Write the advantages and disadvantages of Mendeleev periodic table |
| Answer» Advantages:1. Grouping of elements. He generalized the study of the elements then known to a study of mere 8 groups.2. Gaps for undiscovered elements. Mendeleev left some gaps in his periodic table. These gaps were left for subsequent inclusion of elements not known at that time. He correctly thought that such elements would be discovered later.3. Prediction of properties of undiscovered elements. He predicted the properties of then unknown elements om the basis of properties of elements lying adjacent to the vacant slots.4. Incorrect masses corrected. He was able to correct the values of atomic mass of elements like gold and platinum by placing these elements strictly on the bases of similarities in their properties.Disadvantages:1. Anomalous pairs: Argon with atomic mass 39.9 precedes potassium with atomic mass 39.1.Cobalt with atomic mass 58.9 precedes nickel with atomic mass 58.6.Tellurium with atomic mass 127.6 precedes iodine with atomic mass 126.9.2. Position of isotopes: According to Mendeleev\'s periodic law, isotopes of an element must be given separate places in the periodic table since they have different atomic masses. But they were not assigned separate places.3.Grouping of chemically dissimilar elements: Elements such as copper and silver bear no resemblance to alkali metals but they have placed in separate groups.4.Separation of chemically similar elements: Elements that are chemically similar, such as gold and platinum have been placed in separate groups.5.Electron arrangement: It does not explain the electron arrangement of elements.6. Position of Hydrogen: It was not given in a fixed position. | |

What are the bio-product of fertilizer industries?how do they affect the environment? |
| Answer» The by products of the fertilizer industries are :-\xa0a) Gases- SO2, NOx, CO, CO2, H2S\xa0b) Solids- Pyrite ashes, Calcium Carbonate, sand and plastic bag.\xa0Effect on Environment\xa0The majority of the gaseous by products like carbon dioxide, methane are green house gases which contribute to global warming. Rest of the gases like sulphur dioxide and nitrous oxide are air pollutants and lead to acid rain. These gaseous by products cause breathing and respiratory problem. The solid waste and waste water discharges into the water body. When these wastes are discharged in the water body they increase the nutrient content of the water and cause algal bloom (increase in number of algae). Due to algal bloom, algae forms a layer on the surface of the water and hence the oxygen does not reach the water body and all the fishes and water animals are killed. | |

Mendal 3 Laws Of inheritance in easy language |
| Answer» The three laws given by Mendel are:i. Law of dominance - According to this law, when a cross is made between two homozygous individuals, only one of the two characters of the pair (dominant) appears in the F1 generation. There is the appearance of both the characters in F2 generation.ii. Law of segregation - This law states that the characteristics of an organism are determined by the internal factors which occur in pairs. Only one of a pair of such factors can be present in a single gamete.iii. Law of independent assortment - This law states that in the inheritance of more than one pair of traits in a cross simultaneously, the factors responsible for each pair of traits are distributed independently to the gametes. | |

Activity 1.7 electrolysis of water |
|
Answer» Activity:Take a glass jar fitted with 2carbon electrodes.one acts as a cathode the other acts as an anode.Two test tubes are inverted on the carbon rods to collect some gas.They are connected to a6V battery.Now fill the glass jar with 100 ml of acidified water.Now thermal decomposition takes place and releases twice the volume of hydrogen gas and one volume of oxygen gas in the form of bubbles in the test tube.Now carefully take out hydrogen containing test tube and take it near the candle it burns very brightly.In the ratio of 2:1 volumes of hydrogen and oxygen are collected respectively. Very easy. Composition of water 2 molecules of hydrogen and one molecule of oxygen. That\'s why 2:1 ratio. |
