Differentation between calcination and roasting? |
|
Answer» Calcination is heating of carbonate ores in limited air Roasting is heating sulphide ores in excess airThese are used in order to reduce carbonate and sulphide ores to oxide form •calsination is the process in which carbonate ore is heated.•During this process lots of CO2 gas is released.•For example:CaCO3-------->CaO+ CO2.*Roasting is the process in which sulphide ore is hested.*During this process lots ofSO2 gas is realesed.*For example:HgS+O2------->HgO+SO2. |

Why is heat evolved during the reaction of acid and base |
|
Answer» For weak acids and bases, the heat of neutralization is different because they are not dissociated completely and during dissociation some heat is absorbed - total heat evolved during neutralization will be smaller.HCN + NaOH → NaCN + H2O; ΔH = -12 kJ/molThe heat of ionization in this reaction is equal to (–12 + 57.3) kJ/mol = 45.3 kJ/mol. because it is an exothermic reaction |

What is dailysis |
| Answer» Dialysis is primarily used to provide an artificial replacement for lost kidney function (renal replacement therapy) due to renal failure. Dialysis is the artificial process of eliminating waste (diffusion) and unwanted water (ultrafiltration) from the blood. In a healthy man, kidney does this process naturally. Some people may have damaged or failed kidneys which no longer filter toxins from the blood. They do purify their blood through dialysis. | |

What is the difference between principles of electric motor and electric generator |
|
Answer» Thanks for the answer Electric generator works on the principal of electro-magnetic induction i.e. when a conductor is rotated in magnetic field, current is induced. Electric motor works on the principal of magnetic effect of electric current i.e. when a current carrying conductor is placed in magnetic field, it experiences force and starts rotating. |

Can any one tell me about three types of decomposition reaction??? |
|
Answer» Types of Decomposition ReactionsDecomposition reactions can be classified into three types:\tThermal decomposition reaction: Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance.\tElectrolytic decomposition reaction: Electrolytic decomposition may result when electric current is passed through an aqueous solution of a compound. A good example is the electrolysis of water.\tPhoto decomposition reaction: A photo decomposition is the type of decomposition reaction in which the reactant is broken down to its constituents by photons. In thermal heat is produced in photochemical decomposition it is done by sunlight and electrolytic decomposition is done by use of electricity Okk thnx chetna.. Chetna photolytic decomposition light ke presence me hota hai na?? Yess.......1.thermal decomposition 2.photochemical decomposition 3.electrolytic decomposition |

Explain,the cleaning action of soap |
| Answer» Soap is a mixture of sodium salts of various naturally occurring fatty acids. Air bubbles added to a molten soap will decrease the density of the soap and thus it will float on water. If the fatty acid salt has potassium rather than sodium, a softer lather is the result.Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.When soap is added to water, the ionic-salt end of the molecule is attracted to water and dissolved in it. The non-polar hydrocarbon end of the soap molecule is repelled by water. A drop or two of soap in water forms a monolayer on the water surface as shown in the graphics on the left. The soap molecules "stand up" on the surface as the polar carboxyl salt end is attracted to the polar water. The non-polar hydrocarbon tails are repelled by the water, which makes them appear to stand up. | |

How nervous tissue maintain muscular movement |
|
Answer» The dendritic end at the nerve cell set an impulse forming a reflex. Now spinal cord sends the information to the effector via the motor neurons and they remove their point of contact from that harmful stimuli by changing the muscular tissues. Muscular tissue changes because of the alteration by various protiens that change both shape and their arrangements to give muscle cells a new arrangement\xa0 The nervous tissues maintain the muscle movement. They have point called axons which transfer the brains message to the relative muscle and carry out the action. The brain send the message through the tendons and axons to the the point in action. This whole process is maintained by the nervous . |

define define heterotrophs and aototrophs |
|
Answer» Autotrophs: The organisms which are capable to prepare their own food by the process of photosynthesis are called autotrophs. They are also called producers. For example: green plants.Heterotrophs: The organisms which are not capable to prepare their own food by the process of photosynthesis but depend directly on plants for their food are called heterotrophs. For example: rabbit, cows. Autotrophs means who made their food by itself Ex PlantsHeterotrophs means who dont made their food by itself ex animals |
