Write a note on the acidity of acetylene. |
| Answer» <p>The C-H bonding electrons in acetylene are contained in ansphybrid orbital. In the conjugate base of acetylene, acetylide carbanion, thissphybrid orbital holds an unshared electron pair. Thesphybrid orbital holding this unshared electron pair has greaterscharacter compared to thesp2orsp3orbitals holding an electron pair in analogous vinylic or aliphatic carbanions. This allows the unshared electron pair to be held at lower energy, which allows acetylene to have measurable, though still very weak, acidity.</p> | |

Questions-1) How are the Acid salts are formed?2) Which measures are taken to decrease acidity in body? |
| Answer» <p>1.When weakacidsand bases react, the relative strength of the conjugatedacid-base pair in thesaltdetermines the pH of its solutions. Thesalt, or its solution, soformedcan beacidic, neutral or basic. Asalt formedbetween a strongacidand a weak base is anacid salt, for example NH4Cl.</p><p>2.For decreasing acidity we take Antacid.Because antacid contains base which react with acid present in our body and form salt and water and it help to get relief from acidity.</p> | |

a. What is the difference in the atomicmodels of Thomson and Rutherford? |
| Answer» <p>1. On one hand, Thomson's Model emphasised on the uniform distribution of mass and within an atom, Rutherford's model gave the concept of the mass being concentrated in a centrally located region, called nucleus.</p><p>2. Thomson's Model depicted electrons as being stationary and embedded within the positive sphere. Rutherford stated that Electrons move around the nucleus and are in motion.</p><p>3. Where on one hand Thomson's model was relatively stable, Rutherford proposed a very unstable model of an atom, as electrons would radiate energy when in motion, and ultimately fall into the nucleus.</p> | |

the maximum permissible voltage drop in a power industrial circuit should not be more than of the declared supply voltage |
| Answer» <p>Voltage drops occur throughout the distribution network. However, it is necessary to regulate the voltage in order to ensure that these drops stay within a permissible range. High voltage drops, below the permissible level, can have many negative consequences. These result in an increase in the system maintenance cost and a decrease in the safety and performance of the network. Operating electrical equipment below its rated voltage can be dangerous as well as reducing the expected lifetime of the equipment. When inductive loads are operated below their rated voltage, they tend to overheat and consume more power. Resistive loads which are operated at a too low voltage will not be able to produce the desired output. Reducing the voltage by 10% will reduce the power output by 19%, since power output correlates to the voltage squared. A reduction in the network voltage can cause lights to flicker when other appliances are turned on.</p> | |

what is vector quantity |
| Answer» <p>In mathematics, physics, and engineering, a Euclidean vector is a geometric object that has magnitude and direction. Vectors can be added to other vectors according to vector algebra. A Euclidean vector is frequently represented by a line segment with a definite direction, or graphically as an arrow, connecting an initial point A with a terminal point B, and denoted by \overrightarrow{AB}.</p> | |

what is vector quantity withexample |
| Answer» <p>A vector refers to any quantity that needs a magnitude and a direction in order to fully describe the quantity. e.g., displacement</p><p>Explanation:By magnitude, we mean the size of the quantity, such as length or strength. By direction, we mean where the vector is pointing or where it is being directed, such as left or right, north, south, east, or west, or even up or down. When you use your global positioning system (GPS) in your car to help you get to your destination, the GPS unit will give you two pieces of information, such as drive 300 feet and then turn left. That is an example of a vector.</p> | |
