I believe it would be either the Density or the composition of its matter
W₁=0.15 (15%)
p₁=1.0582 g/ml=1058.2 g/L
v₁-?
w₂=0.35 (35%)
p₂=1.1482 g/ml=1148.2 g/L
v₂-?
w₃=0.19 (19%)
v₃=35L
v₁+v₂=v₃ (1)
w₁=m₁/v₁p₁ m₁=v₁p₁w₁
w₂=m₂/v₂p₂ m₂=v₂p₂w₂
w₃=(v₁p₁w₁+v₂p₂w₂)/(v₁p₁+v₂p₂)
v₁p₁(w₃-w₁)=v₂p₂(w₂-w₃)
v₁/v₂=p₂(w₂-w₃)/[p₁(w₃-w₁)] (2)
We solve the equations (1) and (2).
v₁+v₂=35
v₁/v₂=1148.2*0.16/[1058.2*0.04]=4.34
v₁=28.446 L
v₂=6.554 L
Carbon, oxygen, & hydrogen may all be elements found in ethanol, but when separated, they have completely different chemical compounds. They are pure elements where as ethanol is a mixture.
The electronic configuration is for iron (Fe)
Answer:
a. True
Explanation:
Yes, the titration curve can determine or can reveal the pKa value of a weak acid.
Titration is a scientific method to estimate the dissolved substance concentration, known as the titrand, in a known volume when it reacts with another chemical substance of known volume as well as concentration. The other substance is known as Titrant.
When a weak acid like acetic acid is titrated to a very strong base such as NaOH, the titration curve is obtained and the pH value is noted. But the titration curve of any weak acid shows a characteristic shape. At the end of titration, the acetic acid will convert into acetate ions.
pKa is the negative logarithm of the Ka of the acid. pKa is the pH of the acid where the concentration of the weak acid as well as the conjugate base is in equimolar concentration.
