What is the equilibrium expression for the following reaction: SO₂ (g) + H₂O (l) ⇌ H₂SO₃ (aq)? A. [SO₂] / [H₂SO₃]
B. [H₂SO₃] / [SO₂][H₂O]
C. [H₂SO₃] / [SO₂]

The drawing represents the movement of particles in a substance. what changes of state can this substance undergo

Answer explain why it is not possible to deduce a complete order of reactivity.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
