A mettallurgist decided to make a special alloy. He melted 30 grams of Au(Gold) with 30 grams of Pb. This melting process resulted to 42 grams of an Au-Pb alloy and some leftover Pb. This scientist wanted to make 420 grams of this alloy with no leftovers of any reactants. how ...

Chemistry
Why do beryllium and fluorine combine in a 1 : 2 Ratio? Be is in group 2 (or IIA). F is in group VIIA (or 17 depending upon what system you are using). Therefore, flourine needs one electron to fill its outside shell. Be has two in its outside shell to give. So Be gives an ...

Pre-Calculus
It is well known that superman can withstand as much as 3 grams of Green Kryptonite indefinitely. However, exposure to more than 3 grams for more than 13 hours is fatal. Assume that Kryptonite decays at an hourly rate of 5.35% If superman is trapped in a room with 6 grams of ...
