Answer» tion:Up to now, we have presented chemical reactions as a topic, but we have not discussed how the products of a chemical reaction can be predicted. Here we will begin our study of certain types of chemical reactions that allow us to predict what the products of the reaction will be.A single-replacement reaction is a chemical reaction in which one element is substituted for another element in a compound, generating a new element and a new compound as products. For example,2 HCl(aq) + Zn(s) → ZnCl2(aq) + H2(g)is an example of a single-replacement reaction. The hydrogen atoms in HCl are replaced by Zn atoms, and in the process a new element—hydrogen—is FORMED. Another example of a single-replacement reaction is2 NaCl(aq) + F2(g) → 2 NAF(s) + Cl2(g)Here the negatively charged ion changes from chloride to fluoride. A typical characteristic of a single-replacement reaction is that there is one element as a reactant and another element as a product.Not all proposed single-replacement reactions will occur between two given reactants. This is most easily demonstrated with fluorine, chlorine, bromine, and iodine. Collectively, these elements are called the halogens and are in the next-to-last column.plz follow me and add this as BRAINLY list. |

A bullet moving with a velocity of 800 m/s passes through two plates of widths d, and d2. In passing through each of them, it loses a velocity of 200 m/s. If d, is 7 cm then, if both the plates offer same then continues at constant speed for time t and then decelerates at the rate f/2 to come to rest. If the total distance traversed is 5 s, then, find the ratio d1/d2 |

Explain dispersion of white light by a glass prism ? |
|
Answer» When WHITE light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, BLUE, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as DISPERSION. Definition: Dispersion of white light is defined as splitting of white light into seven constituent colours when passed through the prism. White light dispersion occurs because, as they pass through a prism, different colours of light bend through different angles with respect to the incident RAY. The red light bends the least while the violet bends most as shown below. |

Answer» The FOCAL length of the lens = 0.5 mExplanation:The capability of lens to bend the light is termed as the POWER of lens. ALSO the greater the power the greater the refraction of light.The power of a lens is also defined as the INVERSE of the focal length.Mathematically,Power\ of\ a\ lens\ = \frac{1}{f}Power of a lens = f1 Where,f = focal length of the lens which is MEASURED in meters.Power of a lens is measured in Dioptres (D).Now from the question,Power of the lens = +2 D∴ Power\ of\ a\ lens\ = \frac{1}{f}Power of a lens = f1 2 = \frac{1}{f}2= f1 ⇒ f = 0.5 mExplanation:you solve queston |
