Answer:
- <u><em>Option D. has a great [OH⁻]</em></u>
Explanation:
1) Both <em>acids</em> and <em>bases</em> ionize in aqueous solutions so they are able to <em>conduct electricity</em>.
The ions, being charged particles, when flow through the solution are charge carriers, then they conduct electricity.
So, the option A does not state a difference between a solution of a base and a solution of an acid.
2) Both acids and bases are able to cause an <em>indicator color change</em>.
The usufulness of the indicators is that they are able to change of color when the pH changes either from acid to basic or from basic to acid. There are different indicators because none is suitable for the whole range of pH, but the statement B is not how solutions of base and acids differ.
3) The model of Arrhenius for acids and bases states that an acid is a substance that ionizes in water releasing H⁺ ions (this is equivalent to H₃O⁺) and a base is a substance that releases OH⁻ ions in water. Then, acids have a greater concentration of H₃O⁺ (so option C is not true for a solution of a base) and bases have a greater concentraion of OH⁻, making the option D. true.
As I am reading the problem, I see they gave you two pressures, one volume and they are asking for another volume. this should give you a hint that you need to use the following formula.
P1V1= P2V2
P1= 1.00 atm
V1= 0.50 ft³
P2= 3.00 atm
V2= ?
Now we plug the values
(1.00 x 0.50)= (3.00 x V2)
V2= 0.17 ft³
Answer: AgCH
Explanation: I hope this helps
The amino acid and which atom which has most to do with myoglobin’s ability to bind o2 is <u>histidine</u> and <u>haemoglobin</u> respectively
<h3>What is amino acid?</h3>
Amino acids simply refers to those molecular substances which combine together to form proteins. However, they are the end products of protein digestion
So therefore, the amino acid and which atom which has most to do with myoglobin’s ability to bind o2 is histidine and haemoglobin respectively
