Explain human heart functioning. |
| Answer» The function of human heart :-* It is a four chambered structure consisting - the right auricle , the left auricle , right ventricle and left ventricle.* The Auricles are smaller and placed above the ventricles. Auricles are partitioned by a muscular called septum.* The right auricle receives the deoxygenated blood from all parts of the body except the lungs. It pumps this blood into the right ventricle. Then , the right ventricle pumps the deoxygenated blood to the lungs. The left auricle receives oxygenated blood from the lungs through pulmonary veins. It pumps this blood into the left ventricle. The left ventricle pumps the oxygenated blood to the distant organs in the body.* Each auricle communicates with the ventricle of its side by a pore which is guarded by valves. These valves allow the blood to flow from the auricles to the ventricles but check its return to the auricles. Thus , the heart there is a complete separation of oxygenated and deoxygenated blood. The heart is enclosed in a double membrane called pericardium. It contains fluid which protects the heart from any shock or mechanical injury.*The heart collects blood through both the auricles and then distributes it through ventricles. The action of heart includes contraction and relaxation of the auricles and ventricles.* A contraction of heart is called systole and diastole. The contraction and relaxation occur in an automatic rhythmic fashion. The auricles and ventricles contract alternately. The rhythmic contraction and relaxation of heart is called a heart beat. | |

Why ions conduct electricity. |
|
Answer» Ions have positive ions and also negative ions negative ions attract positive ions and this process has created an electric current with conducting materials like metals etc and thus conduction occurred ions conduct electricity when in liquid or molten states because then there particles can move freely and can conduct electricity. But when they are in solid state there particles are bonded tightly so they do not conduct electricity in solid form. Because ions are charged particles |

why there is no reaction take place if we dissolve acid into acid??? |
|
Answer» When acid dissolve in water they give H+ ion and then acid react with other element. . If dissolve acid into acid ther is no reaction take place because it will not give H+ ion. Thus \'there is no rxn Two acid does not react because both of them.have H+ ion common so they will not react. Because their ions are not separated so they can react with other ion to which they have more affinity. But in water their ions are separated and when another substance comes and one of the element have more affinity to combine with other element of another acid then,they react and form new substance. Even if we put two acid in water and elements have no more affinity towards other elements of another substance then also no reaction will take place. |

Reflex arc |
| Answer» Reflex action in an involuntary action by the body to external stimuli, in which we cannot control ourselves. Reflex actions often bypass the brain altogether to occur very quickly.There are a number of different reflex pathways in the body. A classic example of a reflex pathway can be observed by touching a hot object. Whenever our hand touches a hot object, it triggers a reflex. Signals from the stimulus are transmitted to the spinal cord along the reflex pathway and the spinal cord activates motor neurons, causing the hand to pull away from the hot object. | |

Magnesium ribbon ko burn karne se phele sand paper se kyu saf karte ha |
|
Answer» When magnesium ribbon comes in contact with the oxygen present in air, a layer of magnesium oxide is formed on the surface of the magnesium ribbon. This layer will act as a barrier and will not allow magnesium ribbon to burn.So, to remove this layer, a magnesium ribbon is cleaned with sand paper before burning in air. This is due to the formation of white layer |

Why do gold and platinum not corrode in moist air. |
| Answer» Gold and platinum are least reactive metals. They do not react with the atmospheric oxygen and water.Corrosion of some metals like aluminium protect the inner metal. When aluminium corrodes it forms a thin layer of alumium oxide on the surface of the metal. This layer prevents the corrosion of the metal inside. | |

Why should a chemical equation be balanced? |
|
Answer» According, of law of conservation of mass matter cannot be created nor be destroyed i,e; total mass of element on reactant side is equal to total mass of element on product side that\'s why to make reactant side equal to product side we need to balance a chemical equation Because of the law of conservation of mass The chemical equation should be balanced because it should satisfy the law of conservation of mass that is mass of each element in the reactant is equal to the mass of each element in products. A chemical equation should be balanced to satisfy the law of conservation of mass. |

Why ammeter is placed in series whereas voltmeter in parallel? |
| Answer» The internal resistance of the ammeter is very low. If we connect it in series, then the maximum current can flow through it. So the accurate current should be measured. If we connect it in parallel then the accurate current can’t be measured.The internal resistance of the volt meter is very high and it is used to measure the potential difference between the two points. If we connect it in series, then there is no flow of current in the circuit because of high resistance. And no use of connecting it in series because the potential difference between two points on the same line is zero | |
