The given question is incomplete. The complete question is as follows.
A certain liquid has a normal boiling point of
and a boiling point elevation constant
. A solution is prepared by dissolving some sodium chloride (NaCl) in 6.50 g of X. This solution boils at
. Calculate the mass of NaCl that was dissolved. Round your answer to significant digits.
Explanation:
As per the colligative property, the elevation in boiling point will be as follows.
T = boiling point of the solution =
= boiling point of the pure solvent = 
= elevation of boiling constant = 
We will calculate the molality as follows.
molality = 
i = vant hoff's factor
As NaCl is soluble in water and dissociates into sodium and chlorine ions so i = 2.
Putting the given values into the above formula as follows.


m = 100 g
Therefore, we can conclude that 100 g of NaCl was dissolved.
Answer:
Very dense.
Explanation:
Conceptually, you are taking a large amount of atoms and putting them into a small container. This means the spaces between atoms has to be smaller and the substance is more dense. (see image)
Mathematically, the equation for density is mass divided by volume (
). If you divide a big number by a small number, you still have a pretty big number (ex 4/2=2 versus 6/1=6)
Answer: Hello brainly stundents, The answer for this question is A charged Atom is actually called an ion, this charge occurs due to the indifference of electrons that are found outside the main nucleus of the atom
Explanation:
The right answer is N2(g) + 3H2(g) => 2NH3(g).
Ammonia (NH3) is produced by the synthesis of nitrogen (N2) and hydrogen (H2):
N2 + 3 H2 → 2 NH3
During the first half of the 20th century, the NH3-green was produced without CO2 emission at
from hydroelectricity, water, and atmospheric air.
H2 came from the electrolysis of water, the N2 of atmospheric air.
