What is the structure of the ammonia molecule? | Socratic
2017年10月25日 · The ammonia molecule consists of 3 hydrogen atoms that are covalently bound to one nitrogen atom..... And thus we get a NH_3 molecule..... However, because nitrogen is electronegative with respect to hydrogen, charge separation occurs to give the following polarity, as electronegative nitrogen polarizes electron density towards itself: H_2stackrel(""^(-)delta)N-stackrel(delta^+)H And in ...

Ammonia Formula: Properties, Uses and Examples - Toppr
Ammonia. Ammonia Formula- Ammonia, azane or nitrogen trihydride, is the simplest inorganic base that is also an important source of nitrogen for many applications. Structure and Formula of Ammonia. Its chemical formula is NH 3 and the molar mass is 17.03 g/mol. It is a compound of hydrogen and nitrogen.
What is the molar mass of ammonia, "NH"_3? | Socratic
2015年11月21日 · "17.03052 g/mol". To determine the molar mass of any compound, all you have to do is add up the molar masses of every atom that makes up the respective compound. In this case, you know that ammonia, "NH"_3, is composed of one nitrogen atom, "N" three hydrogen atoms, "H" This means that its molar mass will be the sum of the molar mass of one nitrogen atom and three times the molar mass of a ...
Why is ammonia #NH_3# pyramidal and not trigonal planar (flat)?
2016年11月17日 · It is trigonal pyramidal because of the lone pair of electrons associated with the central nitrogen atom.
Molecular Geometry - Chemistry - Socratic
Molecular geometry is the spatial arrangements of atoms that are bonded in a molecule. ... and ammonia, # ...
How many atoms are there in a single molecule of ammonia?
2016年9月7日 · There are four atoms in a molecule of ammonia. The molecular formula for ammonia is "NH"_3. In a molecular formula, the subscript for each element indicates the number of atoms of each element. When there is no subscript written, it is understood to be 1. In one molecule of "NH"_3, there is 1 atom of "N" and 3 atoms of "H", for a total of 4 atoms.
What the shape of an ammonia molecule? - Socratic
2016年9月25日 · The ammonia molecule is a trigonal pyramid to a first approx., with /_H-N-H bonds angles = 104-5^@. How did we predict this shape? We know the ammonia molecule has 8 electrons to distribute nitrogen: one pair of electrons comprise the nitrogen-centred lone pair, and the other 6 electrons constitute the 3xxN-H bonds. There are thus 4 electrons pair to distribute around nitrogen. And their ...
What intermolecular forces are present in NH_3? | Socratic
2018年3月25日 · Dispersion forces and hydrogen bonding.... And of course, the most significant intermolecular force is hydrogen bonding. The normal boiling point of ammonia is -33.3 ""^@C...this is extraordinarily elevated as compared with the boiling points of the other Group 15 hydrides...PH_3, -87.7 ""^@C, AsH_3, -62.5 ""^@C,...and this series is comparable with the hydrides of the Group 16 elements. For H ...
7.The Molecular mass of ammonia is 17.a) How much is the GMM …
We can use the following formula to find the number of moles (n) of ammonia molecules: ``` n = mass (m) / molar mass (M) ``` * n = number of moles (unknown) * m = mass of ammonia (170 g) * M = molar mass of ammonia (17 g/mol) Plugging in the values: ``` n = 170 g / 17 g/mol. n = 10 moles ``` Therefore, there are **10 moles** of ammonia ...
