Instead of common salt if one component in the given mixture is sulphur how would you carry out separation process then |
|
Answer» Answer: Camphor and ammonium chloride on HEATING directly CONVERT into vapour. This is called sublimation. In contrast to this, sand and COMMON salt do not sublime. So from a mixture, containing ammonium chloride (or camphor), common salt and sand, ammonium chloride (or camphor) can be easily separated by the process of sublimation. On heating ammonium chloride (or camphor) converts into vapour leaving behind the non-volatile components. On cooling the vapour of ammonium chloride (or camphor) changes into solid. Common salt is soluble in water but sand is not soluble in water. When a mixture of common salt and sand in water is passed through filter paper, sand particle remain on the filter paper but other components of mixture i.e., common salt and water pass through filter paper. From a solution of common salt in water, common salt can be OBTAINED by EVAPORATION. For separation of different components of a mixture of ammonium chloride (or camphor) common salt and sand, methods of sublimation, Alteration and evaporation are applied.

Disadvantage of science |
|
Answer» Answer: The disadvantages of science and technology are : 1. it can be easily HANDLED by irresponsible people. 2. We will be too dependent on that.

If on the one hand, science and technology have brought us a lot of wonders, on the other hand, there are also disadvantages of science and technology. First, he has INCREASED anxiety in our lives. Second, when technology falls into the wrong hands, it can have a negative impact on society, such as the rising rate of cyber criminality , hacking, theft of personal information and pornography websites. Third, technology has also increased alternatives and opportunities for terrorists. In addition, technology has removed our physical efforts and we are getting more luxurious and comfort living. Economies lagging behind in the INTEGRATION of new technologies are seen as poor economies and their progress in the world is hampered. Science has been responsible for pollution and given us the nuclear bomb that threatens our very existence. But in this also the fault lies not in science, but rather in the intention of man to abuse the discoveries of science. Science is not intrinsically good or bad. It is a way to acquire knowledge in a systematic way. The disadvantage of new mobile phones is too many can communicate with us all at the same time. He can create scams and spam in many ways. YOUNG people have also been very addicted to gadgets that they can SPEND too much time with him. A disadvantage of production is the energy it uses. It consumes a lot of energy to run the machines. And so, we need more fuel, and that will leave a lot of waste and pollution to our environment. This is the most destructive price for the technology of our time. We cannot avoid the inconveniences that come with the benefits of technology. |

What happens when medicines are missed? |
|
Answer» Answer: Tiruvalluvar’s couplets in the Tirukkural are highly aphoristic: “Adversity is nothing sinful, but / laziness is a DISGRACE”; “Wine cheers only when it is quaffed, but love / intoxicates at mere sight.” Despite Tiruvalluvar’s reasonable tone, many of his IDEAS were revolutionary. He dismissed the caste system: “One is not great because of one’s birth in a NOBLE family; one is not low because of one’s low birth.” The poet maintained that goodness is its own reward and should not be regarded as a mere means to a comfortable afterlife. Chennai bus drivers have adopted the poet as their patron saint; his likeness is found ATTACHED above the windshields in the vehicles of the city’s official Tiruvalluvar Bus COMPANY. |
