The molecule with higher dipole moment is COFH because the geometry of the molecule in the COF2 nearly cancel the dipolar moment of each other. To be more clear:
The dipolar moment is the vectorial sum of all bond moments in the molecule or dipolar moment of each bond. The dipolar moment of a molecule with three or more atoms is determined by bond polarity as their geometry.
COF2 has a trigonal planar structure which are symmetric. The electronegativity of oxygen is slightly different regarding fluor. So as you can see in the image, the electronic density is specially displaced to the fluor atoms, but either to the oxygen atom.
COFH has a trigonal structure but differs from COF2 because there is an hydrogen who is donating it's electronic density, so in this zone the electronic density is less than over oxygen or fluor. That makes bond angles be different between them.
Answer:
60 q
Explanation:
The conversion factor is 100; so 1 quintal = 100 kilograms. In other words, the value in q multiply by 100 to get a value in kg.
The characteristic of the compound you are referring is essential to where on the functional groups it belong. Furthermore, the basic functional groups among the hydrocarbons are: alkane, alkene, alkyne, benzene, and others that basically has a hydrogen atom and a carbon atom.
Answer:
1
The heat of reaction is
The enthalpy is
2
The concentration of HCl is
Explanation:
From the question we are told that
The volume of is
The number of concentration of is
The volume of HCl is
The number of concentration of is
The temperature difference is
Now the heat of reaction is mathematically represented as
Where
is the specific heat of water with value
Now
where is the molar mass of NaOH with the value of 0.04 kg/mol
So
While
Where is the molar mass of with the value of 0.03646 kg/mol
So
=>
The enthalpy is mathematically represented as
=>
From the second question we are told that
The volume of HCl is
The volume of NaOH is
The concentration of NaOH is
The first temperature change is
The second volume of
The mass of NaOH is
substituting values
The mass of the product formed is
substituting values
The multiplication by 1000 is to convert it from kg to grams
Now the mass of HCl is
substituting values
Now the concentration of HCl is
The multiplication of is to convert it from kg/mol to g/mol
There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
