Copper and nickel can be mixed to form a corrosion-resistant alloy. If a particular alloy is prepared by mixing 11.2 moles of copper with 1.5 moles of nickel, what is the mass percentage of nickel in the alloy?
Write the balanced equation for neutralization of sulfuric acid and sodium hydroxide. How many mL of a 0.2 M solution of sodium hydroxide would be required to neutralize
Calculate the percentage of chlorine in a sodium hypochlorite powder (disinfectant for pools) if 5.0 kg of powder gives off 2.3 kg of chlorine.
write a electrn configuration for an octahedral complex, write the electron configuration for [RhCl6]^-3 in terms of MO labels for ground electronic state.
An unknown organic compound is mixed with 0.5190 g of naphthalene crystals to give a mixture having a total mass of 0.5959 g. The mixture is heated until the naphthalene melts and the unknown substance dissolves.
The mass spectrum of an organic compound shows the relative abundances of M to be 67.98% and M 1 to be 15.44%. Assuming the peaks are caused by 12C and 13C isotopes, determine the number of carbon atoms in the compound.
If 60.0 g of H3PO4 is dissolved in enough water to form 175 mL of solution, what is the molarity (M) of the solution?
An element has three naturally occurring isotopes with the following masses and abundances (in parenthesis): 27.977 amu (0.9222); 28.974 amu (0.0469); 29.974 amu (0.0310). Calculate the atomic weight of the element.
