4. Consider two solutions, one formed by adding 11.68 g of sodium chloride (NaCl) to 1000 mL of water (d = 1 g / mL) and another formed by adding 36.03 g of fructose (C6H12O6) to 1000 mL of water.
a) Will the vapor pressure on the two solutions be the same at 60 oC? Calculate the expected vapor pressure for
each of the solutions (considering as an ideal solution) and explain why the differences.
b) Calculate the expected boiling temperature for these two solutions. Explain the reason for the differences.
Note: The tabulated values ​​must be verified in the book, or in class. Do not forget that the concentration is
species in solution and there is a difference in the dissolution of ionic and non-ionic compounds.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

maybe the spark is gone, love is a weird emotion and there is a possibility he may have found somebody else.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
