Answer:
I think this Is the correct answer
Explanation:
nitrogen is an element of atomic number 7 and so has 5 electrons in its valence shells. it requires 3 more electrons to complete its octet.nitrogen shares an electron with 3 atoms of hydrogen each to achieve this. hydrogen being an element with atomic number 1 requires 1 more electron to reach the electronic configuration of its nearest noble gas, helium. so it shares an electron with nitrogen

Answer:
100.223°C is the boiling point of an aqueous solution.
Explanation:
Osmotic pressure of the solution = π = 10.50 atm
Temperature of the solution =T= 25 °C = 298 .15 K
Concentration of the solution = c
van'y Hoff factor = i = 1 (non electrolyte)
c = 0.429 mol/L = 0.429 mol/kg = m
(density of solution is the same as pure water)
m = molality of the solution
Elevation in boiling point =
T = Boiling point of the pure solvent
= boiling point of the solution
= Molal elevation constant
We have :
(given)
m = 0.429 mol/kg
T = 100° C (water)
100.223°C is the boiling point of an aqueous solution.
Given data:
Diameter of the gold wire (d) = 0.175 cm
Length of the gold wire (l) = 1.00 * cm
Volume of the given gold wire = volume occupied by a cylindrical object\
= π * *l
here r = radius of the cross section
where : r = d/2
Hence the volume V = π * *l
=
Density of gold = 19.3 g/cm3
Weight of the gold wire = Density * volume
= *
