Therefore, there are 1.505 ×1024 nitrogen atoms in 2.50 moles of NO2. The five outer shell electrons screen the nuclear charge quite poorly, with the result that the effective nuclear charge felt at the covalent radius distance is relatively high. Furthermore, the high stability of the nitrogen molecule contributes significantly to the thermodynamic instability of many nitrogen compounds, in which the bonds, although reasonably strong, are far less so than those in molecular nitrogen. A molecule is where two or more atoms … The element exists as N2 molecules, represented as :N:::N:, for which the bond energy of 226 kilocalories per mole is exceeded only by that of carbon monoxide, 256 kilocalories per mole. An active form of nitrogen, presumably containing free nitrogen atoms, can be created by passage of nitrogen gas at low pressure through a high-tension electrical discharge. Then she had the right answer. : Mole concept The number of moles in a compound is calculated by dividing the mass by its molar mass. Answered by | 26th Feb, 2013, 01:34: PM Because of this high bond energy the activation energy for reaction of molecular nitrogen is usually very high, causing nitrogen to be relatively inert to most reagents under ordinary conditions. 0 0. 2. Nitrogen is released from organic compounds when they are burned over copper oxide, and the free nitrogen can be measured as a gas after other combustion products have been absorbed. Density is defined as the mass per unit volume. NH4NO3 can be simplified to N2H4O3. 3. How many atoms of nitrogen are there in 0.50 mol of (NH4)2CO3?
