Answer:
An ionic bond is the bonding between a non-metal and a metal, that occurs when charged atoms (ions) attract.
Explanation:
Here I put the function of Iconic Bond.
- <em>Ionic bonds form so that the outermost energy level of atoms are filled. Ion. an atom or group of atoms that bring out a positive or negative electric charge as a result of having lost or gained one or more electrons.</em>
<em>Therefore, I hope this helps!</em>
Answer:
Elements in same group have same chemical properties due to same number of valence electrons in valence shell.
Explanation:
Chemical properties are those properties which results in transforming the starting material to a entirely new substance with different chemical and physical properties. This transformation takes place after a chemical reaction. Hence, the chemical reactivity of some atoms is greater than the others and vice versa.
In periodic table it is found that the elements in the same group have almost same chemical behaviour. For example, elements of group 8 (or 18) are almost non reactive, while that of group 1 and group 7 are found very reactive and show same chemical behaviour like group 1 elements forms +1 ion while group 7 elements form -1 ions as the group 1 metals have single valence shell electron which upon losing allow the atom to attain stability and the halogen having 7 electrons in valence shell upon accepting one electron allow them to attain a octet of stability respectively.
<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm
<u>Explanation:</u>
For the given chemical equation:
The expression of 
for above equation follows:
We are given:
Equilibrium partial pressure of 
= 0.0159 atm
Equilibrium partial pressure of NOBr = 0.0768 atm
Putting values in above equation, we get:
Hence, the equilibrium partial pressure of NO is 0.0034 atm
The new volume of the balloon : V₂ = 4.89 L
<h3>Further explanation</h3>
Given
V₁ = 4.96 L
T₁ = 6 + 273 = 279 K
T₂ = 2 + 273 = 275 K
Required
The new volume
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
V₂=V₁.T₂/T₁
V₂ = 4.96 x 275 / 279
V₂ = 4.89 L
