Answer from: zfghiiooi5

Zero Lone Pairs

Explanation:

Hydrogen Sulfate is made from Sulfuric acid. It is an ion and contains a negative charge on one of its oxygen atoms. The central atom of this ion is sulfur atom.

The lewis structure of hydrogen sulfate is attached below. It can be seen from the structure that the sulfur is carrying no lone pair of electrons as that carried by oxygen atoms. The sulfur atom is making four single or multiple bonds with oxygen atoms. Also, the electron and molecular geometry around sulfur is Tetrahedral.

Answer from: Quest

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.

chemical decomposition is opposite of chemical synthesis.

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
