Such complexes are highly labile and subject to rapid ligand exchange due to the d 9 electronic configuration of copper(II). Attempted dehydration of any of the hydrated copper(II) nitrates by heating affords the oxides, not Cu(NO 3) 2. [6] At 80 °C the hydrates convert to "basic copper nitrate", Cu 2 (NO 3)(OH) 3, which converts to CuO at 180 ...
Molecular weight (M.W.) (for molecular compounds) and formula weight (F.W.) (for non-molecular compounds), are older terms for what is now more correctly called the relative molar mass (M r). [8] This is a dimensionless quantity (i.e., a pure number, without units) equal to the molar mass divided by the molar mass constant .

Mole ratio: Convert moles of Cu to moles of Ag produced; Mole to mass: Convert moles of Ag to grams of Ag produced; The complete balanced equation would be: Cu + 2 AgNO 3 → Cu(NO 3) 2 + 2 Ag. For the mass to mole step, the mass of copper (16.00 g) would be converted to moles of copper by dividing the mass of copper by its molar mass: 63.55 g/mol.
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4. It forms hydrates CuSO 4 · n H 2 O , where n can range from 1 to 7. The pentahydrate ( n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [ 10 ] while its anhydrous form is white. [ 11 ]

Try to reach and maintain a healthy weight. Avoid smoking. If you have high cholesterol and lifestyle tweaks don’t help, the AHA notes that some people need to take medicine to lower their levels.
