Answer:
NaOH(s) --> Na+(aq) + OH–(aq)
Step-by-step explanation:
A basis of Arrhenius is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution.
So the answer is :
NaOH(s) --> Na+(aq) + OH–(aq)
The perimeter of the triangle will be 41ft
<h3>The perimeter of a triangle</h3>
The perimeter of a triangle is the sum of all the sides of the triangle
From the given triangle, we need to get the third sidee firse as shown:
h² = 12² + 12²
h² = 144 + 144
h² = 288
h = 17ft
Perimeter = 12 + 12 + 17
Perimeter = 41ft
Hence the perimeter of the triangle will be 41ft
