What is ionic compound? and their properties. |
| Answer» Ionic compounds are those compounds in which ions in a lattice are held together by ionic bonds. Generally in ionic compounds, cations are metal ions and anions are nonmetals. Anions can also be a polyatomic anion. These ions are held together by electrostatic forces of attraction.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. | |

What is double circulation system and why this is necessary |
|
Answer» In double circulation blood goes twice in the heart during each cycle. Once it carries oxygenated blood from the heart to the rest of the body parts and again it carries de oxygenated blood from the body to the heart.It is necessary to keep the oxygenated and de oxygenated blood from mixing which helps in more efficient supply of blood and heps the mammals and birds to regulate their body temperature Double circulation essential because it will prevent micing of pure and impure blood During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature. In vertebrates blood goes twice during each cycle .This is called double circulation. Why it is necessary |

Why do we need to balanced chemical equation |
|
Answer» According to the law of conservation of mass , when a chemical reaction occurs, the mass of the products should be equal to the mass of the reactants. Therefore, the amount of the atoms in each element does not change in the chemical reaction. As a result, the chemical equation that shows the chemical reaction needs to be balanced. A balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side. We should balance the eq. because we need to stable the atoms or we can say to stable the elements or compound . We need to do so to also make it easily understand the quantity if we do a practical. Yes we should balance a chemical equation in order to satisfy law of conservation of mass |

Write four properties of concave and convex mirror |
| Answer» Properties of the image formed by a convex mirror :1) The image is always virtual and erect.2) The image is highly diminished or point sized.3) It is always formed between F and P.4) The object and image are on opposite sides of mirror.CONCAVE MIRRORS;1. They always produce real and inverted images except when an object is placed between the mirror pole and the focus which gives erect virtual images. (for real objects)2. They produce magnified, diminished and same size images. 3.A parallel beam of incident light is concentrated on its focus and thus such a mirror is called a convergent mirror. Also a light source placed at the focus produces a parallel light beam. 4.Sign convention: The focal length and radius of curvature are taken as negative. | |
