Which results in bond angle of 1 0 4 0 degrees in H 2 O and 1 0 2 0 in N H 3 . Calculate the average N-H bond energy in NH3(g). N2(g) --> 2 N 472.7 3 H2(g) --> 6 H 3*216 According to V S E P R theory, H 2 O has 2 lone pairs of electrons whereas N H 3 has only one lone pair. Why is the H–N–H angle in NH4 + identical to the H–C–H bond angle in CH4? See Answer. for NH3(g) = -46.11 kJ/mol, for N(g) = 472.7... 1)Calculate the average N-H bond energy in NH3(g).

What name of bond formed between NH3 and metal ion in complax (cu(NH3)4)²+ check_circle Expert Answer. for NH3(g) = -46.11 kJ/mol, for N(g) = 472.7 kJ/mol, for H(g) = 218.0 kJ/mol, for N2(g) = 0 kJ/mol, for H2(g) = 0 kJ/mol. Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? Start Your Numerade Subscription for 50% Off!Join Today. [math]NH3[/math] has bond angle [math]107[/math] degree (less than tetrahedral angle owing to increased repulsion to bond pairs from presence of lone pair at nitrogen). Both are polar. Estimate the length of the As H bond in AsH 3, the gaseous compound that de-composes on a heated glass surface in Marsh's test for arsenic.Which of these four hydrides has the weakest X H bond? * See Answer *Response times vary by subject and question complexity. After reacting with [math]HCl, NH3[/math] forms [math]NH4Cl[/math]. Polar covalent bonds are a type of bond where electronegativity's are unequal between non-metals. Rate! NH3 has a covalent single bond among its nitrogen and hydrogen atoms. Hence, repulsive forces between lone pair and bond pair is more in H 2 O . The bond lengths of the X—H bond in NH 3, PH 3, and SbH 3 are 1.02, 1.42, and 1.71 respectively. Want to see this answer and more? Median response … You have to make difference between the N-H bond and the NH3 compound. You need to put energy in to break the molecules into atom and then allow the atoms to for the 6 N-H bonds formed in 2 moles of NH3 (hence 6x where x is the bond energy of the NH bond). Want to see the step-by-step answer? Yes, it is a polar covalent bond. N-H is a polar covalent bond. In the bond N-H; because of the difference in electronegativity between N- and H- atoms.
