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
The answer is column>soda straw>stalactite
Answer:
The pressure of the gas will increase.
Explanation:
This concept of change in state properties of gas, when compressed in a moveable piston-cylinder assembly, can be explained by using Boyle's law
Boyle's law states that the pressure of a given mass of gas is inversely proportional to its volume given that temperature remains constant.
Following this law, when the gas in the container is compressed to a smaller volume, the pressure will go up.
This is also because the gas is not free to move about without frequent collisions with itself and the walls of the container, due to the resulting smaller space after compression. Therefore, the force it exerts on the walls of the container and the frequency of collision are more.
Hydrogen should be your final answer.
