electron energy levels caused in hydrogen cause these lines in the spectrum to be produced in this way because the wavelengths that are released when the electron move back to the ground state is specific and it varies accordingly. 2. Into which energy level are electrons dropping into to make these visible lines? The electrons are dropping back to the ground state which is the bottom most energy level to makes these visible lines. 3. What happens when the electrons drop into the 1st energy level

Bryan ==D Why would anyone use solar energy as an alternative energy to solve the world’s pollution problem? As humans‚ everyday we burn many different types of fossil fuels to produce ourselves electricity and to power up our vehicles‚ and so we create a lot of pollution‚ making this our own fault. With our modern technology and the abundance of the sun’s energy‚ solar energy has the ability to provide the world with electricity and different types of fluid (“Solar Energy”). Solar energy is ?e energy

Observations should include details of colour changes‚ precipitates‚ and tests on gases evolved. Tests on KA1 Test (a) Add dilute hydrochloric acid to a small amount of solid KA1‚ then warm gently. (b) Dissolve solid KA1 in distilled water and filter. Use separate portions of the filtrate for the following tests. (i) Add aqueous sodium hydroxide‚ then in excess. (ii) Add aqueous ammonia‚ then in excess followed by aqueous ammonium chloride. (iii) Add aqueous iron (III) chloride‚ then warm. (iv) Add aqueous

Identification of Metallic Ions Pre Lab Questions: 4pts 1. What are the learning goals of this experiment? To perform and observe the flame tests of some alkali and alkaline earth metal ion 2. Define ground state and excited state of an atom. Ground state- normal configuration of the electrons about the atom or the ion of an element; stable particle electrons are at lowest possible energy level Excited state- when stable particles are heated to very high temperatures some of the electrons leave

other races. The question of why there is racism is often left out of many history texts‚ as they seem to focus on the different wars of our time instead. However‚ the question of why racism exists is a very important one‚ as racism has been causes of many of the problems throughout history and today‚ such as the Civil War or the War in Iraq. In Howard Zinn’s book: A People’s History of the United States: 1492-Present‚ he explores the different reasons of why racism exists and how it may be stopped

of the soul. The most confusing aspect of this was the beginning of his argument. Socrates bases his argument from his un-doubtful acceptance of the soul existing and being immortal; although he is known to use questions and dialogue to explain the abstract ideas‚ I believe assuming it exists when trying to prove it actual existence defeats the overall purpose of an argument. In other words‚ if one accepts this first premise beforehand‚ their arguments

Why we can’t face god? Why angels exist? The Creator Himself is so powerful and glorious that He cannot be approached in person by human beings. He alone "hath immortality‚ dwelling in the light which no man can approach unto: whom no man hath seen‚ nor can see (1 Timothy 6:16). Angels do not have man’s shortcomings ‚ and can therefore act for God and represent Him when communicating with men and women. They bridge the huge gap between the holiness and perfection of God in heaven and the shortcomings

(Friends). In light of this‚ one of the many energy resources that countries will use to keep up with these demands is nuclear energy. Nuclear energy is the use of uranium that has been turned into fuel and put through reactors to generate energy‚ and is used to generate a large portion of the energy used around the world. But‚ nuclear energy is not as good as it sounds‚ countries should stop using nuclear energy and start using renewable energy because nuclear energy costs billions of dollars every year

conditions‚ unfair wages‚ unreasonable hours‚ child labor‚ and a lack of benefits for workers. Why do Sweatshops exist? They are a product of the global economy and the so-called “free” trade. Companies increase profits by driving down costs any way possible‚ so they set up low-cost factories. To minimize costs‚ companies look for places with the lowest wages and human rights protections. Where do Sweatshops exist? Sweatshops can be found all over Central and South America‚ Asia‚ and certain regions of
