State the characteristics of carbon. |
| Answer» Physical Properties of Carbon:Carbon is a unique element. It occurs in many forms. Some of the examples of the pure form of carbon are coal and soot. It is soft and dull grey or black in color. One of the most important compounds of carbon is the charcoal, which is formed when carbon is heated in the absence in of air. It occurs in a number of allotropic forms. Allotropes are nothing but forms of an element with varying physical as well as chemical properties. The density of the different forms of carbon depends upon the origin of these elements. You will find some forms of carbon which are pure and some forms which are not pure like coal which is the mixture of both carbon and hydrogen. | |

Applications of magnetism in different field of science |
|
Answer» \tWe might be using computers in our day to day lives but never wondered the presence of a magnet inside it. Magnetic elements present on a hard disk helps to represent computer data which is later ‘read’ by the computer to extract information.\tMagnets are used inside TVs, Sound speakers and radios. The small coil of wire and a magnet inside a speaker transforms the electronic signal to sound vibrations.\tMagnets are used inside a generator to transform mechanical energy to\xa0electrical energy\xa0where there are other kinds of motors which use magnets to change electrical energy to mechanical energy.\tElectrically charged magnets can help cranes to move large metal pieces.\tMagnets are used in filtering machines which separates metallic ores from crushed rocks.\tIt is also used in food processing industries for separating small metallic pieces from grains etc.\tMagnets are used in MRI machines which are used to create an image of the bone structure, organs, and tissues. Even magnets are used to cure cancer. Hi anchal |

Why are metal called electropostive ions explain with example |
| Answer» The tendency of\xa0metals\xa0to lose electrons inorder to get stability is called\xa0electropositive\xa0nature of\xa0metals. In general most of the\xa0metals\xa0lose electrons from their valence shell due to weak force of attraction on the outermost shell.\xa0Metals\xa0like Na, Mg,Fe, Zn lose electrons and form positively charged\xa0ion. Due to this\xa0metals are called electropositive elements.\xa0Metals are called electro positive elements\xa0because\xa0metals\xa0have a higher tendency to loose electrons. when an element loose electron it gains positive charge. | |

Is fermentation a mode of respiration?support your answer |
| Answer» Anaerobic\xa0respiration\xa0is a type of\xa0respiration\xa0where oxygen is not used; instead, organic or inorganic molecules are used as final electron acceptors.\xa0Fermentation\xa0includes processes that use an organic molecule to regenerate NAD+\xa0from NADH.\xa0Even though\xa0fermentation\xa0happens without oxygen, it isn\'t the same as anaerobic\xa0respiration. ... If that acceptor is oxygen, the process is considered aerobic\xa0respiration. However, some\xa0types\xa0of organisms, including many\xa0types\xa0of bacteria and other microorganisms, can use different final electron acceptors. | |

How to find the redox equation?? |
| Answer» Oxidation and Reduction Reaction:In this reaction, CuO is changing into Cu. That is, oxygen is being removed from copper oxide. Removal of oxygen from a compound is called reduction, so we can say that copper oxide is being reduced to copper. On the other hand H2 is changing into H2O. That is, oxygen is being added to hydrogen. The addition of oxygen to a substance is called oxidation, so we can say that oxygen is being oxidised to water.The chemical reaction in which the oxidation and reduction takes place simultaneously is called redox reaction.\xa0 | |

Write a equation for photolytic reaction which is not decomposition reaction |
|
Answer» Photosynthesis is a photolytic reaction but do not decomposition reaction The interaction of photons with one molecule is photolytic reaction whereas the single compound here breaks into more elements. • For example, in photosynthesis, the plants get their energy from sunlight to form a photo chemical reaction. The process involved in photosynthesis does not constitute decomposition reaction as the energy is not decomposed in any way of a photolytic process.\xa0• The formula of photosynthesis:6CO2 + 6H2O (Sunlight & Chlorophyll) → C6H12O6 + 6CO2\xa0. |
