Explanation:
NaCl is a strong salt of strong base and strong acid whereas HCl is a strong acid.
In the solution both dissociates in the solution into their respective ions as shown below:
NaCl ⇒ Na⁺ + Cl⁻
HCl ⇒ H⁺ + Cl⁻
Hence, the ions Na⁺, Cl⁻ and H⁺ are formed and there is no scope of reaction between them for a gas to evolve. They remain in the hydrated state in water.
The difference between the calculated voltage (based on standard potentials) and the actual voltage required to cause electrolysis is called overvoltage.
<h3>Electrolysis </h3>
Electrolysis is the technique of causing a chemical change in a substance by passing an electric current through it. The substance either loses or gets an electron during the chemical transition (oxidation or reduction). The procedure is carried out in an electrolytic cell, a device made up of positive and negative electrodes that are kept apart and submerged in a solution with ions that are both positively and negatively charged. The chemical that needs to be converted might either be dissolved in the solution or could form the electrode. The negatively charged electrode (cathode) receives electrical current (i.e., electrons), which travels there and combines with the components of the solution to convert them (reduced).

Answer:
Explanation:
average speed=distance travelled/time taken
distance=speed*time
15*10=150 m
1200 m/min=20 m/s
0.17 minute=10.2 seconds
20*10.2=204 m
2500 cm/s=25 m/s
5000 milliseconds=5 seconds
25*5=125 m
125+150+204=479 m
10.2+5+10=25.2
479/25.2=<u>19.0 </u>
If the strong force didn't exist, there would be nothing but hydrogen and neutrons floating in space. ... When the protons and neutrons are apart there is no strong force but when they are together to resemble a nucleus, the strong force is in action.
Answer:
D. The data supported the hypothesis
Explanation:
The data shows that rats fed a normal diet with the addition of vitamins gained a higher average weight gain in the period of 3 months, compared to rats fed a normal diet. This supports the scientists' hypothesis of "Young rats that had vitamins added to their food would gain weight faster than young rats fed a normal diet."
