Answer:
strength = 10⁻²/10⁻³ = 10 times more acidic
Explanation:
1. A solution with a pH of 9 has a pOH of
pH + pOH = 14 => pOH = 14 - pH = 14 - 9 = 5
2. Which is more acidic, a solution with a pH of 6 or a pH of 4?
pH of 4 => Higher [H⁺] = 10⁻⁴M vs pH of 6 => [H⁺] = 10⁻⁶M
3. How many times more acidic is a solution with a pH of 2 than a solution with a pH of 3?
soln with pH = 2 => [H⁺] = 10⁻²M
soln with pH = 3 => [H⁺] = 10⁻³M
strength = 10⁻²/10⁻³ = 10 times more acidic
4. What is the hydrogen ion concentration [H + ] in a solution that has a pH of 8?
[H⁺] = 10^-pH = 10⁻⁸M
5. A solution has a pOH of 9.6. What is the pH? (Use the formula.)
pH + pOH = 14 => pH = 14 - 9.6 = 4.4
Answer:
9.90

99 140-10-3.
99 140-10-3 is the compound number for trans-cinnamic acid.
<h3>What do you mean by compound numbers?</h3>
- A subscript is the little number that appears to the right of an element's symbol.
- That figure represents how many atoms of that element are contained in the complex.
<h3>What is the purpose of trans-Cinnamic acid?</h3>
- The creation of trans-cinnamic acid's methyl, ethyl, and benzyl esters is its primary usage, while it is also used to make flavors, colors, and medications.
- These esters play a significant role in perfume composition.
- The sweetener aspartame is a precursor of the acid.
<h3>What other name would you give trans-Cinnamic acid?</h3>
Phenolacrylic acid
- The class of chemical compounds known as cinnamic acids includes trans-cinnamic acid, often referred to as (e)-cinnamic acid or phenylacrylic acid.
- These are organic aromatic compounds that generate 3-phenylprop-2-enoic acid from benzene and a carboxylic acid group.

Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Electrochemical cell -
Device used for the conversion of chemical energy to electrical energy is called electrochemical cell.
it is based on oxidation reduction reaction.
Electrolyte is a solvent in which ions are dissolved and two electrodes are dipped in it.
Anode electrode is responsible for oxidation, and the cathode electrode is responsible for reduction.
The electrochemical cell is composed of two electrodes dipped in an electrolyte , and which are further connect by salt bridge .
Salt bridge firstly connects the circuit and allows the movement of ions and , resists any mixing of the solution , and helps to maintain the electrical neutrality condition .
Hence , from the question , the correct option about salt bridge is the first option .
Helium. If you're talking about waves in the air.
