Why we are balance the chemical reaction |
|
Answer» Following the Rio conference of 1992, most countries undertook to draw up a national strategy for sustainable development. The implementation of these strategies has turned out to be tricky, because it must address very serious issues within economic and political contexts that are marked by strong inertia. The issues appear at every level and affect practically every area of national policy. The various approaches reflect different points of view, and in particular: more or less constrained free market practices, a desire to place people at the heart of the economy, the greater or lesser determination of the various countries in the world, and the balance between short, medium, long, and very long-term interests. Moreover, there is no denying that the interdependence of modern-day economies means that environmental problems must be dealt with on a worldwide level, which does not simplify the implementation of the necessary strategies, particularly because of differences in levels of development.

Explain the electrolysis process of water into hydrogen and oxygen |
| Answer» Take a glass beaker fix two electrodes. The positive electrode acts as anode and negative electrode act as cathode. Fill 1/3 of beaker with water. Take two test tubes. Insert on electrodes. Observe the level of water in the test tubes. Connect the electrodes to a battery. Pass the electricity for a period of time. Later switch off the current and observe the level of water in test tubes. The level of water in the test tubes is decreased. The free space in the test tubes is filled with H2 and O2 gases. Oxygen gas is evolved at anode and hydrogen gas released at cathode. | |

How does ammeter and voltmeter connect in a series |
| Answer» (i) 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.(ii) 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. | |

Explain Human eye and its type |
| Answer» The human eye is a spherical structure which fits in the eye socket in the skull bone. There are following main parts in the human eye.\tPupil: Pupil is the round black spot in front of eye. It regulates the amount of light entering the eyes. Pupil works like aperture of a camera. In case of dim light pupil dilate to allow more light to enter the eyes. In case of strong light pupil constrict allowing less light to enter.\tIrish: Irish is made of muscles. They control the size of opening of pupil.\tLens: Lens lies just behind the pupil. Lens becomes thin to increase its focal length. This enables us to see distant objects clearly. To focus on nearer objects, lens becomes thick to decrease its focal length. But there is a limit. The minimum distance of clear vision is 25 cm. Below this distance, we cannot see things clearly.\tRetina: Retina works like a screen or camera film. Retina is full of light and colour sensitive cells. These cells, upon receiving image send electrical signals to the brain, which processes these information to make a mental image of what we see. The photoreceptor cells in the eye are of two types, viz. rod cells and cone cells. The rod cells are sensitive to dim light. The cone cells are sensitive to bright light and colour. | |
