Answer:

Mass of Cl₂ =  17.25 g

Explanation:

Given data:

Moles of hydrochloric acid = 0.485 mol

Mass of chlorine gas = ?

Chemical equation:

4HCl +  O₂ → 2Cl₂  + 2H₂O

Now we will compare the moles of Cl₂ with HCl .

                  HCl           :               Cl₂

                    4             :               2

                 0.485        :              2/4× 0.485 = 0.243 mol

Oxygen is present in excess that's why mass of chlorine produce depend upon the available amount of HCl.

Mass of Cl₂ :

Mass of Cl₂ = moles × molar mass

Mass of Cl₂ =0.243 mol × 71 g/mol

Mass of Cl₂ =  17.25 g

Determine the ph of a 0.18 m h2co3 solution. carbonic acid is a diprotic acid whose ka1 = 4.3 × 10-7 and ka2 = 5.6 × 10-11. dete
oee [108]
Answer is: ph value is 3.56.
Chemical reaction 1: H₂CO₃(aq) ⇄ HCO₃⁻(aq) + H⁺(aq); Ka₁ = 4,3·10⁻⁷.
Chemical reaction 2: HCO₃⁻(aq) ⇄ CO₃²⁻(aq) + H⁺(aq); Ka₂ = 5,6·10⁻¹¹.
c(H₂CO₃) = 0,18 M.
[HCO₃⁻] = [H⁺<span>] = x.
</span>[H₂CO₃] = 0,18 M - x.
Ka₁ = [HCO₃⁻] · [H⁺] / [H₂CO₃].
4,3·10⁻⁷ = x² / (0,18 M -x).
Solve quadratic equation: x = [H⁺] =0,000293 M.
pH = -log[H⁺] = -log(0,000293 M).
pH = 3,56; second Ka do not contributes pH value a lot.

Why do you think the transition metals are 10 columns wide?
Tasya [4]
The transition metals are 10 columns wide because they can hold no more than 10 electrons. This is why their width correlates with the number of electrons that are included in these metals. Transition metals include most commonly used metals, such as iron, copper, silver, and gold.
