Answer:
Calcite
Explanation:
When in contact with hydrochloric acid, calcite releases carbon dioxide gas.
Answer:
See explanation
Explanation:
The mechanism for the formation of bromohexane from hexene has been clearly shown in the image attached to this answer.
Hexene is attacked by HBr and a carbocation is first formed as shown. The carbocation is flat and planar. it can be attacked on either face by the bromide ion.
Attack on either faces yields a racemic mixture of the R and S enantiomer as shown in the image.
You can use the mechanism shown to fill in the structures.
As another example, consider the downward force<span> of gravity that the Earth exerts on </span>you<span> (also </span>called<span> weight). In turn, </span>you<span> exert an exactly equal upward </span>force<span> on the Earth. Together, those </span>two forces<span> form an action-reaction </span>force pair<span>.</span>
