whats everyones mathematics skills? And what areas of maths do you reckon have helped you the most?

Hey, can anyone help me understand finding an degrees of an angle in a triangle? and how to use it to find the other sides, etc. Does anyone know of anyways to learn trig easy? thanx

would aluminium foil work?? conc acid??

NC based powder????

I just got some aluminium powder Does anyone know much about it? We used it in science for a thermite reaction Can it be used as an oxidizing agent? Is their anyway of making it at home? Is it surposed to be highly reactive with water? What is the ratio of ferric oxide and aluminium powder in thermite reaction? Can Potassium permanganate be used instead of Potassium Nitrate as an oxidizing agent? Also i tried to make potassium nitrate with sodium nitrate and potassium chloride by using crystalization, it didnt work thanx IcE pHoEnIx

Thanx for the info. Ummm this may seem silly but how do i measure stoichometricaly?

hey i was wondering if you can create KNO3 with KCl and NaNO3. I was told you can. If so whats the technique? Thankyou Icey

Clones, are they the same as the original? Physically and medically? Yes but mentally they are different. They are like indentical twins, if you may. They share the same genetic code, but they do not share environmental or life effects or experiences, they will be different mentally. So in a way they are indeed different. Unless we can figure out some way of transfering memories, etc into the other persons mind, they will be different. Does anyone here agree with me on this one?

hey,im trying to make a inertia diagram, of to cars crashing and explaining loose objects. but i dont know what forces to include etc. plz help thankyou

can anyone explain the relationship between the position of the elements in the periodic table and: electrical conductivity ionisation energy atomic radius melting points boiling point combining power(valency) eletronegativity reactivity thanx so much

does anyone know where i can find infomation and diagrams on ionic compounds in terms of repeating three-dimensional lattices of ions? Can anyone identify which common elements exist as molecules or as covalent lattices? Describe the physical properties of conductivity used to classify compounds as ionic or covalent molecular or covalent network? thanx so much

can anyone describe the formation of covalent molecules in terms of sharing of electrons.

How would i get pure copper from those plumber pipes? What would the plumber pipe be made of? can i use something else instead of H2SO4 when making batteries for example HCl or vinegar? thanx

Hey, i have some strontium-sup and iodine-sup used for marine fish tanks. would i be able to crystalize them and get strontium and iodine. thanx if i can, how do i do it? thanx

Hey i was wondering if anyone knew these questions. 1) Analyse the potential danger of loose objects in a vehicle. include a discussion on inertia in this analysis. 2)Discuss the addition of crumple zones and air bags to cars with respect to the concepts of impulse and momentum. If anyone could give me the formulas used to work this out it would be great Thanks Ice_phoenix87

ummm it is for a science project. im going to cut pieces of apple and banana and observe what happens

what would the variables and controls in this experiment be? What makes apples and bananas go brown?

1.can anyone identify the difference between elements, compounds and mixtures in terms of particle theory. 2. describe the phyiscal properties used to classify compounds as ionic or covalent molecular or covalent network. 3. describe using diagrams ionic compounds in terms of repeating three-dimensional lattices of ions. 4. identify which elements exist as molecules or as covalent lattices thanks guys it will really help me. hopefully i am not asking to much

i filed some zinc then mixed it with sulfur powder and heated it. lol but nothing happening. hmmmm what did i do wrong. i probably sound like an idiot.

whats doping? and whats the thread for the zinc sulfide? sorry to be a bother

lol ok lets try it.

oh ok, how many volts are in this experiment? can i get electrocuted badly?

im making that zinc sulfide. so i need powdered zinc.

a what? i dont think i have one of them lol. what else can i use

whats a flat bed scanner? where would i get a the plasma condiut?
