All of the provided salts will increase the boiling point of water due to Boiling point elevation is considered as one of the colligative properties that only affected by the number of particles present in solution regardless their nature.
All of the choices are considered as electrolytes (ionizes in water) so the one which gives higher number of ions will raise the boiling point the most so the correct answer is A) AlCl₃ due to it ionizes to give 4 ions one Al and 3 Cl while NaCl gives only 2 ions, CaCl₂ gives 3 ions and KBr gives 2 ions
So the correct answer is A) 2.0 M AlCl₃
Answer:
8 of the electrons will be valence electrons
Explanation:
B. a large continent from long ago that eventually broke up into the continents we have today
He should buy the sander in store, this way it will be available for when he needs it.
Answer:
A) The mass would be the same.
Explanation:
Since there is no loss of any particle to vapor during the phase change process from solid to liquid, the mass of the before and after the process will remain the same.
- In this way, the law of conservation of mass is obeyed.
- Mass is the amount of matter contained in a substance.
- Since there is no room for escape or matter loss, the mass will remain the same.
