I need this for an presentation i have to do in chemistryNote I'm not a teacher and I have like $20 budget.
You should try to eat alot of protienNot protien drinks or supplements but foods with high protien like steakYou should eat heathy first before you take supplement or it could do more harm than goodBeef is a great source of protien and so is nutsFish is also good to eatWhile apples and carrots have little protien they have other important stuffMilk is also a GREAT sourceHope this helps.
fruits have natural sugar and since your body cant tell the difference between natural and proccesed its pretty much the same so watch how much fruit you eat so when snacking eat maybe some baby carrots and drink 2 glasses and see if your still hungry for big meals i usualy eat 2 - 3 egg whites or boiled eggs and a fruit for breakfast lunch is salad and tuna and dinner chiken or fish maybe red meat once a week with a green vegetable and fruit
Try to make the rule that you will eat protein with every mealLean protein, like skinless chicken breast, is bestProtein is also in foods like nutsCarry around healthy snacks like raisins and almonds when you're on the go, instead of giving in to fatty fast foodAnd if you have to, get a saladMcDonalds and Wendy's have really good onesAlso try to increase your fruit and veggie intake by two servings a dayIf you're craving something sweet, split a dark chocolate bar (it has antioxidants) with your friend - but make it a reward for make other healthy choices! Good luck!
The most dramatic one is to show aluminium's reactivityNormally Al forms a thin coat of aluminium oxide which protects it from further oxidationBut what if this is removed and there is just finely divided Al? ExperimentTake a piece of aluminium foil [ say 4 x 1.5 inches] and put it on a heat proof mat for safetyNow take a small wad of cotton wool and, using tongs, dip it in a no more that 5mL of mercury(II) chloride solution [ mercuric chloride if you use old names] and rub on the foil for about 20 seconds, then leave and watchThe foil gets quite warm/ hot and begins to grow dramatic hairy growths ExplanationThe mercury forms an amalgam [alloy, like almalgams in old dentistry] and the aluminium dissolved is freed of its oxide coat and can spontaneously oxidise to the white/grey hairy oxide coat Its quick, its easy, cost is very small but you should dispose of the remains in toxic waste and, like any chemistry, wash your hands afterwardsOther possibilities: a] Thermit reactionCheap and dramatic, but doesn't always work in inexperienced hands b] Anodising kitDem of how the Al surface film can be artifically colouredEasyc] Aluminium and iodineMix abot a teaspoon of aluminium powder and powdered iodinePut on a tin lid in a heapmake slight depression like volcanoNow prepare some water with a little washing up liquid in itUsing a dropper add two or three drop at the top of the volcano then waitAfter a short time it gets hot and gives off bright mauve iodine gas, then catches fire and form aluminium iodideNotedo in a fume cupboard or outdoorsSafe, but you migh have trouble getting solid iodineIt isn't cheap but you only need a few gramsSuggest you Google search a] or b] further if interestedAl + hydrochloric acid can be very slow in generating hydrogenIf you want to try this you'd get a better reaction with Al foil and sodium hydroxide solution [caustic soda] which reacts much better on gentle warming Should be something here good luck!
