ZnSO</span>₃ is zinc(II) sulphite. Zinc sulphite is salt.<span>
SO</span>₂ is sulfur(IV) oxide. Sulpfur oxide is oxide. Oxidation number of sulfur is +4 and oxygen has oxidation number -2.
Answer:
The genetic element is the insulator.
Explanation:
The insulator is a basic component of the eukaryotic genomes. In recent studies, insulators have been found in many eukaryotic cells ranging from yeast to human. These genetic elements can clog the enhancer–promoter communication and can also prevent the movement of repressive chromatin. They also can be used to restrict the actions of silencers and enhancers in the system. Insulators can also efficiently protect the gene expression from the negative and positive chromatin effects. Another important function of the insulator is to serve as a regulatory element and prevent genes from unnecessary regulatory interactions.
Answer:
Electron pair geometry - tetrahedral
molecular geometry- trigonal pyramidal
Explanation:
According to Valence Shell Electron Pair Repulsion Theory, the shape of a molecule is determined by the number of electron pairs around the central atom in the molecule. Lone pairs distort a molecule away from its expected geometry based on VSEPR. This is why the electron pair geometry differs from the actual molecular geometry.
PCl3 has four regions of electron density, three substituents and one lone pair hence its electron pair geometry is tetrahedral. However, the three substituents are arranged in a trigonal pyramidal geometry(its molecular geometry).
