The value of Kc for the thermal decomposition of H₂S is 2.2 x 10⁻⁴ at 1400 K:
2 H₂S(g) ↔ 2 H₂(g) + S₂(g)
initial 3.5 M 0 0
at equilibrium 3.5 M - 2x 2x x
Kc = [S₂][H₂]² / [H₂S]²
2.2 X 10⁻⁴ = x(2x)² / (3.5 - 2x)²
2.2 x 10⁻⁴ = 4 x³ / (3.5)² Assuming x <<<<< 3.5
x = 0.088
Thus [H₂S] = 3.324 M
1/16 ( ignore this the stupid website just makes us use 20 characters UGH! )
answer:
ionic bonds form between oppositely charged ions
explanation:
- an ionic bond is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
- ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal.
- a covalent bond involves a pair of electrons being shared between atoms.
C. magnetic forces act at a distance
Explanation:
Since he was able to drag the keys along the table by moving the magnet, it shows that magnetic forces acts a distance.
Magnetism is a property exhibited by a wide range of materials.
Around a bar magnet, there are field forces in which the forces of the magnets are felt.
- Magnetic forces are non- contact forces. They don't need to be together to exert their force.
- This is why magnetic forces act at a distance.
