Answer:
Concentration of solution B is
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution,
where and are initial and final concentration respectively. and are initial and final volume respectively.
Here = , = 1.00 mL, = 10.00 mL
So, =
So, concentration of solution A =
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, =
So, concentration of solution B =
Explanation:
Hope this helps:)
Answer:4 significant figures
Explanation:
Answer:
The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.

Hope that made sense!
Answer:
CaO < BaO < KCl <KI
Explanation:
Let us remember that the solubility of an ionic substance in water depends on the magnitude of the lattice energy and the hydration energy. If the hydration energy is equal to or is greater than the lattice energy, the substance dissolves in water.
However, the lattice energy depends on the size of the ions. The smaller the ions in the ionic compound, the higher the lattice energy and the lesser the solubility of the ionic compound.
KI has the least lattice energy and the highest solubility in water while CaO has the highest lattice energy and the least solubility in water.
