Problem 127d
One method to synthesize ionic solids is by the heating of two reactants at high temperatures. Consider the reaction of FeO with TiO2 to form FeTiO3. Determine the amount of each of the two reactants to prepare 2.500 g FeTiO3, assuming the reaction goes to completion. (d) Determine moles and mass (g) of FeO required.
- Look up the diameter of a silicon atom, in Å. The latest semiconductor chips have fabricated lines as small as 14 nm. How many silicon atoms does this correspond to?
