What are the properties of ionic compounds |
|
Answer» Thanks for the answer Properties of ionic compounds are as follows.\tIonic compounds are solids and hard due to the strong attracting force between the positive and negative ions. These compounds are generally brittle and break into pieces on application of pressure.\tIonic compounds have high melting and boiling points because a application of significant amount of energy can break the strong inter-ionic attraction.\tIonic compounds are soluble in water but insoluble in solvents like kerosene, petrol, etc.\tConduction of electricity through a solution is possible when there is movement of charged particles. Ionic compounds in the solid state do not conduct electricity because movement of ions in the solid is not possible due to their rigid structure.\tA solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution. Ionic compounds conduct electricity in the molten state as in the molten state the electrostatic forces of attraction between the oppositely charged ions overcome due to the heat. Thus, the ions move freely and conduct electricity. |

Diagram of stomatal apparatus |
| Answer» The minute pores present in the epidermis of leaves are called stomata. A stoma is composed of two guard cells; which are bean-shaped. The guard cells are dumbbell-shaped in grasses. The outer wall of guard cells is thin and the inner walls are highly thickened. Chloroplast is present in the guard cells. The guard cells regulate the opening and closing of stomata. A few specialized epidermal cells may be present near the guard cells. These specialized cells are called subsidiary cells. The stomatal aperture, guard cells and subsidiary cells together make the stomatal apparatus. Transpiration and exchange of gases are regulated by stomata. | |

Male reproductiv organ exaplan |
| Answer» The male reproductive system of human beings consists of a pair of testis, accessory glands and a system of ducts.Testis are male reproductive organs and produces spermotozoa or sperms and also secretes male *** hormone Testosterone.Inside each testis several lobules are present. Each lobule has several tubules called seminiferous tubules.Germinal epithelial cells in the seminiferous tubules undergo meiotic division to produce spores.The accessory glands include one prostrate gland and two cowper glands. Secretion of these glands produce semen.The duct system consists of vas efferentia. They collect spermatozoa from seminiferous tubules.Vasefferentia continue as epididymis where sperms are stored temporarily.From epididymis sperms moved into tubule called vas deferens and then into urethra. | |

describe the magnetic field produced by current carrying solenoid. |
| Answer» The solenoid is a long cylindrical coil of wire consisting of a large no. of turns bound together very tightly. Solenoid is a coil of a number of turns of insulated copper wire closely wrapped in shape of a cylinder. Solenoid behaves like North Pole and the other end behaves like the South Pole. Magnetic field lines inside the solenoid are in the form of parallel straight lines. This means that the field is same at all the points inside the solenoid. When soft iron rod is placed inside the solenoid, it behaves like an electro magnet. The use of soft iron as core in the solenoid produces the strongest magnetism. | |
