly reactive metal and hence, it reacts with atmospheric oxygen. This results in the formation of Mgo which prevents further reaction of the metal. Magnesium ribbon is cleaned before burning it in air this is done to remove the layer of magnesium oxide and magnesium carbonate from the surface of magnesium ribbon these are formed as a result of reaction with atmospheric oxygen, it is cleaned using sand paper after which it burns smoothly We should clean ribbon before burning because in presance of oxygen theunwanted layer are covered in surfaces of magnesium Mg is very reactive metal .when exposed to air it react with o2 and form MgO 2Mg +O2 ➡2 MgO Hence we clean before burning in air. Thank you very much Aadya Singh ???????? Magnesium ribbon should be cleaned before burning in air to remove it\'s protective layer of magnesium oxide so that it can ready to combine with the oxygen of air. |

Is there a difference in how sugar and food taste if your nose is blocked? |
| Answer» A\xa0lot of the flavour of food comes in through the nose. When you chew, chemicals are released into your mouth and some go up the back of your throat into your nose. Your tongue is not as refined at telling flavours apart, so your nose is an important part of tasting. When you have a cold, your nose gets blocked up and the chemicals from the food can’t get through. This is why food can taste bland or different. | |

What are amphoteric oxides? Give 4 examples. |
|
Answer» Metal oxides which react with both acids and bases are called amphoteric oxides. Example: Zn, Al thanks to all thanks to both of you Metal oxides such as aluminium oxide and zinc oxide shows acidic behaviour as well as basic behaviour . They react with acid as well as base and produces salt and water . These oxides are called amphoteric oxides Those metal oxides which show basic as well as acidic behavior is called amphoteric oxide. Ex- Aluminum, Zinc , Copper, Lead. Such metal oxides which react with acids as well as bases to produce salts and water are known as amphoteric oxide Example - aluminum oxide, zinc |

Differentiate between AC and DC generator |
|
| Answer» | \t1DefinitionAC generator is a mechanical device which converts mechanical energy into AC electrical power.DC generator is a mechanical device which converts mechanical energy into DC electrical power.2Direction of CurrentIn an AC generator, the electrical current reverses direction periodically.In a DC generator, the electrical current flows only in one direction.3Basic DesignIn an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.In a DC generator, the coil through which the current flows rotates in a fixed field. The overall design is very simple but construction is complex due commutators and slip rings.4CommutatorsAC generator does not have commutators.DC generators have commutators to make the current flow in one direction only.5RingsAC generators have slip-rings.DC generators have split-ring commutators.6Efficiency of BrushesSince slip-rings have a smooth and uninterrupted surface, they do not wear quickly and are highly efficient.Both brushes and commutators of a DC generator wear out quickly and thus are less efficient.\t | |

What is the function of A) nasal cavity b) diaphragm c) alveoli |
|
Answer» A. It is used to remove the dust particles before entering into lungsB. It is used to maintain the pressure of lungsC. It is the site for the exchange of gases My pleasure thanku to all for the answer.... The function of alveoli is to get oxygen into the blood stream for transport to the tissues, and to remove carbon dioxide from the blood stream........ I hope u clear it.. ?? Diaphragm - The diaphragm is the major muscle of respiration. As the diaphragm contracts, it increases the length and diameter of the chest cavity and thus expands the lungs. This reduces the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest walls pushes air out of the lungs. A) Nasal cavity1 It is a passage from which the air enters in the body. 2 In this passage air is filtered, the dust particles and small organisms does not enter the body. 3 It makes the cold air favorable to our body temperature. B) Diaphragm 1 It contracts makes lungs push upword to increase the surface area to such maximum oxygen. 2 It relaxes and alow the lungs to push out the carbon dioxide out of the longs. C) Alveoli1) It increases the surface area for absorption of oxygen. 2) It exchange the oxygen and carbon dioxide from the blood vessel. Alveoli - alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to move between lungs and blood stream. Nasal cavity - The function of nasal cavity is to warm, moisture and filter air entering the body before it reaches the lungs. |
