The residue left on evaporation will mostly be a mixture of three salts.The two definite ones are lead chloride and sodium nitrate formed by the double displacement between sodium chloride and lead nitrate.2NaCl (aq) + Pb(NO3)2 (aq) ——→ PbCl2 (s) + 2NaNO3 (aq)The third constituent will be either the unreacted NaCl or Pb(NO3)2 that is present in excess of the 2:1 molar ratio in which these two salts react as per the above equation.But if NaCl and Pb(NO3)2 are taken in the exact 2:1 molar ratio in the test tube with SUFFICIENT WATER, the contents on evaporation are expected to yield, at least theoretically, a solid mixture having only NaNO3 and PbCl2, in the 2:1 molar ratio. There should not be any unreacted NaCl or Pb(NO3)2 as a third constituent.

Michael FARADAY was born on 22 September 1791 in Newington Butts,which is now part of the London Borough of Southwark but was then a suburban part of Surrey. His family was not well off. His father, James, was a member of the Glassite sect of Christianity. James Faraday moved his wife and two children to London during the winter of 1790 from Outhgill in Westmorland, where he had been an apprentice to the village blacksmith.[10] Michael was born in the autumn of that year. The young Michael Faraday, who was the third of four children, having only the most basic school education, had to educate himself.

At the age of 14 he BECAME an apprentice to George Riebau, a local bookbinder and bookseller in Blandford STREET. During his seven-year apprenticeship Faraday read many books, including Isaac Watts's The Improvement of the Mind, and he enthusiastically implemented the principles and suggestions contained therein. He ALSO developed an interest in science, especially in electricity. Faraday was particularly inspired by the book Conversations on Chemistry by Jane Marcet.

Top 10 Benefits of Education

Poverty reduction :-

Many children living in EXTREME poverty do not have access to basic education, and lack of education is considered the root cause of poverty. For example, 171 million people could be lifted out of extreme poverty if all children left school with basic reading skills. That translates to a 12 percent drop in the world total. Additionally, learning improvements outlined by the Education Commission could help reduce absolute poverty by 30 percent.

Higher income :-

One of the benefits of education is the possibility of earning a higher income. An educated person has a better CHANCE of getting a higher paying job. For instance, earnings increase by approximately 10 percent with each additional year of schooling. Higher education allows people to specialize in certain fields, thereby opening numerous earning opportunities.

Promotes equality

Education is one of the greatest equalizers. In order to ensure that there are equal opportunities for everyone regardless of race, gender or social class, equal access to education is necessary. For instance, almost two-thirds of the world’s 775 million illiterate adults are women. This lack of education often deprives them of better job opportunities. In addition, access to education improves options for girls and women. In fact, a woman’s earnings can increase by 10-20 percent with each additional school year.

Health benefits :-

Children of educated mothers have a higher chance of living a healthier life. For example, they are more likely to be vaccinated and their growth is less likely to be stunted because of malnourishment. Children born to mothers with secondary or higher education are twice as likely to survive beyond age five compared to those whose mothers have no education.

Economic growth :-

Countries with high literacy rates have citizens with high PER capita income. In contrast, developing countries, where a large number of people live below the poverty line, usually have high illiteracy rates. For instance, in 2050, the GDP per capita in low-income countries will be almost 70 percent lower than it would be if all children were learning.

Discourages crime :-

Education shapes people’s sense of right and WRONG and it usually instills a sense of obligation to fulfill one’s duty to society. People living in poverty are among the most vulnerable. Hence, due to the lack of opportunities, they sometimes turn to illegal activities. Since education improves opportunities, it also helps people avoid these harmful activities.

Environmental benefits :-

Climate change and the resulting increased rate of natural disasters could cast as many as 122 million people into poverty by 2030. Green industries will rely on a highly skilled, educated workforce and education can make farmers more knowledgeable about sustainability in agriculture. Additionally, being ABLE to read and write enables a person to be more aware of environmental issues.

Reduces gender-based violence :-

In many areas, gender-based violence negatively affects girls’ right to education. Fear of physical violence deters many girls and women from going to school. However, education can also positively affect people’s mindset, thereby discouraging violence.

Reduces child marriage :-

Child marriage is a big concern in many developing nations. Education can reduce this dangerous practice, as each year of secondary education reduces the likelihood of marrying as a child by five percent. In fact, completion of secondary education is strongly correlated with girls delaying marriage.

Reduces maternal death rates :-

Education can improve maternal death rates. Maternal death rates would drop by two-thirds if all mothers received primary education. That would save 189,000 lives.
