i hope this is correct
Answer: I think the alcohol molecules slip between the water molecules and take up that space, so you have less that you started with.

Answer:
Explanation:
pH is derived from the concentration of hydronium ions in a solution. Hydrocyanic acid is HCN.
First, we shall figure out the moles of HCN:
If HCN was a strong acid:
HCN has a 1:1 ratio of H+ ions, the moles of H+ is also the same.
To find the molarity, we now divide by Liters. This gets us:
Finally, we plug it into the definition of pH:
![pH = -log[H^{+} ]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%20%5D)
However, since HCN is a weak acid, it only partially dissociates. The 
of HCN is 
.
![K_a = \frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=K_a%20%3D%20%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
We can use an ice table to determine that when x = H+,
![[H^+] = 8.83*10^{-6}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%20%3D%208.83%2A10%5E%7B-6%7D)
look at the atomic number using the periodic table. The Atomic number equals the amount of protons and the amount of protons equals the amount of electrons
The answer is: C. A failed constitutional amendment.
The Equal Rights Amendment (ERA) is a proposed amendment to the United States Constitution.
This amedment is designed to guarantee equal legal rights for all American citizens regardless of sex.
Hawaii was the first state to ratify ERA, followed by approximately 30 other states.
During the mid-1970s, a conservative women in opposition eroded support for the Equal Rights Amendment and amadment failed to achieve ratification.
