FAQ

My school project is to invent something that has NEVER been inventedI actually had a legitimate idea but I have this feeling it has already been takenIf it has been invented, what are some simple school-project style inventions I could make?

The density of aluminum is 2.70 g/cm3A square piece is 21.89cm and weighs 2.514 gThe answer should be in millimetersI got 1.9 x10^-2 and im wrong, but I dont know whyI keep getting the same answerPlease helpThanks
What ammo are you shooting? If it's low grade stuff, I would think that is your problemIve put about 600 through my Glock with 0 problems.
Plz help me with these following questions as well.I've been trying to get the right answers for so long but i can't find it.but I do have the answers of the questions.what i need is the steps.2.What is the mass of 2.3 moles of aluminium oxide?3.What is the molar mass of tetrachloromethane, CCl4?4.How many moles of aluminium ions are present in 17.12g of aluminium sulphate?5.What is the formula mass of iron(II)Sulphate-7-water, FeSO4 7H20?I really need help in these questions.Thx
The formula Al2O3 means that 1 mole of Al2O3 has 2 moles of Al ions and 3 moles of O ionsSo, any sample of Al2O3 will always have a 2 to 3 ratio of Al and OIn your 0.4 mol of Al2O3, there are 0.8 mol of Al ions and 0.12 mole of O ions since 0.8 to 0.12 is a 2 to 3 ratio 2.3 mol times 101.961 g/mol 234.5103 g rounded off to two sig figs, the answer is 230 g one C + 4 Cl 12 + (4) (35.5) 154 g/mol Using better numbers gives 153.823 g/mol Al2(SO4)3 convert 17.12 g to moles by dividing by the molar mass of Al2(SO4)3 multiply moles by 2 Get a periodic table to look up atomic weights FeSO4 7H20 one Fe one S four O 7 H2O (H2O 18.015, after awhile one gets that value memorized) Add them upThe dot between the FeSO4 and the 7H2O is not a multiplication dot.
What is the best way to cut a 100% perfectly straight line on a 10 inch long paper without messing it up?
We used a rotary-style paper cutter when I was a photographer in the NavyIt was much better than a chopper-styleNice, clean, straight cuts Without running out to buy extra equipment tho' I would have to say yardstick/razor knife/prayer is your best optionRemember to pray because the knife is very sharp and will likely cut into the straight edge, even one made of aluminum (I've done it), leaving you with a less than perfect cut and a damaged rulerPlus, there's the possible slip/jerk/bump/shift factor unless you clamp the stick downI think if you NEED the cut to be 100% perfectly straight, look into a rotary paper cutter.
A well Isolated container contains a mixture of 15 grams ice and 350 grams of water at a temperature of 0 C A 300 gram piece of aluminum is heated to a temperature of 140 C and is then submerged in the water-ice mixtureNo heat enters or leaves the container from the environmentthe specific heat of water is 4180 J/kg Cit takes 3.33x10^5 Joules of heat to melt one kilogram of iceThe specific heat of Aluminum is 900 J/kg C.awhat will be the final temperature of the solution? bActually, although heat may not go into the air, it will go into the containerIf the container is a 600 gram glass cup ( specific heat of glass is 664 J/kg C), the final temperature of the water-aluminum mixture will be lower than what you found in (a)What will be the final temperature?

Hypotheticaly if you were walking in the forest and happened across and red mushroom with white spots and you ate itWhat would your wonderland be? I mean like could it be like alice in wonderland or would it be effected by modern society? Have a happy trip!
Brown the pork chops first on both sides in a skillet on top of the stove, Then layer them in a baking dish and cover it with foilThey're really good if you put sliced potatoes in the dish first, and add a can of Cream of Chicken soup-and put the chops on top of the potatoes before you cover the dish with foilBake them at 400F for about 40-45 minutes, or until they reach the desired tenderness you likeThe potatoes will be tender and creamy and the chops will absorb the flavoring from the soup and practically fall off the boneThis is a delicious supper dishYou don't have to put potatoes in with them, but it's really goodIf you just want the pork chops by themselves, put them in the baking dish after browning with just a little bit of water-only about 1/4 cup-cover with the foil and bake.
I wish to rivet sheets of Tin over the windows in my old Leyland bus.will this cause any ill effect/harm? Thanks
There are several issues hereOne is that both aluminum and galvanized steel (which is what I think you mean by 'tin sheets') will corrodeAluminum corrosion is usually not a problem because it is self-limiting (the corrosion seals the surface of the aluminum and prevents further corrosion), but corrosion of galvanized steel is not and can eventually cause the sheets to completed disappearFortunately, this usually takes some timeYou didn't say how long you are expecting these 'patches' to lastThe other issue is galvanic corrosion at the point where the aluminum and galvanized steel come togetherAny time dissimilar metals are joined, there is a migration of electrons from one metal to the other that can cause corrosion of the jointI would not expect this to be any more severe than the corrosion that will take place where the bare steel is exposed (the rivet holes)Bottom line - I think there will be corrosion, but that the most likely effect is that the galvanized steel patches are more likely to suffer from destructive corrosion than the aluminum skin of the vehicle.
