Write the reaction of hydrogen ion with water. Or how hydronium ion is formed? |
| Answer» A\xa0hydrogen ion is formed\xa0when a\xa0hydrogen\xa0atom loses an electron and therefore becomes positively charged (it has a charge of +1). A\xa0hydrogen\xa0atom is therefore often referred to as just a proton, as it is left with only one proton and no electrons, as a\xa0H\xa0atom only has one of each.\xa0It can be\xa0formed\xa0when an acid is present in\xa0water\xa0or simply in pure\xa0water. It\'s chemical formula is H3O+. ... As H+\xa0ions are formed, they bond with H2O molecules in the solution to\xa0form\xa0H3O+ (the\xa0hydronium ion). This is because\xa0hydrogen ions\xa0do not exist in aqueous solutions, but take the\xa0form\xa0of the\xa0hydronium ion, H3O+. | |

Why metals are sonorous? |
|
Answer» When we beat a metal , its atoms start vibrating Hence producing sounds Meaning of sonorous • capable of giving a deep, resonant sound.• makes a ringing sound when hit.Electron bondings in metals is highly delocalized ( due to very low Electronegativity).This means that when hit, the electron clouds move easily - there is very little energy dissipiated.This allows the incoming kinetic energy to be easily propagated as a form of disequilibrium (wave)Not all metals have this physical property.... |

Tap water conduct electricity whenever this style water does not |
| Answer» Tap water\xa0contains dissolved salts in it. These salts dissociate into ions\xa0when electricity\xa0passed through it which\xa0are\xa0responsible for the\xa0electrical\xa0conductivity of\xa0tap water. But distilled\xa0water does not\xa0contain any dissolved salts, so it\xa0does not conduct electricity.\xa0Tap water conducts electricity\xa0because it contains dissolved salts and minerals which ionise\xa0in water. The presence of these ions makes\xa0tap water\xa0good conductors of\xa0electricity. Therefore, due to the lack of ions\xa0in\xa0the liquid, distilled\xa0water does\xa0not\xa0conduct electricity. | |

What types of tissues |
| Answer» Animal tissues are basically grouped into four types:\tConnective Tissue\tMuscle Tissue\tNervous Tissue\tEpithelial TissueThe classification of plant tissues\tEpidermis Tissues – cells\xa0formed from the outer most surface of the leaves.\tVascular Tissues –\xa0involved in\xa0transporting fluid and nutrients internally.\tGround Tissue – involved in\xa0producing nutrients by photosynthesis and preserve nutrients.\tMeristematic tissues.\tPermanent tissues. | |

what ere amphoteric oxides |
| Answer» Amphoteric oxides and hydroxides share the property of being able to behave as acids. An amphoteric oxide is one that can act as either an acid or a base. Generally, non-metallic oxides are acidic and metallic oxides are basic. Metallic oxides, which show the basic as well as acidic nature, are known as amphoteric oxides. Elements that form amphoteric oxides have some characteristics of metals and some of the non-metals. | |

cardiac cycle |
| Answer» The cardiac cycle is the performance of the human heart from the ending of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, dubbed systole. | |

What is atmospheric oxide ?Give Example?? |
|
Answer» It\'s amphoteric not atmospheric Example is zinc oxide Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides. Such metallic oxides react with acids as well as base to produce salt and water. Examples of Amphoteric oxides are aluminium oxide and zinc oxide. Bro, it is a oxide that can react with both - acid and base to from salt and hydrogen |

Explain the phenomenon biological magnification |
| Answer» Biological magnification refers to the process of increase in the concentration of a toxic chemical with increasing trophic level in a food chain. Harmful or poisonous substance such as DDT sprinkled to kill pests on plants enter the food chain. The plants absorb these harmful chemicals from soil along with water and minerals. They enter the food chain at producer level and then transfers to the next trophic level. The tertiary consumers get more higher levels of these chemicals. | |

Why copper is not react with Hcl ?? |
|
Answer» Because copper is less reactive than Hydrogen , so it is unable to displace Hydrogen from HCl Hence no reaction occurs Because Copper is less reactive than hydrogen. So, it can\'t react with hydrogen Generally the reaction of a metal with an acid is written as\xa0\xa0Metal + acid ------> Metal salt + hydrogen gasNow this reaction is not true for all the metals. Only those metals which are more reactive than hydrogen will liberate hydrogen from the acid and form the corresponding metal salt. These metals are placed above hydrogen in the reactivity series. As copper is less reactive than hydrogen, therefore it will not liberate hydrogen gas from the acids like HCl, HNO3, H2SO4\xa0etc.\xa0But sulphuric acid is a strong oxidising agent, therefore it will oxidise copper metal to Cu2+\xa0ion. However, no hydrogen gas will be formed, only copper metal will be oxidised here. On the other hand, HCl is not that strong oxidising agent, in fact its use as an oxidising agent is not too well known. Hence it does not react with copper metal at all. |

How do plant produce seeds reproduce |
| Answer» A flower can either have the male or female part or both the parts. Flowers in plants carry out the reproductive functions in plants when both the male and female gametes are fused to produce the seeds which bear the fruit. These seeds germinate to produce new plant structures.Plants reproduce through two modes of reproduction:\tAsexual mode of reproduction\xa0– New plants arise from vegetative parts\tSexual mode of reproduction\xa0– New parts arise from reproductive parts of the plant | |

What are plant hormones? Explain. |
|
Answer» Plant hormones are chemical organic substances that help to bring about control and coordination in plants Plant hormones are simple organic substances transported through xylem, phloem or by diffusion. They are produced in one part of the plant and transported to the other. No specific organs are involved in the synthesis of the plant hormones.Examples: Auxins, cytokinins, ethylene, gibberellins.\xa0 Plant hormones are chemicals plants use for communication, coordination, and development between their many cells. Like animals, plants rely on these chemical signals to direct the expression of DNA and the operations of the cell |

How does amaeba gets food |
| Answer» Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. The remaining undigested material is moved to the surface of the cell and thrown out.\xa0The complete phagocytosis process includes intake, digestion , absorption, assimilation, and egestion process.\xa0 | |
| 1533. |
What are heterocrine glands ? Give one example . |
| Answer» Heterocrine glands are those glands that possess both exocrine ( which release chemical substances through ducts) as well as endocrine parts ( which release chemical substances directly into bloodstream or body parts).Two examples of heterocrine glands are-1) Pancreas ( as they perform both exocrine and endocrine function)They release insulin and glucagon into bloodstream ( endocrine function) and release digestive enzymes through ducts in the digestive tract ( exocrine function).2) Ovary :\xa0It releases steroid hormones ( estrogen and progesteron) into bloodstream and also performs exocrine function by producing ova into duct.\xa0 | |
