NH3's shape is trigonal pyramidal, which has 1 e lone pairs and 3 bonding pairs, while BH3's shpe is trigonal planar, with 0 e lone pair and 3 bonding pairs. It's the force that electron lone pairs exert that pushes the molecules further and the repulsion force of lone pairs that aided in changing the shape of the molecules.
Hence, the shape are different ...
There are 15 moles of ammonia sulfate in the reaction of 30.0 mol of NH3. This goes from the formula 2 NH3 H2so take away (NH4)2So4.
12.01 g NH3 = 0.667 mol NH3 = 1 mol H2 = 2.0 g H2
Ammonia's chemical name is NH3, so the eleents found in it are 1 atom of Nitrogen & 3 atoms of Hydrogen. Hope that hepls! :P And ammonia is used for cleaning...
No, it's not balanced because the number of hydrogens and nitrogens on the left is not equal to the number on the right. 3H2 + N2 --> 2NH3
NH3, or ammonia, has a molar mass of 17.031 g/mol. So .500 moles of the substance would equal 8.5155 grams.

BH3 is non polar.Inter moleculer forces are much weaker Wander Voals forces.NH3 have hydrogen bonds among molecules.They are very strong comparing to Vander Woals forces.So NH3 have high boiling point.
Boron is in group 13, nitrogen is in group 15. In NH3 ammonia, the nitrogen atom achieves an octet , its four electron pairs are approximately tetrahedral In the planar BH3 molecule there are only 6 electrons around the boron which is said to be electron deficient and the three covalent bonds are at 1200. BH3 dimerises to form B2H6 which has bridging H atoms between the Boron atoms. This inceases the electron density on the B atoms but the octet is not achieved.
A trigonal planar molecule such as sulfur trioxide (SO3) or boron trihydride (BH3) has a trigonal planar shape. Trigonal pyramidal molecules such as ammonia (NH3) have bond angle closer to 107 degrees.
Ammonia (NH3) is an example.
pyramidal
Trigonal pyramidal (like NH3)
It has a lone pair.So pyramidal in shape.
Since NH3 has an free electron pair, it would be considered polar.
Ammonia has a lone pair.Its shape is trigonal pyramidal.
pyramidal
It has a lone pair.So it is trigonal pyramidal
