What is thermite reaction???.. |
|
Answer» When aluminium is react with ferrous oxide then aluminium oxide with energy and iron (in melted form ) are formed this is known as thermite reaction Thank you... Aluminothermy is also known as thermite reaction. Reaction of aluminium metal with ferric oxide is only the thermite reaction. It exerta a lot of heat during this reaction. The process of igniting Aluminium and Ferric oxide is called thermite reaction. This is an exothermic reaction. Iron obtained in this process is in molten state. Fe₂O₃ (s) + Al (s) →Al₂O₃ + 2 Fe(l) + Heat Thermite reaction used for the welding of rails (joining metals) called as thermite welding. |

|
| 65714. |
Why sun rises reddish early in the morning |
|
Answer» During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the sun and the sky appear red☺️ Due sccaterring of light all the 6 colour except red are scatter in the wayonly red colour travell maximum distance due to its higher wavelength. |
|
| 65715. |
Why do we use sin in refractive index |
| Answer» When there is an interface between two mediums, which is when Snell\'s law comes into play, the speed of light depends on the refraction index of the two mediums*, so it changes from one to the other. It is slower in the medium with the higher refraction index. | |
| 65716. |
Why are Ionic compounds brittle?? |
|
Answer» Ionic compound are hard and brittle due to strong electrostatic force . Ionic compounds are insulator in solid form but good conductor in solution form . A bond formed between two atoms,molecules or compounds by the complete transfer of electrons is called ionic compound Ionic compounds are hard and brittle because in ionic compounds the ions are tightly packed.. |
|
| 65717. |
what is balance electron |
| Answer» A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction. | |
| 65718. |
How do we know that after a chemical reaction heat is evolved |
|
Answer» chemical reactions,\xa0bondsbetween\xa0atoms\xa0in the reactants must be broken, and the atoms or pieces of\xa0molecules\xa0are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved on making new bonds, and the net result is the\xa0absorption\xa0of energy. Such a reaction is said to be endothermic if the energy is in the form of\xa0heatThe opposite of\xa0endothermic\xa0is exothermic; in an\xa0exothermic reaction, energy as heat is evolved If more energy is released than the energy consumed, then heat is evolved and the reaction is known as an exothermic reaction |

What is tetravalent.? |
|
Answer» An element like carbon which have four electrons in its valence shell have an tetravalent Carbon has atomic number 6 and atomic mass 12. Its electronic configuration is 2,4 .Since it has 4 valence electrons,it is tetravalent in nature.The valence of an element is the maximum number of hydrogen or chlorine atoms that can combine with an atom of the element. Carbon is in Group 14 of the Periodic Table, so a carbon atom has four valence electrons. It can also bond with four atoms of chlorine. The prefix tetra- means four, so carbon is tetravalent. |

State ohms law. Also prove it mathematically |
|
Answer» According to the Ohm\'s law, a German scientist observed stated that potential difference(V) is directly proportional to the current(I) and resistance (R). Therefore V=IR According to this law the Voltage established across the two ends of wire is directly proportional to the current flowing through it. According to ohms law potential difference of a battry is directly proportional to current in a circuitV propn I ( v is volt and i is current)V=RI (here R is constant) |

In absence of muscles cells how do plants cells show movements |
| Answer» Plants cells shows two types of movements :-Tropic movements are growth movements in response to an environment stimulus. This type of movement may occur in response to gravity (gravitropism), light (phototropism), water (hydrotropism), chemical (chemotropism) etc.Nastic movement are independent of the direction of stimulus. This type of movement may occur in response to chemicals, temperature, touch etc.This shows that plant cell can shows movements in response to different stimuli although they do not have muscle cells. | |

What is the defination of monohybrid cross? |
|
Answer» Thanks...... Yogita The cross in which just two contrasting characters are studied is called monohybrid cross. Monohybrid cross\xa0is the study of inheritance of one pair of contrasting characters. Through monohybrid cross experiments, Mendel proposed the Laws of Dominance and Law of segregation. For example, Tall stemmed plants are crossed with short stemmed plants. A new ratio of 3:1 is formed in the F2 generation. 75% individuals are dominant and 25% are recessive individuals.\xa0 |

What are the different methods of asexual reproduction |
|
Answer» Forms of asexual reproduction are-FissionFragmentationVegetative propagationBudding Hi Neha In fragmentation, a “parent” organism is split into multiple parts, each of which grows to become a complete, independent “offspring” organism. This process resembles budding and vegetative propagation, but with some differences. For one, fragmentation may not be voluntary on the part of the “parent” organism.The methods of asexual reproduction vary greatly among different types of species.Spores. Some protozoans and many bacteria, plants and fungi reproduce via spores. Fission. Prokaryotes and some protozoa reproduce via binary fission. Vegetative Reproduction. Budding. Fragmentation. Fission BuddingRegeneration FragmentationSpore FormationVegetative Propagation |
