Answer:
strong attraction of solute particles to solvent particles
Explanation:
Solubility occurs when the solute-solvent attraction is more than the solute-solute and solvent-solvent interactions.
<u>A solute solubles in the solvent when the solute solute interactions and the solvent solvent interaction decreases and there is more strong interaction of the solute particles to the solvent particles. </u>
Answer:
0.52 g of KNO₃ are contained in 19.7 mL of diluted solution.
Explanation:
We can work on this problem in Molarity cause it is more easy.
Molarity (mol/L) → moles of solute in 1L of solution.
100 mL of solution = 0.1 L
We determine moles of solute: 44.7 g . 1mol /101.1 g = 0.442 mol of KNO₃
Our main solution is 0.442 mol /0.1L = 4.42 M
We dilute: 4.42 M . (11.9mL / 200mL) = 0.263 M
That's concentration for the diluted solution.
M can be also read as mmol/mmL, so let's find out the mmoles
0.263 M . 19.7mL = 5.18 mmol
We convert the mmol to mg → 5.18 mmol . 101.1 mg / mmol = 523.7 mg
Let's convert mg to g → 523.7 mg . 1 g / 1000 mg = 0.52 g
Answer:
when lithium forms an ion it donates 1 electron
which makes its electron configuration to become 2
Answer:
Low power
Explanation:
Low power would allow for the full image of the red blood cells and would appear as small circles.
