Formation of CaCl2 ionic bond? |
| Answer» Atomic number of calcium is 20.Electronic configuration of calcium: 2, 8, 8, 2Number of electrons in outermost orbit = 2Valence electron = 2Valence electrons of chlorine = 7Calcium loses two electrons in order to achieve stable electronic configuration. Each of the two chlorine atoms on the other hand gains one electron losing from calcium to get stability. By losing of two electrons calcium gets two positive charges over it. Each of the chlorine atoms gets one positive charge over it. | |

Answer» Artries1.they are thick.2.they contain oxygenated blood (except pulmonary artrey)3.narrow lumen.4.more blood pressure.5. Valves are absentVeins1.they are thin.2.they have broder lumen.3.they have less blood pressure.4.they have deoxygenated blood (except pulmonary vein)5.valves are present. ARTERIES-They are the blood vessels which carry blood away from the heart to various organs of the body.They have thick and the elastic walls because the blood emerges from the heart under high pressure.They carry oxygenated blood accept pulmonary artery which carries dioxyginated blood.VEINS-They are the blood vessels which collect blood from different organs and bring it back to the heart.They have thin walls because the movement of blood is no longer under pressure, instead have valves.They use to carry dioxyginated blood with the exeption in pulmonary veins which carry oxygenated blood. |

Why do some fruits have one seed other have two seeds and some have a number of seeds? |
| Answer» Seeds are generally formed by the maturation of ovule after fertilization in flowering plants. In some plants fruit is formed from a single flower and bears a single ovule. This type of fruit will bear single seed like mango, cherry, plum, peach etc. Some fruits are formed from single flower with multiple ovules. This gives rise to several seeds like tomato, oranges, watermelon, cucumber, passion fruit, kiwi etc. Fruits like pea, peanut, beans etc. are formed by aggregation of numerous flowers with numerous ovules. They produce several seeds. | |
