Answer:
4500 cent
Explanation:
From the question, we were told that
a fence 80 meters long requires 30 nails per meter.
1 metre fence = 30 nails
Then 80 meters long= ( 30 × 80)
= 2400 nails
Which means a fence 80 meters long will require 2400 nails in total.
We need to find the cost in dollars for the nails to build a fence 80 meters long.
We know that 40 nails per box will cost 75 cents per box.
(2400 nails/40 nail per box)= 60 box
Then 60 box will be needed to complete the fence.
the cost in dollars for the nails to build a fence 80 meters long= (60 box × 75 cent per box)=4500 cent

Explanation:
A dissociation reaction is defined as the reaction in which a compound beaks down into two or more different parts.
For example, molecular formula of water is
and when it dissociates then it given hydrogen ion and hydroxide ion.
Therefore, dissociation reaction for water is as follows.

Thus, we can conclude that out of the given options
is the correct equation for the dissociation of water.
