Explanation:
<h2><u>Displacement reaction:</u></h2>
- A reaction in which an element displaces or replaces another element of a compound is called a displacement reaction.
<h3><u>Types:</u></h3>
There are 2 types:
<h3><u>1. Single displacement reaction:</u></h3>
- If one element displaces 1 other element of a compound, it is called single displacement reaction.
- <u>Example</u>:
- Here, 1 element (Fe) displaces 1 other element (Cu) of a compound.
<h3><u>2. Double displacement reaction:</u></h3>
- If two elements in two compounds displace one another, it is called double displacement reaction.
- <u>Example:</u>
- Here, Copper and sodium both displace each other.
The first one is right and so is eight you have to add them together to see if they go together if they dont add what is missing
Answer:
An object has potential energy (stored energy) when it is not in motion. Once a force has been applied or it begins to move the potential energy changes to kinetic energy (energy of motion).
Therefore, true. (Also would u mind giving brainliest, you don't have to hehe)
