Diffrence between endothermic and exothermic ? |
|
Answer» Exothermic reaxn are those reaxns in which heat is evolved in any form of energy while endothermic reaxn are those reaxns in which heat is absorbed in any form of energyTRICK-Exothermic, ex for exitThis means heat is produced Endothermic, en for enterThis means heat is absorbed Chemical reaction that release energy in the form of heat, light, and sound are called exothermic reaction. for ex. C+O2 - CO2 + heat energy. Chemical reaction that absorb energy or require energy in order to proceed are called endothermic reaction. for ex. N2 + O2 in the presence of heat 2NO |

Why is sodium sulphate neutral in nature and sodium carbonate basic in nature? |
| Answer» Sodium sulphate salt is made by reaction of sulphuric acid (strong acid) and sodium hydroxide (strong base). Thus, on combining, the opposite effects of acid and base neutralize each others effect completely leading to the formation of a neutral salt.On the other hand, sodium carbonate salt is made by reaction of carbonic acid (weak acid) and sodium hydroxide (strong base). On combining, the basic character will be more as a weak acid can not neutralize a strong base completely. So, the salt formed is basic in nature. | |
| 63008. |
What is combination reaction?Give an example |
|
Answer» The reaction in which two or more substance combine together to form a new substance,is known as combination reaction....Ex--> 2Mg+O2------------->2MgO.... C+O2----------->CO2. Reactions in which two or more substances react to form a single substance is called combination reaction. Eg:- CaO + CO2 --> CaCO3 The reaction in which a single product is formed from two or reactants is called combination reaction.For example - Carbon +Oxygen =Carbondioxide. |

Name and functions of plant hormone |
| Answer» There are five different types of plant growth regulators.Auxin:\tAuxin helps in cell enlargement by increasing the plasticity of the cell wall.\tAuxin helps in promoting the growth of the plant’s tissue. Auxin is responsible for the phototropism and geotropism.\tAuxin helps in promoting root initiation and stem cutting in plants.\tAuxin inhibits the growth of lateral bud by stimulating the production of ethylene.Cytokinins\tCytokinins help in stomatal opening.\tCytokinins help in delaying the senescence of leaves.\tCytokinins promote the expansion of cotyledons.\tCytokinins are involved in the enlargement of stem cells.Gibberellins\tGibberellins help in controlling the elongation of the stem in young shoots.\tGibberellins help in seeds germination, enzyme production and food production, which is required for the new cells to grow.\tGibberellins help in increasing the number of fruits, the size of a fruit and also delay the ripening of fruits in citrus plants.\tGibberellins are also involved in seed germination.Ethylene\tEthylene helps in stimulating fruit ripening and determining the *** of a flower.\tEthylene is involved in the production of female flowers in a male plant.\tEthylene helps in the root initiation of plants.\tEthylene increases the speed of senescence.Abscisic acid\tAbscisic acid helps in promoting bud dormancy and senescence of leaves.\tAbscisic acid helps in the closing of stomata during Transpiration.\tAbscisic acid inhibits detachment of plant parts.\tAbscisic acid plays an important role in seed development, maturation and dormancy. | |

Digested system explain |
| Answer» In mouth salivary glands secrete saliva (salivary amylase) it change starch into sugar. Teeth chew and grind the food. Tongue roll and taste the food. Food passes from mouth to oesophagus by paristaltic movement. Food enters into stomach where gastric juices like pepsin, hcl, mucus are present. Pepsin breakdown protein, hcl makes surrounding acidic and mucus protect stomach from getting corrode. Then in small intestine, liver secret bile and pancreas secrete pancreatic juice and intestinal enzymes work upon it by converting complex molecules into simpler molecules. It breaks carbohydrates into glucose, fat into fatty acids and protein into amino acids. Waste material then send to large intestine for absorption of excess water. Then it send to rectum and waste thrown out through **** and digestion complete. | |

differnce between systolic and daistolic |
||
| Answer» | SYSTOLE | DIASTOLE | \t\t\tSystole is the contraction phase of the cardiac cycle of the heart.Diastole is the relaxation phase of the cardiac cycle of the heart.In systole stage, when the heart contracts, it pumps blood from the heart Chambers into the aorta and a pulmonary artery.In Diastole stage, when the heart relaxes, it allows the heart chambers to be filled with blood from venacava and pulmonary veins.The blood pressure of the systole stage is high.The blood pressure of the diastolic stage is low.The systolic pressure for a normal person is 120.The diastolic pressure for a normal person is 80.The systolic pressure undergoes considerable fluctuations at different conditions like the extent of work done by heart, the force at which the heart is working, etc.The diastolic pressure undergoes much less fluctuation in health and remains within a limited range. The increase in diastolic pressure indicates that the heart is approaching towards failure.\t|

Difference between phototropisim and photoperodisim |
| Answer» Photoperiodism is the developmental responses of plants to the relative lengths of the light and dark periods.Phototropism is\xa0a phenomenon where the growth of a plant is determined by\xa0the direction of\xa0the light source. Growth towards a light source is a positive phototropism, while growth away from light is called negative phototropism.In phototropism, the direction of the plant growth is influenced. There is no direction involved in photoperiodism.Phototropism is enabled by auxins. Phototropism in plants\xa0is regulated\xa0by receptors such as\xa0phototropins, phytochromes,\xa0cryptochromes etc.Several hormones are involved in photoperiodism. Many flowering plants use a photoreceptor protein, such as phytochrome or cryptochrome, to sense seasonal changes in day length. | |

|
Answer» There are many types of digestive enzyms in our body,which helps us in various functions.Function of certain enzymes are defined here:1.Saliva :Saliva secreted by salivary glands contains an enzyme salivary amylase that breaks down complex molecule starch into simple sugar.And,helps in thorough mixing of food in our mouth ,which makes the food easy to travel through alimentry Canal.2.Pepsin :An enzyme pepsin is present in the wall of stomach .It activates only in the presence of hydrichloric acid and start work.It helps in digesting protiens into amino acids. The muscular walls of the stomach help in mixing the food throughly with more digestive juices and release hydrochloric acid a protien digesting enzyme called pepsin and mucus |

Explain the chemical properties of acid |
| Answer» Chemical properties of acid:\tAcids change the colour of litmus from blue to red.\tThey convert the colour of Methyl Orange from Orange/Yellow to Pink.\tAcids turn the pink colour of Phenolphthalein to colourless.\tSome Acids are highly corrosive in nature which means that they corrode or rust metals.\tAcids tend to evolve hydrogen gas whilst reacting with an active metal such as Zn, Mg, etc.\tThey produce H+ ions when mixed with water.\tAcids lose their acidity when mixed with a base.\tWhen equal amounts of acid and base are combined the process of neutralization occurs and salt and water is formed, The pH value of acid is from 0-6.\tAcids react with carbonates and hydrogen carbonates to form a salt, water and carbon dioxide gas.\tExtremely active metals such as Potassium (K), Calcium (Ca), Sodium (Na), etc tend to explode when combined with acids.\tWeak Acids like Carbonic Acid doesn’t act with any metal at all.\tNitric Acids doesn’t usually exhibit acidic properties, it exhibits oxidizing properties instead.\tMetals that generally react with dilute acid to form salt and hydrogen are the metals which lie above hydrogen in the metal activity series. Acids form a salt, water and sulphur dioxide while reacting with sulphites and bisulphites.\tAcids and metal sulphides form salt and hydrogen sulphide. | |
