Answer:
<em>H.vap = 6.544 kJ/mol</em>
Explanation:
Clausius-Clapeyron Equation
<em>In P = H.vap / RT</em> where T = 20 + 273 = 293K
H.vap = In P (RT) = In 11 (8.314 x 293) = 6543.861 J/mol = 6.544 kJ/mol
You should first count all the valence electrons. Then draw the central atom and single bonds to the rest (then go from there)
According to Henry's law:
C = K P when,
C is the solubility of a gas at a constant temperature in a particular solvent.
K is the Henry law constant
p is the pressure of the gas
we have the pressure and the solubility so we will get the K at first:
by substitution:
0.153 = K * 0.37atm
K= 0.4
∴ C when P = 2.4 atm
∴ C = 0.37 * 2.4 atm = 0.888 = 88.8 g/100g H2O
Answer:
B. They bond identical atoms together
Explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
<em>(figure attached)</em>
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.
