Iodine has an electronegativity of 2.5, and potassium has an electronegativity of 0.8, so the difference is:
2.5 - 0.8 = 1.7
Answer:
The answer is A: Quantities of thousands are more common than quantities of trillions.
Explanation:
It's just kind of process of elimination. None of the other answers make as much sense

Answer:
3.5 mol·L⁻¹
Explanation:
1. Set up an ICE table.
2. Solve for x
The equilibrium concentration of NO is 1.0 mol·L⁻¹, so
1.0 = 2.0 - 2x
2x + 1.0 = 2.0
2x = 1.0
x = 0.5
3. Calculate the equilibrium concentration of I₂
[I₂] = 4.0 - x = 4.0 - 0.5 = 3.5 mol·L⁻¹
True, Iron is not buoyant in water because it has a greater density than water.
The buoyancy of an object in water has a lot to do with its density. The buoyancy of an object in water is proportional the difference between the density of the object and the density of water.
If the object is denser than water, the object will sink and not be buoyant in water. If the object is less dense than water, the object will float and be buoyant in water.
