If 4.00 kg of FeO3 are avaiable to react, how many moles of Co are needed? How man moles of each product are formed?
1)Balance the reaction Fe2O3 + 3CO --- 2Fe + 3 CO2 2) Convert 4 kg into grams you get .004 grams Fe2O3 3)Divide by 159 g/mol (the Molecular weight of Iron(III) oxide) you will get a very small number 2.51 x 10^-5 mol 4) For every mole of Iron (III) oxide you need 3 moles of Carbon Monoxide so just multiply by 3 and you will get 7.5 x 10^-5 moles
you could do it cheap and easy your self. go to your hardware store and ask for 2 half inch shark bite fittings and a foot of half inch pipe. you will also need to get a small copper pipe cutter. you can get that there too. very easy to do. cut the section out thats leaking and the fitting fit on by pressure, on major work, just make sure you shut the main water off first.
The mini tubing cutters in all the previous answers are probably available in good hardware stores, however, they are always available in automotive stores. They were designed to cut brake and gas lines, which are always tight up against the frame of a vehicle. Plumbers discovered them and now they're made in bright colors as well as the standard grey or chrome. RIGID is about the best quality plumbing tools you can buy.
This question is worth everyone's attention
Any hacksaw blade will work. They also make tubing cutters for tight spaces, only requires about an inch clearance to turn it.
