Answer:
6.97 atm was the equilibrium pressure of HBr .
Explanation:
The value of the equilibrium constant =

Initially:
0 0 7.10 atm
At equilibrium
x x (7.10-2x)
The expression of equilibrium constant can be written as:


Solving for x:
x = 0.065
Partial pressure of HBr at equilibrium :(7.10 - 2 × 0.065) atm = 6.97 atm
6.97 atm was the equilibrium pressure of HBr .
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.

D = m / V
1.025 = m / 100,000 mL
m = 1.025 x 100,000
m = 102,500 g
