Answer:
Adakah benar anda tidak boleh mencuci rambut, minum air sejuk dan
makan ais krim atau bersukan semasa haid? Terangkan jawapan anda.
Tidak, ini tidak benar, melakukan semua ini baik-baik saja. Seperti, tidak ada yang dapat mempengaruhi kita, kerana tidak bersambung dengan sistem kita. Juga, mohon maaf jika bahasa itu salah kerana saya menggunakan terjemahan Google.
Semoga ini membantu :)
Answer:
When the batter hits the ball, there is a force applied, and energy is transferred. The ball will move in the direction the force is pushing it. If two objects collide, energy will be transferred between both, and there will be a change in motion.

Let the acid be HA.
The chemical formula for this acid will be the following:

The formula for the <span>acid dissociation constant will be the following:
</span>
![K_a= \dfrac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=K_a%3D%20%5Cdfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
<span>
We know [H+]=0.0001 (it's given).
However, we must find [A-] and [HA] in order to solve for the constant.
We find that [A-]=[H+] by using a electroneutrality equation.
Also, we can create a concentration equation to find [HA].
</span>
![0.5M=[A^-]+[HA]](https://tex.z-dn.net/?f=0.5M%3D%5BA%5E-%5D%2B%5BHA%5D)
![[HA]=0.5M-[A^-]](https://tex.z-dn.net/?f=%5BHA%5D%3D0.5M-%5BA%5E-%5D)
<span>
Now, we can find the acid dissociation constant.
</span>
![K_a= \dfrac{[H^+][A^-]}{0.5M-[A^-]}](https://tex.z-dn.net/?f=K_a%3D%20%5Cdfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B0.5M-%5BA%5E-%5D%7D)
