They are more attracted by the oxygen atom than by the hydrogen atom.
Explanation:
In the polar bond of water which is made up of hydrogen and oxygen atoms, the shared electrons are more attracted by the oxygen atom than by the hydrogen atom.
The interatomic bond in water is a polar covalent bond.
In this bond type, two species shares their valence electrons.
The bond usually occurs between non-metals with an electronegativity difference that is small.
Oxygen is more electronegative compared to hydrogen.
- This implies that oxygen pulls the electron more closely to itself since it has a greater affinity.
- This leaves a partial negative charge on oxygen and a positive charge on hydrogen.
- The molecule is said to be polar covalent.

Answer:
a
No
b
100 mm Hg
Explanation:
From the question we are told that
The vapor pressure of CHCl3, is 
The temperature of CHCl3 is 
The volume of the container is 
The temperature of the container is 
The mass of CHCl3 is m = 0.380 g
Generally the number of moles of CHCl3 present before evaporation started is mathematically represented as
Here M is the molar mass of CHCl3 with the value 
=> 
=> 
Generally the number of moles of CHCl3 gas that evaporated is mathematically represented as
Here R is the gas constant with value 
So
Given that the number of moles of CHCl3 evaporated is less than the number of moles of CHCl3 initially present , then it mean s that not all the liquid evaporated
At equilibrium the temperature of CHCl3 will be equal to the pressure of air so the pressure at equilibrium is 100 mmHg
Answer:
21 g/mL
Explanation:
To solve this problem, first look at the density equation, which is D=M/V, which D stands for density, M stands for mass, and V stands for volume. When you substitute in the variables, you get D=17.5/.82, which is equivalent to 21.34. However, since we need to pay attention to the sig fig rules for multiplying, we need to have the same amount of sig figs as the value with the least amount of sig figs, which is the number .82. .82 has two sig figs, so you round down. Your answer will be 21 g/mL.
