Answer:
0.100 M AlCl₃
Explanation:
The variation of boiling point by the addition of a nonvolatile solute is called ebullioscopy, and the temperature variation is calculated by:
ΔT = W.i
Where W = nsolute/msolvent, and i is the Van't Hoff factor. Because all the substances have the same molarity, n is equal for all of them.
i = final particles/initial particles
C₆H₁₂O₆ don't dissociate, so final particles = initial particles => i = 1;
AlCl₃ dissociates at Al⁺³ and 3Cl⁻, so has 4 final particles and 1 initial particle, i = 4/1 = 4;
NaCl dissociates at Na⁺ and Cl⁻ so has 2 final particles and 1 initial particle, i = 2/1 = 2;
MgCl₂ dissociates at Mg⁺² and 2Cl⁻, so has 3 final particles and 1 initial particle, i = 3/1 = 3.
So, the solution with AlCl₃ will have the highest ΔT, and because of that the highest boiling point.
wave length is what he decreased
9L!!! You take the moles of N2 in the reaction and then divide by one mole of nitrogen. Then you multiply that by the number of hydrogen moles in the reaction which in this case is 3. This gives you an answer of 3. You then take the number of hydrogen moles and multiply it by the 3L giving you 9L of hydrogen.
The chemical name is ferric oxide or iron (III) oxide or hematite. We can found it naturaly as a magnetite, mineral.

Explanation:
It would make sense for the United States to use SI units in everyday life because most calculations they do, in daily activities such as business and science, affect people in other parts of the world. For example, a United States writer who writes about weight in pounds(lb) and ounce(oz) might not be easily understood by a reader in many other countries of the world. This is because the reader might not be able to convert the measurement using the standards of the SI units where weight is measured in kilograms(kg).
The international system of units is the upgraded system of measurement from the metric system and it is used by almost all the countries of the world except three countries of which the United States is included.
