Answer: heck the chemistry app itll help you i dont know this answer but the app will tell u!
Answer:
A double bond between carbon atoms
Explanation:
The suffix -ene is used for alkenes, which tells you that the molecule has a carbon-carbon double bond.
A chemical reaction is marked by new substance formation. The energy changes in chemical reactions occur when atoms <u>rearrange</u> to form new substances.
<h3>What is a chemical reaction?</h3>
A chemical reaction is said to be the process that is characterized by the formation of new substances by the alteration of the chemical composition and the properties of the compound or the molecule.
The reaction results in a new product by the rearrangement of the atoms of the reactant molecule by breaking and creating chemical bonds. The bonds are altered by the change in energy.
Therefore, <u>rearrangement </u>is the correct blank.

C. A solution is any two liquids mixed.<span />
The reaction is a displacement reaction. Iron is more reactive than copper. Hence, it displaces copper,forming iron II sulfate and copper metal.
This reaction is an exothermic reaction, hence it releases energy. The colour change indicates that iron has displaced copper.
