Name some industries family to you make a list of products of tin from them and use them in our daily life explain how the growing of industrial act is responsible for the depletion of water table

Answer»

i) Increased population : Demand for water has been increased by the increased population. As the number of humans INCREASES, the consumption of water also increases.(ii) Increasing industries : All industries need water. As the number of human population increase, the number of industries is also increased which definitely increases the consumption of water.(iii) Lack of water conservation techniques : Main source of water on earth and for the underground water is rain. The water of the rain, if CONSERVED can increase the groundwater LEVEL. But this is not due to lack of water conservative techniques.(iv) Agricultural activities : INDIA is a country which depends on agriculture. The land used for cultivation has increased. So, the consumption of water for agriculture has increased. Irregular RAINFALL has increased the consumption of groundwater. This has increased the depletion of groundwater.

What if plastic dumped into mantle of earth?​

Answer»

2 reasons:    There are just not many areas in the world with active volcanoes, or as you put it, “molten lava pit”. Developing the technology and infrastructure to do so for the tiny number of countries that can do it just doesn't make sense.    It is far more complicated than you think to build an entire infrastructure around a region that is, by DEFINITION, likely to fall apart at any moment. The lava could flow out, rendering the transport chain useless. Or the entire ground around it could collapse from the shifting liquid underneath, burying all infrastructure.    OK I lied. There is a 3rd reason. The vast majority of our (non recyclable) waste is combustible. Throwing it into a lava pit wouldn't bury it, but rather combust it into a whole mixture of noxious gas that harms people and the environment. If you're going to combust it ANYWAY, there are existing infrastructure AVAILABLE to handle waste: waste incinerators. These systems:        Can be built anywhere as it does not depend on specific geography.        Is a long lasting investment that can be built to last long enough to recover cost. Also, it is proven commercial technology that requires no new R&D.        Already captures the waste gas and breaks it down into harmless (less the greenhouse effect) products that can, for the most part, be safely released into the atmosphere.648 views · View 6 UpvotersRelated QuestionsMore Answers Below    Why don’t we start dumping waste into active volcanoes instead of a landfill?    Can spent plutonium be put back into the EARTH, via an active volcano, to melt it again and join the potassium and iron ferrite core of this p...    Why don't we launch trash into space?    Why can't toxic and/or nuclear waste be disposed of in volcanoes?    Why can't we get rid of our trash by tossing it into a volcano?RYAN CarlyleRyan Carlyle, BSChE, Subsea Hydraulics EngineerAnswered Sep 6, 2013 · Author has 1.5k answers and 13.6m answer views    There are cheaper ways to incinerate trash. Most garbage is paper and plastic, which would simply combust immediately. Then it forms air pollution.    Molten rock is much denser than 99% of what we throw away. So any trash that survived the heat (or just slag/ash from burned trash) would float on the surface of whatever lava pool we were attempting to use for disposal.Explanation:

Kunal took few iron turnings and mixed them well with Sulphur powder. He could separate the iron turnings with the help of a magnet. He heated the mixture for some time and tried to separate the iron turnings with the magnet but he could not. Why? a. On heating, a chemical change takes place and a new compound is formed. b. On heating, iron becomes non-magnetic hence, it is not attracted by magnet. c. On heating, a physical change takes place hence iron and Sulphur get mixed up. d. On heating, iron evaporates and only Sulphur is left behind.

Answer»

re of iron and sulfur would be a heterogeneous mixture. Iron is a metal and sulfur is a powder. When sulphur and iron filings are mixed and heated they form Fes (ferrous sulphide). The FeS is in black colour.The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat) PAGE 2 Maine Geological SURVEY | 2 One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million atoms of sulfur) react with heat to make one MOLECULE of iron sulfide (or a million MOLECULES of iron sulfide).i HOPE that my answer helps
