![]() ![]() Huge piece cracked off lid of IBM Thinkpad. Avoid a broken jack like the plague, unless you have the knowledge to fix it, or the price reflects the damage. Even for those systems that have a separate piece, the system will need to be completely disassembled, which is not for the faint of heart or a novice. ![]() For most laptops, the DC jack is an expensive repair because the jack is soldered to the motherboard. Ironically, physical damage to the plastics of the jack does not interfere nearly as much as internal damage. Sometimes you will be able to see the damage, but most likely you will not. The system should turn on with a battery, but by that point, yours will already be dead. After some time, the jack will break completely and the system won't turn on with the AC charger at all. The system ends up charging slowly or not at all and completely destroys the battery. You don't know how many times I've seen a person buy a system that looks great, but has a loose DC jack. Meet at a public place where you can plug the machine in. BIOS passwords on laptops are usually on a non-volatile chip (not affected by power loss). That trick works on desktops, and you will see a lot of people on forums suggesting it, but for most laptops, it does not work. Remember, on a majority of laptops, you can't remove the BIOS password by just removing the CMOS battery. Craigslist desktop computer software#There are BIOS cracking software from SOME systems, but it is not easy and on a slippery legal slope. In most states, you will be REQUIRED to return the stolen item if you are found to possess it, or worst, you will end up in jail. Lastly, if the seller has a system with a BIOS password, and doesn't know what it is, more likely than not, the item is stolen. A harddrive-based password will keep you from accessing the original hard drive, and in some special cases, from even putting in your own. There are sometimes ways around this, but they require time, effort, and a trained technician. However, if there is a BIOS password, you will not be able to change the order of the drives. ![]() For some reason, the customer may need to reinstall Windows (it happens to all of us) and needs to change the boot priority to CD-ROM first. Another issue usually arrives too late for the customer to contact the seller. You are stuck in a permanent loop because you can't access the BIOS, but you can't start Windows without the correct time. On older systems, when the CMOS battery (the battery that holds date/time and other settings) is dead, suddenly the system will ask you to enter the current date without letting you load into windows. ![]()

![]() ![]() When halogens dissolve in mineral oil, they appear colored! Meanwhile, the Since halogens are also non-polar, they will haveĪ high affinity for dissolving in the non-polar mineral oil. Mineral oil is composed of long, non-polar hydrocarbon Halogens dissolve in mineral oil much more easily than Therefore, we need toįind a way to differentiate the halogens in the reaction in order to determine Unfortunately, halogensĭissolved in water appear very similar in color. If no reaction has occurred, you will see theĬolor of halogen X 2 (reactant) in your test tube. Reaction has occurred, you will see the color of halogen Y 2 To a test tube, then observing the color.

Successful completion of the exercise, you will be able to arrange the three halogens Conversely, Y¯ is being oxidized it is called the reducingĪgent because it is causing X 2 to be reduced. This reaction, X 2 is being reduced it is called the oxidizingĪgent because it is taking electrons away from Y¯, causing Y¯ to be The oxidation half reaction of Y¯ would be: Viewed as a half reaction the reduction of Reactions are best understood when written in terms of two half reactions. Redox reactions are best understood when written in terms of two half reactions.Ī Redox Reaction can be divided into two half reactions: ![]() Reaction of halogen X 2with halide Y¯ would be as F, Cl, Br, or I) and 'Y¯' denotes a halide ion. Reactions involve the exchange of electrons. Will be exploring the reactivity of the Group 17 elements as a reducing agent the halogens Cl, Br, and I) in reduction - oxidation reactions (referred Relative reactivities of three of the Group 17 elements This experiment is designed to allow you to determine the These periodic properties often influence theĬhemical reactivities of an atom. Ionization energy, electronegativity, and electron affinity also vary in similar manners (see the sections in your textbook). The video below provides an overview of the halogens.Figure 1: Trends in bonding atomic radii for periods 1-5 Halogen – One of the 5 non-metals in group 7 of the periodic table.ĭisplacement reaction – A reaction in which a more reactive element takes the place of a less reactive element in a compound. Halogens become less reactive as you go down group 7 in the periodic table, because the outer electron shell gets further away from the attraction of the nucleus, and so an electron is gained less easily.Ī less reactive halogen will be displaced by a more reactive one from an aqueous solution of its metal halide.Ĭhlorine + potassium bromide → potassium chloride + bromine Iodine (State of matter at room temperature) Solid (Colour) Grey/ black They form hydrogen halides, which dissolve in water, forming acidic solutions.įluorine (State of matter at room temperature) Gas (Colour) YellowĬhlorine (State of matter at room temperature) Gas (Colour) Greenīromine (State of matter at room temperature) Liquid (Colour) Red/ orange They form molecular compounds with non-metals.
