Answer:
K2SO4, NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20
Explanation:
Substances are soluble in water when they are ionic or polar covalent substances.
If we look at the substances listed, K2SO4 is ionic while NH3, HOCI, HCI, CH3NH2, SiCl4, CO2, CH20 all contain polar covalent bonds which accounts for their water solubility.
Hence ionic and polar covalent substances are soluble in a polar solvent such as water.
pKa= -log(ka)
= -log(2.3*10^-9)
= 8.64
Now pH can be calculated using equation:
pH=pka+log(BrO-)/(HBrO)
8.08 =8.64+log(BrO-)/(HBrO)
log(BrO-)/(HBrO)=8.08-8.64
= -0.56
(BrO-)/(HBrO)= 10^-0.56
=0.275
No idea.. I think if you take angle (<) MNL then divide those...
Non polar covalent bond. The Cl's electronegativity is the same since it's the same atom. Therefore, they will be nonpolar
