Answer:
The pressure of the gas is kept constant. If the Kelvin temperature of the gas is doubled, the volume of the gas is. O 1.
Answer: Disaccharides
Explanation:
Disaccharides can be defined as the combination of two monosaccharides which combines together to form a disaccharides.
These are formed by the combination of sugars. The process is hydrolysis as it releases water after the reaction is complete.
Two monosachrrides are joined together by the glycosidic linkage. Some common examples are maltose, sucrose and lactose.
The solution for this problem is:
C6H5NH3Cl is a strong salt: C6H5NH3+ + Cl- C6H5NH3+ + H2O <-----> C6H5NH2 + H3O+
K = Kw/ Kb= 1.0 x 10^-14 / 3.8 x 10^-10= 2.6 x 10^-5
=2.6 x 10^-5 = x^2 / 0.240-x
x = [H3O+] = 0.00251 M
pH = 2.60 is the concentration

Answer:
Only BF₃ is non polar.
Explanation:
The non polar molecule is one which will have zero dipole moment.
This zero dipole moment is possble if
a) the bonds are non polar (completely) and there is no lone electrons
b) the bonds are polar but the overall dipole moment cancel each other due to planar geometry of molecule
i) BF₃ : This is trigonal planar molecule. The overall dipole moment is zero due to symmetric distribution of electrons and thus dipole cancel each other.
ii) NF₃ : there is lone pair of electron and the bonds are polar.
iii) PBr₃: Again presence of lone pair of electrons and thus ssymmetric distribution of electrons
iv) BrCl₃ : The bonds are polar and molecule is not planar.
v) IF₃ : bonds are polar.
