What is the Polarity of water?</h3>
Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.
Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.
Since water molecules are polar, they are more attracted to molecules that are also polar.
Thus, based on the observations from, the substance that water is more attracted to are polar substances.

Answer:
The death of Jesus was a unique, one of a kind, once for all death that ransomed mankind from sin and satisfied the righteousness of God and made it possible for man to once again have a personal relationship with God. The simple definition of death is separation.

Answer:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

Answer:
The concentration of hydronium ions is 0.0155 mol/L
Explanation:
The aqueous solution ionization reaction for nitric acid is as follows;
HNO₃ + H₂O → NO₃⁻ + H₃O⁺
Whereby HNO₃ is a strong acid and it undergoes complete ionization in an aqueous solution
Hence one mole of HNO₃ produces one mole of H₃O⁺ ions
0.0155 mol/L HNO₃ will have 0.0155 moles of H₃O⁺ in one liter of the solution
The concentration of hydronium ions = 0.0155 mol/L.
Answer:
1. False
2. False
3. True
4. False
Explanation:
1. CBr4 is more volatile than CCl4 False
The molecular weight of CBr4 is is greater than the CCl4, therefore it has less tendency to escape to the gas phase. Also, the CBr4 has greater London dispersion forces compared to CCl4 since bromine is a larger atom than chlorine.
2. CBr4 has a higher vapor pressure at the same temperature than CCl4 False
For the same reasons as above, the vapor pressure of CBr4 is smaller than the vapor pressure of CCl4
3. CBr4 has a higher boling point than CCl4 True
Again, CBr4 having a molecular weight greater than CCl4 ( 331 g/mol vs 158.2 g/mol) is heavier and less volatile with a higher boiling point than CCl4.
4. CBr4 has weaker intermolecular forces than CCl4 False
Both molecules are non-polar because the dipole moments in C-Cl and C-Br bonds cancel in the tetrahedron. The only possible molecular forces are of the London dispersion type which are temporary and greater for larger atoms.
