Imagine that you have a 5.50 L gas tank and a 2.50 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
When you heat up popcorn, it loses water explosively and it pops. suppose a kernel of corn, weighing 0.125 grams weighs only 0.106 grams after popping.
For the reaction Cu(s) + 2 Fe3+(aq) Cu2+(aq) + 2 Fe2+(aq), the equilibrium constant is Kc = 3.7×10^14 at 25 oC. Suppose that excess Cu(s) is added to 1.0 L of 0.015 mol L^-1 Fe(NO3)3(aq), with no change in volume. What is the equilibrium concent..
