Answer:
Some natural resources like sunlight and wind are found everywhere, but other natural resources are unevenly distributed. Resources like oil, coal, and natural gas are only found where conditions were favorable to grow and preserve large quantities of animal or plant matter.
Explanation:
The bond angle varies depending on the type of bond between carbon atoms. For a single bond, its type is the sp³ hybridization. For this type, the bond angle between the carbon atoms is 109.5°. For sp² hybridization (double bonds), the bond angle is 120°. For sp hybridization (triple bonds), the bond angle is 180°. Thus,
A. This is an alcohol which consists of single bonds. So, the angle is 109.5°.
B. The angle is 180° because of the triple bond.
C. H₂C=C=CH₂ consist of a double bond, so the angle is 120°
It's the D. Skin hope you understand
Answer:
Only the valence shell are shown in the Lewis electron dot structures because, the chemical reactivity of an atom of an element is determined by the valence electrons of the atom and not by all the electrons of the atom including the inner electrons.
Explanation:
Lewis electron dot structures are structures that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
In the Lewis symbol for an atom, the chemical symbol of the element is written, and the valence electrons of the atom are represented as dots surrounding it. Only the electrons in the valence shell are shown using the Lewis electron dot structures.
Lewis structures for molecules show each atom and its position in the structure of the molecule using its chemical symbol. Dots or lines are drawn between atoms to show the electrons that are involved in the chemical bonding between the atoms in the molecule. Valence electrons in each atom that are not involved in bonding known as lone pairs, are represented as pairs of dots, and are placed next to each atom bearing the electron.
Electrons that are not in the valence level are not shown in the Lewis electron dot structures . This is because, the chemical reactivity of an atom of an element is determined by the valence electrons of the atom and not all the electrons of the atom including the inner electrons.
