Explanation:
An ionic bond occurs due to electrostatic attraction between a positively charged ion and a negatively charged ion.
A metal and a ligand are bound by a coordinate covalent bond or a dative bond. This bond occurs due to donation of electron pairs from ligands to available orbitals on metals.
The formation of coordinate bonds is evident when neutral molecules or negative ions with non bonding electrons donate same to empty metal orbitals. This is sometimes shown by an arrow pointing from the ligands to the metal center.
For instance; tetraammine copper II ion is formed when four ammonia molecules donate a lone pair each to available vacant orbitals of the copper metal center to form [Cu(NH3)4]^2+.
Sulfur has two filled energy levels and six electrons on the third energy level. The corresponding electron configuration is A.
B is incorrect because there are no p orbitals at the first energy level, ie, no 1p orbitals. C is incorrect because the 4s1 electron would spontaneously drop into the 3p orbitals. D is incorrect because the 3d electrons would spontaneously drop into the 3p orbitals.
Answer:
Gases are more compressible
Explanation:
The particles of gases have weak forces of attraction making them move in constant random motion making them easier to compress

Answer:
True
Explanation:
Fe³⁺ is an oxidizing agent with E° = +0.77V. Zn metal is a reducing agent with E° = -0.76V. This is a "downhill" reaction, where the oxidizing agent has a higher E° than the reducing agent. Therefore, the reaction is spontaneous.
