Hii friendexplain :---- Rutherford scattering experiment |
|
Answer» Answer: Rutherford's alpha PARTICLE scattering experiment changed the way we think of atoms. Before the experiment the best MODEL of the atom was known as the Thomson or "plum pudding" model. The atom was believed to consist of a positive material "pudding" with negative "plums" distributed throughout. Rutherford directed beams of alpha particles (which are the nuclei of helium atoms and hence positively charged) at thin gold foil to test this model and noted how the alpha particles scattered from the foil. Rutherford made 3 observations: •Most of the FAST, highly charged alpha particles went whizzing straight through undeflected. This was the expected result for all of the particles if the plum pudding model was correct. •Some of the alpha particles were deflected back through large angles. This was not expected. •A very small number of alpha particles were deflected backwards! This was definitely not as expected. Rutherford later remarked "It was as INCREDIBLE as if you fired a 15-inch shell at a piece of tissue paper and it came back at you!" To explain these results a new model of the atom was needed. In this model the positive material is concentrated in a small but massive (lot of mass - not size) region called the nucleus. The negative particles (electrons) must be AROUND the outside preventing one atom from trespassing on its neighbours space to complete this model. I hope this answers your question ! |

Iodine solution is used to test the presence of (a) starch (b) fats (c) proteins (d) vitamin |
|
Answer» Answer: Answer is (a). the iodine TEST is used to test the presence of starch. starch turns into an itense 'blue black' colour upon addition of aqueous solution of triiodine anion, due to the FORMATION of an intermolecular charge TRANSFER complex. in the absence of starch the BROWN colour of aqueous solution remains. hope you will understand. |

What is Zeff effective.....?? |
|
Answer» ★The EFFECTIVE nuclear charge (often symbolized as Zeff or Z*) is the net positive charge experienced by an electron in a multi-electron atom. ★ The term “effective” is used because the shielding effect of NEGATIVELY charged electrons prevents higher ORBITAL electrons from EXPERIENCING the FULL nuclear charge. |

Explain radicals in brief. |
|
Answer» Answer: Radicals are usually formed when a single covalent bond breaks to leave an unpaired electron on each of the two species CREATED by the bond breaking: this is called homolysis. Homolysis is shown in the diagram below, where a single electron moves from the bond to each atom, producing radicals A. and B.. homolysis Dots are placed on radical species to show that they possess a single, unpaired electron. Cleaving a CHEMICAL bond requires energy to be input, such as heat or light. In general, radicals are highly reactive and form new bonds again very quickly. A radical may be electrically neutral, positively charged (radical CATION) or negatively charged (radical anion). Examples of Radicals 1. The chlorine molecule Cl2 undergoes homolysis in ultraviolet light to form two Cl. radicals. These are electrically neutral and highly reactive. 2. BROMINE water is used in organic chemistry as a test to detect ALKENES. Bromine water is brown-orange. When added to alkenes, it decolorizes. The reason for this is that the brown-orange bromine dissolved in water undergoes homolysis and reacts with alkenes. This is an example of an addition reaction. Br2 + H2O + CH2=CH2 → Br-CH2-CH2OH + HBr 3. When tobacco is burned to produce cigarette smoke, the smoke contains a large number of free radical molecules. These free radicals are highly reactive, and when tobacco smoke is inhaled, react with lung tissues. This results in inactivation of alpha 1-antitrypsin, promoting the development of the fatal lung disease emphysema. Explanation: |

Give short notes on Charles law. |
|
Answer» ➡️Charles' LAW states that for a MASS of gas held at a FIXED pressure, the volume of the gas is directly proportional to the absolute temperature of the gas. ▪Charles' Law Formula and Explanation➡️It states that the volume of a fixed mass of a gas is directly proportional to the temperature. This law applies to ideal gases held at a constant pressure, where only the volume and temperature are ALLOWED to change. Charles' Law is EXPRESSED as: Vi/Ti = Vf/Tf. |

Why the rocket propulsion |
|
Answer» Answer: Hey..!! When a plane flies at steady speed, the forward THRUST MADE by the engines is EQUAL to the air resistance (drag) pulling back. ... With a rocket, thrust from the engines pushes upward while weight and drag TRY to pull it back down. When the rocket accelerates upward, the thrust is greater than the combined lift and drag. ===================== Hope it helps mark it as the brain list answer and follow me |

How opening window prevents us from indoor air pollution |
|
Answer» Answer: it can allow TRAVEL particulates Explanation: in our ATMOSPHERE we have dust particles called particulates so when open the windows the particulates present in our home will go outside because the air molecules are unstable and USUALLY move AROUND. so if we open our windows they is a high chance that the particulates go outside thus decreasing the indoor AIR pollution |
