What happen when carbon dioxide gas is passed through quicklime? |
|
Answer» When Carbon dioxide gas is passed through lime water it turns milky due to formation of insoluble calcium carbonate ( white precipitate).Ca(OH)2+ CO2→ CaCO3 + H2O ( White precipitate)On passing excess CO2 the white precipitate disappeares as soluble calcium\u200b bicarbonate is formed.CaCO3 + CO2 + H2O → Ca(HCO3)2 (excess) (Soluble) I think it will release Hydrogen gas |

Production of washing soda |
| Answer» In the following three steps, washing soda is prepared from sodium chloride or common salt.Firstly, a cold and concentrated sodium chloride solution is reacted with ammonia and carbon dioxide to obtain sodium hydrogen carbonate.The sodium hydrogen carbonate is slightly soluble in water, so it precipitates out as solid.NaCl +NH3\xa0+CO2\xa0+H2O → NaHCO3\xa0+NH4ClSecondly, now sodium hydrogen carbonate is separated by filtration, dried and heated. On heating sodium hydrogen carbonate decomposes to form sodium carbonate. This anhydrous sodium carbonate is known as soda ash.2NaHCO3\xa0→ Na2CO3\xa0+H2O +CO2 Soda ashThe preparation of Sodium Carbonate is also known as Solvay process. But before that calcium carbonate (limestone) was heated to release carbon dioxide.Thirdly, anhydrous sodium carbonate or soda ash is dissolved in water and recrystallised to get washing soda crystals containing 10 molecules of water of crystallisation.Na2CO3 + 10H2O → Na2CO3.10H2O Washing Soda | |

How do organism produce means |
|
Answer» It means what are the factors by which organism produce Organisms produce by the process of reproduction Reproduction is the process by which a living organism is able to produce new individuals of its own kind. Unlike other life processes such as nutrition, respiration, etc., it is not essential to, maintain the life of an individual organism. But it is important for the existence and continuity of the species. Reproduction involves the creation of DNA copy and additional cellular apparatus by the cell involved in the process. The process of DNA copying leads to variations. This inbuilt tendency for variations during reproduction is the basis for evolution. |

what is lipase enzymes |
| Answer» Lipase enzyme breaks down dietary fats into smaller molecules known as glycerol and fatty acids. A little quantity of lipase, known as gastric lipase is produced by the cells of the stomach. This enzyme mainly digests fat present in the food. The pancreas is the primary source of lipase in the digestive tract, which produces pancreatic lipase which acts in the small intestine. The bile produced in the liver and liberated in the intestine transform dietary fat to small fat globules.\xa0 | |

Why the carbon always form covalent bond not ionic bond |
|
Answer» Because it is not easy for nucleus to hold 4 more electron in its small size shell and also cannot lose 4 electron to make 4 positive charge There r four valence electrons in a carbon atom. Now,if it have to form an ionic bond it must lose or gain four electrons.it is not possible to lose four electrons as carbon atom is very small and electrons are strongly held by nucleus. It also not possible to add as many as four electrons to a carbon atom Sry bhai!! Voice recognition Four Valence Electrons and the iten idle form bonds by using organic electronics if I lose |

Write the functions of---Cytokinins,abscisic acid,auxin |
| Answer» Cytoknins are a large group of proteins, peptides or glycoproteins that are secreted by specific cells of immune system. Cytokines are a category of signaling molecules that mediate and regulate immunity, inflammation and hematopoiesis.☺️☺️☺️☺️☺️☺️☺️Abscisic acid (ABA) is a plant hormone. ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure. It is especially important for plants in the response to environmental stresses, including drought, soil salinity, cold tolerance, freezing tolerance, heat stress and heavy metal ion tolerance.☺️☺️☺️☺️☺️☺️☺️☺️The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant is one of the main places that auxin is produced. This makes sense because the apical meristem is also the location that all the other parts of a plant grow from - the stem, leaves, and flowers.☺️☺️☺️☺️☺️☺️☺️☺️☺️☺️ | |

Sketch the break down of glucose by various pathways. |
| Answer» In aerobic respirationGlucose. + Pyruvate - water + carbon dioxide + 38 atpIn anaerobic respirationGlucose _glycolysis(in cytoplasm ) pyruvate - C2H5OH +co2 + 2 atpIn aerobic respiration 1 molecule of glucose is breakdown in pyruvic acid 2 molecules by glycolysis ( in cytoplasm) then a lot of energy is released with CO2 and H2O. Energy is stored in mitochondria of the cell whereas in anaerobic respiration 1 molecule of glucose is breakdown into pyruvate 2 molecules in absence of O2 ( muscle tissue) or yeast ( an organism) gives ethanol Co2 and atp.In muscles lactic acid is formed which causes cramps.It is stored in muscle tissues in human body | |
