Answer:
The electronengativity values of given elements is as follows.
Fluorine - 4
Chlorine -3
Bromine - 2.9
Iodine- 2.5
Explanation:
Electronegativity =consant (I.E-E.A)
The electron affinity and ionization energy values of the given elements is as follows.
(In attachment)
First we have to find the value of constant by using the fluorine atom to whom the electronengativity taken as "4".
<u>Fluorine:</u>
![4=constant[1678-(-327.8)]](https://tex.z-dn.net/?f=4%3Dconstant%5B1678-%28-327.8%29%5D)
By using this constant values we can find electronegatvity values of remaining elements.
<u>Chlorine:</u>
![Electronegativity=0.0019942168[1255+348.7]=3.1980\sim 3](https://tex.z-dn.net/?f=Electronegativity%3D0.0019942168%5B1255%2B348.7%5D%3D3.1980%5Csim%203)
Therefore, electronegativity of chlorine is 3.
<u>Bromine:</u>
![Electronegativity=0.0019942168[1138+324.5]=2.91\sim 2.9](https://tex.z-dn.net/?f=Electronegativity%3D0.0019942168%5B1138%2B324.5%5D%3D2.91%5Csim%202.9)
Therefore, electronegativity of bromine is 2.9.
<u>Iodine:</u>
![Electronegativity=0.0019942168[1007+295.7]=2.59\sim 2.5](https://tex.z-dn.net/?f=Electronegativity%3D0.0019942168%5B1007%2B295.7%5D%3D2.59%5Csim%202.5)
Therefore, electronegativity of iodine is 2.5.
Answer:
Molarity = 0.13M
Explanation:
n=m/M = 4.87/74.55= 0.065mol, V= 500ml= 0.5dm3
Applying
n= C×V
0.065= C×0.5
C= 0.13M
<span>Carbonic acid is a chemical compound with the chemical formula H₂CO₃. It is also a name sometimes given to solutions of carbon dioxide as it contains water. It affects the rock by a process. When water meets carbon-dioxide in the air, a weak solution occurs called "CARBONIC ACID" and when it meets the crack of the rock, it diffuses and it ti dissolve with it. HOPED THIS HELPS YOU :)</span>
The answer for this question would be when we increase the temperature of a particular object, its molecules get energy in that specific reaction takes place more quickly and if we decrease the temperature the reverse of what will happen to that thing.
The two factors that are mainly responsible for determining the thermal energy of a substance are Temperature and Mass.
<h3><u>Explanation:
</u></h3>
Thermal energy is the total energy of the substance.
Temperature: The temperature and thermal energy of a substance are directly related to each other(direct proportion) which means that the greater the temperature, the greater will be the thermal energy of that particular substance.
Mass: Consider a situation, if we have two or more substances that have the same temperature the substance with the highest mass will have the most thermal energy than the others.
