Let n ∈ Z^+ and denote by N^n =N×N×...×N (n times). Prove that N^n is countable for all n ∈Z+. Please answer questions in clear hand-writing and show me the full process, thank you (Sometimes I get the answer which was difficult to read).
Consider the possible structures of the N ion shown below + N=N=N-NEN 2 :N-NEN-NEN NEN-N-NEN N-N=N=N=N 5 NEN-N-N-N N=N-NEN-N: Based on formal charges, which structure ( #2 or #3) is the less likely arrangement of the electrons? Based on formal charges, which structure (#5 or #6 ) is a more likely arrangement of the electrons? What is the formal charge on the central nitrogen atom in structure 1? How many of the structures above represent likely arrangements for the electrons...
Given four chemical bonds N≡N N―N N=N N―C Determine if each of the statement is True or False. 1) The order of increasing bond energy is N―N < N=N < N≡N < N―C. 2) The N―C bond is shorter than the N―N bond because a C atom is smaller than an N atom. 3) The N≡N bond is stronger than the N=N bond because there are more bonding pairs of electrons. 4) There are two bonding pairs between the two...
