Answer:</h2>
- Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas.
example: Acetic acid
- Bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery;
example: sodium bicarbonate

Hey there!:
That depends on the pH of the water layer. If the water layer is basic or rather just not acidic, it will be in the water layer. If the water layer is acidic, pH 4 or less, it will be in the ether layer. On the question of upper and lower, either has a density of less than one so it will be the upper layer.
Answer:
1, 3, and 4
Explanation:
I'm guessing, but those make the most sense
<span>Answer:
CuX = Cu2+ + X2-
Ksp = [Cu2+] * [X2-]
for each mole of CuX that dissolves we get x mol of each of the anions and cations
Ksp = x^2 = 1.27 x 10 ^-36
x= 1.13 x 10 ^-18 moles of CuX per liter of pure water
if the solution has [Cu2+]= 0.27 M
Ksp becomes x ( x + 0.27)
as we can see above x is extremely small so can be ignored inside the brackets
0.27 x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.27 = 4.70 x 10 ^-36 moles per liter
In 0.19M X2- we have
Ksp = 0.19x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.19 = 6.68 x 10 ^-36 moles per liter</span>
We apply the ideal gas equation:
PV = nRT
V = 5 x 3.79/1000 m³
= 0.01895
T = 20 + 273 = 293 K
n = 15
R = 8.314
P = nRT/V
= (15 x 8.314 x 293)/(0.01895)
= 1,928,234 Pa ≈ 1.93 MPa
