Butene is an alkene, which is a hydrocarbon that contains a double bond. At room temperature, butene occurs as a gas. So, when it reacts with oxygen gas, it will yield gaseous products, carbon dioxide and water vapor. The complete balance reaction is written below:
C₄H₈ (g) + 6 O₂ (g) → 4 CO₂ (g) + 4 H₂O (g)
Start by adding ten to 90 then subtract ING one
This is so frustrating I don’t even understand this

Explanation:
The solution before dilution and after dilution contains same number of moles, and water is added for dilution.
Option B
<h3><u>Explanation:</u></h3>
Suppose before dilution, the solution contains x moles of KCl in Y liter of water. Now as the concentration got halved, then the solution contains x moles of KCl in 2Y kiters of solution. So the number of moles of KCl in the solution remained constant.
Again, as the solution is diluted to half of the concentration, water must have been added with the solution to make it dilute.
