Explanation:
Nitrogen trichloride NCl3 contains one nitrogen and three chlorine atoms. Each chlorine atom has three lone pairs of electrons while nitrogen has one lone pair of electrons.
The molecule geometry of the molecule is trigonal pyramidal while it's electron domain geometry is tetrahedral. Nitrogen is the central atom and is found in sp3 hybridization.
There is no formal charge on the molecule.
I would say that the density increases because the distance between the molecules decreases, and therefore becomes smaller, and vice versa the density increases, and that is a physical change not a chemical change.
Explanation:
The given data is as follows.
= 4.60 L, = 365 mm Hg
= 2.60 L, = ?
= (20 + 273) K = 293 K, = (36 + 273) K = 309 K
Since, number of moles of gas are equal so, according to ideal gas equation:
=
=
= 681.03 mm Hg
Thus, we can conclude that new pressure is 681.03 mm Hg.
Covalent bonding occurs when electrons are shared between atoms. Double and triple covalent bonds occur when four or six electrons are shared between two atoms, and they are indicated in Lewis structures by drawing two or three lines connecting one atom to another.
Powder. It will dissolve faster and should provide rapid pain relief.
