Answer:
Any binary molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.
Explanation:
Going down in a group increases the atomic radius and a greater atomic radius implyes greater ionic radius.
When ionization takes place in these compounds they yelds protons (hidrogen ion) and an lewis base (anion). The greater the ionic radius the greater its stability, thus the periodic tendency is increaing the acidity of binary hidrogen compounds when going down a group. On the other hand going up a group decreases acidity, so any molecular compound of hydrogen and a Group 6A element above Selenium will be less acidic, so water and dihydrogen sulfide are less acidic in aqueous solution than hydrogen selenide.
Answer:
The equilibrium concentration of HCl is 0.01707 M.
Explanation:
Equilibrium constant of the reaction =
Moles of ammonium chloride = 0.573 mol
Concentration of ammonium chloride =
Initial: 0.573 0 0
At eq'm: (0.573-x) x x
We are given:
Calculating for 'x'. we get:
The expression of for above reaction follows:
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.01707 M
The equilibrium concentration of HCl is 0.01707 M.
