Using a sample of 21.004 grams of aqueous waste leaving a fertilizer manufacturer has NH3 (ammonia.) is diluted with H2O (water) of 76.730 grams. An aliquot of 14.045 grams of this solution is titrated with 0.1043 M hydrochloric acid (HCl.) and it required hydrochloric acid (HCl solution) of 29.18 mL to reach the methyl red endpoint. Compute the weight % Ammonia (NH3) in the aqueous waste.
Nickel oxide crystallizes in the NaCl type of cystal structure. The length of an edge of the unit cell of NiO is 4.18A. What is the NiO bond length?
what do the bond angles of water suggest about the hybridization state of the oxygen atom of water?
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment.
