This problem is providing us with the mass of hydrochloric acid and the volume of solution and asks for the pH of the resulting solution, which turns out to be 1.477.
<h3>pH calculations</h3>
In chemistry, one can calculate the pH of a solution by firstly obtaining its molarity as the division of the moles of solute by the liters of solution, so in this case for HCl we have:
Next, due to the fact that hydrochloric acid is a strong acid, we realize its concentration is nearly the same to the released hydrogen ions to the solution upon ionization. Thereby, the resulting pH is:
Which conserves as much decimals as significant figures in the molarity.

Answer:
The answer to your question is: HCl = 58.44 g
Explanation:
To solve this problem, we must remember the law of conservation of mass that says that, matter cannot be created or destroyed, only changes its form.
That means that, the mass of the reactants must be equal to the mass of the products.
Process
Sodium (Na) + Chlorine (Cl) ⇒ Sodium chloride (HCl)
22.99 g 35.45 g x
22.99 + 35.45 = HCl
HCl = 58.44 g
Answer:
To find the noble gas notation, you first take the noble gas before the element you’re trying to find the notation for. In this case, the noble gas before Calcium is Argon. You put the symbol for Argon in square brackets, and then you write out the rest of the notation as you would normally.
This would look like [Ar]4s^2
The 4s^2 is because Calcium is the second element in the 4s columns (refer to the diagram)
Hope this helps :)
Answer:
V₂ = 1223.2 mL
Explanation:
Given data:
Pressure of gas = 820.4 mmHg
Initial volume of gas = 900.0 mL
Initial temperature = 25.0°C (25+273=298K)
Final temperature = 132.0°C (132.0 +273 = 405 K)
Final volume = ?
Solution:
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 900.0 mL × 405 K / 298 k
V₂ = 364500 mL.K / 298 K
V₂ = 1223.2 mL
Ok I know this did it last year let's see chemical because you can't fix it back to its normal self
