Answer:
Equilibrium constant of the given reaction is ![1.3\times 10^{-29}](https://tex.z-dn.net/?f=1.3%5Ctimes%2010%5E%7B-29%7D)
Explanation:
....![(K_{p})_{1}=5.3](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B1%7D%3D5.3)
....![(K_{p})_{2}=2.1\times 10^{30}](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B2%7D%3D2.1%5Ctimes%2010%5E%7B30%7D)
The given reaction can be written as summation of the following reaction-
![2NO+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=2NO%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
![N_{2}+O_{2}\rightleftharpoons 2NO](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%5Crightleftharpoons%202NO)
......................................................................................
![N_{2}+O_{2}+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
Equilibrium constant of this reaction is given as-
![\frac{[NOBr]^{2}}{[N_{2}][O_{2}][Br_{2}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNOBr%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%5BBr_%7B2%7D%5D%7D)
![=(\frac{[NOBr]}{[NO][Br_{2}]^{\frac{1}{2}}})^{2}(\frac{[NO]^{2}}{[N_{2}][O_{2}]})](https://tex.z-dn.net/?f=%3D%28%5Cfrac%7B%5BNOBr%5D%7D%7B%5BNO%5D%5BBr_%7B2%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%29%5E%7B2%7D%28%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%7D%29)
![=\frac{(K_{p})_{1}^{2}}{(K_{p})_{2}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%28K_%7Bp%7D%29_%7B1%7D%5E%7B2%7D%7D%7B%28K_%7Bp%7D%29_%7B2%7D%7D)
![=\frac{(5.3)^{2}}{2.1\times 10^{30}}=1.3\times 10^{-29}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%285.3%29%5E%7B2%7D%7D%7B2.1%5Ctimes%2010%5E%7B30%7D%7D%3D1.3%5Ctimes%2010%5E%7B-29%7D)
The elements combine with other elements in order to complete their octet and attain stability. The combination can take place either by transfer of electrons or by sharing of electrons. The sharing of electrons results in formation of covalent bond whereas transfer of electrons results in the formation of ionic bonds. The loss of electrons will result in the formation of cation whereas the gain of electrons results in formation of anion. The two oppositely charged ions are held together by electrostatic force of attraction between them.
Hence, an ionic is a force that holds two oppositely charged ions together.
Answer:A
Explanation:
A nuclear reaction is balanced by ensuring that the Masses and charges of te reactants and products are exactly balanced on the left and right hand side of the reaction equation. If there are 60 mass units on the LHS and manganese has only 56 mass units then four mass units are left. If there is no charge on a neutron and there is a charge of 27 on the cobalt, then two charges are left. Four mass units and a charge of +2 corresponds to a helium which is actually an alpha particle.
Answer is: 4,4 grams <span>of carbon dioxide gas would be produced.
</span>Chemical reaction: CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O.
m(CaCO₃) = 10 g.
n(CaCO₃) = 10 g ÷ 100 g/mol.
n(CaCO₃) = 0,1 mol.
From chemical reaction: n(CaCO₃) : n(CO₂) = 1 : 1.
n(CO₂) = 0,1 mol.
m(CO₂) = n(CO₂) · M(CO₂).
m(CO₂) = 0,1 mol· 44 g/mol.
m(CO₂) = 4,4 g.
