State the name of its structure geometry. How many outer atoms and lone pairs are present in a molecule with a see-saw shape? How many different groups (either atoms or non-bonding electron pairs) surround the central atom in NO2-, and what is...
The yield of AlN powders was as high as 80% when the reactor temperature was 1000 掳C and the mole ratio of NH3/AlCl3 was 8. Most of the HCl by-product was recovered as NH4Cl outside the reactor. Powder characteristics, such as shape, size distribution and crystallinity, were also ...
