Answer:
109.5°, 120°, 109.5°
Explanation:
The bond angles that are marked as a, b and c in the given molecules is in the order of :
Angle a : 109.5°
Nitrogen is 
hybridized and the geometry is tetrahedral. So the bond angle is 109.5°
Angle b : 120°
Carbon is 
hybridized, so the shape is trigonal planer and the bond angle is 120°
Angle c : 109.5°
Carbon is hybridized and the geometry is tetrahedral. The bond angle is 109.5°
Hi
The nucleation reaction called : The physical reaction
I hope that's help !
Answer:
0.74°C
Explanation:
The freezing point depression is a colligative property that can be calculated using the following expression.
ΔTf = Kf . b
where,
ΔTf: depression in the melting point
Kf: freezing point depression constant
b: molality
The mass of the solvent (benzene) is:
The moles of solute (naphtalene) are:
The molality of naphtalene is:
ΔTf = Kf . b
ΔTf = (4.90°C/m) . 0.972m = 4.76°C
The melting point of the solution is:
5.50°C - 4.76°C = 0.74°C
All " transuranium elements " ( i.e. an atomic number greater than 92 ) are unstable. Elements in the same family have similar properties. Based on this logic, one would expect seaborgium ( Sg ) to have similar properties to tungsten ( W ), which is directly above it in the same family.Elements of atomic mass 92 and above being most unstable called the transuranium group of elements is found to have many common properties and becomes difficult to judge on the basis of properties. Atomic number is the number of protons in the nucleus of the atom and it describes the chemical property of the elements.
