An exothermic reaction is a chemical or physical reaction that releases heat. It gives net energy to its surroundings. That is, the energy needed to initiate the reaction is less than the energy that is subsequently released. When the medium in which the reaction is taking place gains heat, the reaction is exothermic.When using a calorimeter, the total amount of heat that flows into (or through) the calorimeter is the negative of the net change in energy of the system.n energy profile of an exothermic reaction. by definition the enthalpy change has a negative value: in an exothermic reaction, gives a negative value for Î´H, since a larger value (the energy released in the reaction) is subtracted from a smaller value (the energy used for the reaction).
CENSUS: Welfare Recipients Outnumber Full-Time Workers ... (CNSNews.com) - Americans who were recipients of means-tested government benefits in 2011 outnumbered year-round full-time workers, according to data released this month by the Census Bureau. They also out-numbered the total population of the Philippines. There were 108,592,000 people in the United States in the fourth quarter of 2011 who were recipients of one or more means-tested government benefit programs, the Census Bureau said in data released this week. Meanwhile, according to the Census Bureau, there were 101,716,000 people who worked full-time year round in 2011.
What is 'Welfare'. Welfare is a government program which provides financial aid to individuals or groups who cannot support themselves. Welfare programs are funded by taxpayers and allow people to cope with financial stress during rough periods of their lives. In most cases, people who use welfare will receive a biweekly or monthly payment.
