What is the metal ion in a metal nitrate solution M(NO3)4 if 90.52 g of metal was recovered after 4.00 hours of electrolysis at a constant current of 22.8 A? Enter the chemical symbol of the element, with correct capitalization. [F = 96,500 C/mol e–]
determine the number of resonance structures for nitrate ion, NO3- and Sulfur trioxide molecule SO3-. please explain?
Are the O-N-O bond angles greater in the nitrite ion (NC2-) or the nitrate ion (NO3-)? Please select the answer that best explains your conclusion. Nitrite has the greater bond angle because a trigonal planar bond angle is greater than a tetrahedral bona angle. Nitrite has the greater bond angle because a linear bond angle is greater than a trigonal planar bond angle. Nitrate has the greater bond angle because nitrite's lone pairs take up more space than bonds. Nitrate has the greater bond...
