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.
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.
- 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.
Answer:
Excess Reagent = oxygen
Explanation:
Limiting reagent: The substance that is totally consumed when the reaction is completed.
Excess reagent: The substance left after the limiting reagent is consumed completely
The balanced chemical equation for formation of water is as follow:
This means when 2 moles of hydrogen reacts with 1 mole of oxygen, 2 moles of water is produced.
Hence the ratio in which hydrogen and oxygen gas reacts is 2:1
Now if 2 mole hydrogen require 1 mole of oxygen ,then 4 mole hydrogen need 2 mole of oxygen.
or
Here 5 mole of oxygen is reacting but only 2 mole is required .
Oxygen is in excess.
