Answer:
Explanation:
In order to answer this question, we need to be familiar with the law of freezing point depression. The law generally states that mixing our solvent with some particular solute would decrease the freezing point of the solvent.
This may be expressed by the following relationship:
Here:
is the change in the freezing point of the solvent given its initial and final freezing point temperature values;
is the van 't Hoff factor (i = 1 for non-electrolyte solutes and i depends on the number of moles of ions released per mole of ionic salt);
is the freezing point depression constant for the solvent;
is molality of the solute, defined as a ratio between the moles of solute and the mass of solvent (in kilograms).
We're assuming that you meant 1.7-molal solution, then:
Given ethylene glycol, an organic non-electrolyte solute:
The freezing point depression constant:
Initial freezing point of pure water:
Rearrange the equation for the final freezing point and substitute the variables:
Answer:
the transition from water to steam is call evaporation.
Explanation:
water evaporates or vaporizes and turns into steam this typically happens when heat meets with the water. an example would be if you boil water steam will release from the pot, or when it rains, snows, etc (precipitation) the water evaporates and the ground dries.
According to the research, domain is the taxonomic classification level that is the largest or most broad.
<h3>What is domain?</h3>
It is the broadest taxonomic category in which known living things are classified.
In other words, it is the broadest category in which the different kingdoms of life can be organized, according to the classification models that are most widely accepted in the scientific community.
Therefore, we can conclude that according to the research, domain is the taxonomic classification level that is the largest or most broad.

Answer:
Primer postulado:
Así Bohr asumió que el átomo de hidrógeno puede existir solo en ciertos estados discretos, los cuales son denominados estados estacionarios del átomo. En el átomo no hay emisión de radiación electromagnética mientras el electrón no cambia de órbita.
