A single replacement reaction
<h3>Further explanation
</h3>
There are two types of chemical reactions that may occur.
namely single-replacement reactions and double-replacement reactions.
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Not all of these reactions can occur. We can use the activity series, which is a list of elements that can replace other elements below / to the right of them in a single replacement reaction.
This series is better known as the Volta series, where the metal element with a more negative electrode potential is on the left, while the element with a more positive electrode potential on the right.
The more left the position of a metal in the series, the more reactive metal (easy to release electrons, the stronger as the reduction agent)
The metal activity series is expressed in voltaic series
<em>Li-K-Ba-Ca-Na-Mg-Al-Mn- (H2O) -Zn-Cr-</em><em>Fe</em><em>-Cd-Co-Ni-Sn-Pb- (H) -</em><em>Cu</em><em>-Hg-Ag-Pt-Au </em>
Fe(more active element) takes the place of Cu(less reactive element) in the CuSO4 compound
1) temperature change
2)odor or smell change

Explanation:
Different butterfly species occupy slightly different niches, but most are forest- or field-dwelling, flying, nectar-feeding insects. ... During feeding, butterflies are often covered in pollen, making them effective agents of pollination for plants.
Answer:
NaCl will only conduct electricity in solutions
Explanation:
For electrical conduction, free mobile electrons as seen in most metals must be present or ions which are charged particles must be available for solutions and molten substances.
- Sodium chloride is an ionic compound without free mobile electrons or ions despite being ionic.
- It will maintain a subtle and unique charge stability when in solid form.
- In solid, the ions are not free to move and remain locked up in the solid mass.
- When introduced into a solution, the ions becomes free to move and this will aid electrical conduction.
