Answer:
In-F bond has the largest dipole moment.
Explanation:
Given the electronegativities:
Ge= 2.01
O= 3.44
H= 2.20
P= 2.19
In= 1.78
F= 3.98
B= 2.04
N= 3.04
The bond between Ge and O has an electronegativity difference:
ED= 3.44 - 2.01= 1.43
The bond between H and P has an electronegativity difference:
ED= 2.20 - 2.19= 0.01
The bond between In and F has an electronegativity difference:
ED= 3.98 - 1.78= 2.20
The bond between B and N has an electronegativity difference:
ED= 3.04 - 2.04= 1.00
As In-F bond has the largest electronegativity difference, this is the covalent bond with the largest dipole moment.
Answer:
Explanation:
Each value on the scale represents 10 times the previous value.
Subtract 1 from 6, so 10 to the power of 5 is the difference.
Answer:
Genotypes: Hh, Hh, hh, and hh
Phenotypes: Short Hair, Short Hair, Long Hair, Long Hair
Have a nice day! ^-^
This uses the concept of freezing point depression. When faced with this issue, we use the following equation:
ΔT = i·Kf·m
which translates in english to:
Change in freezing point = vant hoff factor * molal freezing point depression constant * molality of solution
Because the freezing point depression is a colligative property, it does not depend on the identity of the molecules, just the number of them.
Now, we know that molality will be constant, and Kf will be constant, so our only unknown is "i", or the van't hoff factor.
The van't hoff factor is the number of atoms that dissociate from each individual molecule. The higher the van't hoff factor, the more depressed the freezing point will be.
NaCl will dissociate into Na+ and Cl-, so it has i = 2
CaCl2 will dissociate into Ca2+ and 2 Cl-, so it has i = 3
AlBr3 will dissociate into Al3+ and 3 Br-, so it has i = 4
Therefore, AlBr3 will lower the freezing point of water the most.
