Write short notes on Rancidity |
| Answer» Rancidity is simply defined as the oxidation of fats and oils. These substances smell and taste unpleasant after decaying. We can prevent it by putting the substance into air tight container or pack it with inert gas which won\'t react with the fats and decay them. Also adding of antioxidants is also advised | |

Write short notes on corrosion |
| Answer» Corossion is the chemical reaction in which the surface of the metal reacts with moisture of the atmosphere to form a powdery substance which easily falls off from its surface and hence it exposes the inner part of the metal for further corrosion thus destroying the metal . It destroys buildings, monuments etc. | |

About digestive system in human being |
| Answer» The digestion of human include five basic steps:- 1) Ingestion:- taking in of nutrient2) Digestion:- Process through which complex food substances are broken down into simpler food substances.3) Absorption:- This occurs in small intestine where important food nutrients are absorbed and transported through body fluid or blood to various body parts.4) Assimilation:- Further, water and water soluble nutrients are absorbed in the Large intestine and sent to the body cells.5) Egestion:- The undigested food substances are expelled out of the body.Our digestive system also known as Alimentary canal contains:-1] Mouth:- An open slit through which the food is ingested.2] Buccal cavity:- It contains Tongue for swallowing the food and teeth to break the food particles into smaller and soluble form. Our saliva generated by the salivary gland help in lubricating the food so that it doesn\'t choke in the oesophagus.3] Oesophagus:- also known as food pipe helps in pushing the food into the stomach by a contraction and relaxation movement known as Peristalsis.4]Stomach:- The food is sent here so that it can be churned well. Our stomach is a J - shaped organ on the left of the abdomen. It has HCl, Pepsin and Mucus in it.5]small intestine:- Th food is sent here to absorb all the important nutrient like Carbohydrates, Proteins and fats into its simpler substance (i.e Glucose, Amino acids and Fatty acids).6] Large intestine:- the water and water soluble nutrients are absorbed in the large intestine and the undigested food are expelled out of the body through **** in the form of Faeces. | |

What is a balanced chemical equation??? Why should chemical equation be balanced |
|
Answer» a blanced equation is a eqaution in which no of atom in reactant and product are equalA chemical equation should be balanced to satisfy the law of conservation of mass Balanced chemical equations are those equations in which the number of atoms of elements are equal in both of reactants and productAnd we should balance a chemical equation in order to satisfy the law of conservation of mass The reaction in which the number of atoms of each element is equal on the reactant side and product side is called balanced equation.Chemical reaction should be balanced because only a balanced equation tells us the relative quantities of different reactants and products involved in the reaction. |

How can we make chemical equation more informative? |
| Answer» We can mention the catalyst which are helping the reaction. Also, we can mention the formation of gas and precipitate by indicating upward arrow and downward arrow respectively. Again, the atmospheric pressure or temperature can be mentioned. Also, the state of the compound can be mentioned which are Aqueous, gas, solid or liquid. | |

Difference between potential difference and electric potential |
| Answer» Potential difference: Potential difference is the difference in electric potential energy between two points. It is the amount of work done in moving a unit positive charge from one point to another point in an electric field. This is measured in volt. V = E.dElectric potential: An electric potential at a point in an electric field is the work done by the electric field in moving a unit positive charge from infinity to that point. This is also measured in volt. V = kQ/r | |

Why megnisium ribbon is cleaned before burning |
| Answer» Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. | |

What do you mean by a circuit in series |
| Answer» A series circuit is a closed circuit in which the current follows one path, as opposed to a parallel circuit where the circuit is divided into two or more paths. In a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load. Ohm\'s law applies where the total resistance is equal to the sum of the individual resistances: Rt= R1+ R2+ ……+ RN. The total capacitance of capacitors in series is equal to the sum of the reciprocals of their individual capacitances: Rt= R1+ R2+ ……+ RN . Unlike a parallel circuit, a series circuit will not function if one part is broken; that is, the current will not flow through the rest of the circuit. | |
