<u>Answer:</u> The volume of NaOH required is 402.9 mL
<u>Explanation:</u>
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of HCl solution = 0.315 M
Volume of solution = 503.4 mL = 0.5034 L (Conversion factor: 1 L = 1000 mL)
Putting values in equation 1, we get:
- <u>For sulfuric acid:</u>
Molarity of sulfuric acid solution = 0.125 M
Volume of solution = 503.4 mL = 0.5034 L
Putting values in equation 1, we get:
As, all of the acid is neutralized, so moles of NaOH = [0.1586 + 0.0630] moles = 0.2216 moles
Molarity of NaOH solution = 0.55 M
Moles of NaOH = 0.2216 moles
Putting values in equation 1, we get:
Hence, the volume of NaOH required is 402.9 mL
thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top
Temperature is a measure of the internal energy of molecules.
When the pot is on the burner, the lower part of the pot acquires energy from the flame, this energy increases the temperature of the metal that is in contact with the liquid from the bottom, by a process of thermal conduction, while the liquid in the top is kept at the same temperature.
As time progresses, the hotter lower liquid, for which it has a lower with the metal bottom heats up by conduction. density, conscientiously rise and a transfer of heat is created by convection, which raises the temperature of the hot liquid and makes the liquid fall that is colder from the upper part than at the coming into contact
This cycle is repeated heating all the liquid. But the liquid with the liquid in the lower part always at a higher temperature than the liquid in the upper part, the process stops when the liquid in the lower part reaches the boiling point, than the passage from liquid to gas, during which the temperature remains constant.
With the thermal conduction and convection processes we explain the temperature profile: warmer at the bottom and colder at the top.

Answer:
[C] = 0.4248M
Explanation:
A + B ⇄ 2C
C(i) 1.68M 1.68M 0.00
ΔC -x -x +2x
C(eq) 1.68-x 1.68-x 2x
Keq = [C]²/[A][B] = (2x)²/(1.68 - x)²= 8.98 x 10⁻²
Take SqrRt of both sides => √(2x)²/(1.68 - x)² = √8.98 x 10⁻²
=> 2x/1.68 - x = 0.2895
=> 2x = 0.2895(1.68 - x)
=> 2x = 0.4863 - 0.2895x
=> 2x + 0.2895x = 0.4863
=> 2.2895x = 0.4863
=> x = 0.4863/2.2895 = 0.2124
[C] = 2x = 2(0.2124)M = 0.4248M in 'C'
<h3>
Answer:</h3>
Sodium
<h3>
Explanation:</h3>
- To answer the question we need to know a few things.
What are cations?
- Cations are positively charged ions that are formed when an atom of an element loses an electron(s).
What elements form cations?
- Metallic elements form cations since they react by losing electrons thus forming ions with a positive charge.
- For example, alkali metals such as sodium form cations with a charge of +1.
- In this case, sodium will form a cation with a charge of + 1, Na⁺
What are negatively charged ions?
- Negatively charged ions are known as anions.
- They are formed by non-metallic elements such as sulfur, argon, silicon, etc.

What are the properties of Saturated solution ?</h3>
A saturated solution is one that contains all of the solute that can possibly dissolve in it. The most sodium chloride that may dissolve in 
of water at 
°C is 
. Past that point, adding more 
won't cause it to dissolve because the solution is already saturated.
The solution reaches a point when it is saturated. This indicates that if you add more of the substance, it will stop dissolving and instead stay solid. The amount depends on how the solvent and solute interact molecularly.
