Answer: 6.98
The Relative Atomic Mass of Li = (98*7 + 2*6)/98+2
RAM of Li = (686+12)/100
RAM of Li= 6.98
The square brackets are used in case of complex compounds. This is known as coordination sphere. There is a metal in the coordination sphere and ligands attached to it. This complete set of metals and ligands inside the brackets is complex ion or molecule.
The ions outside this coordination sphere are counter ions of the complex.
It represents that if the complex compound is dissolved in water it will give a complex ion and the counter ion. The atoms in the bracket cannot break there bonds and will remain un-dissociated.
If there is no such bracket then it will represent simple or binary salt.
Answer:
The Equilibrium will shift towards the left.
Explanation:
The reaction for the formation of nitric oxide is follows,
Expression for reaction quotient is as follows,
![Q=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Putting the values according to the data given and calculating reaction quotient for the reaction
So, the reaction quotient is 0.16.
and the value of K is 0.01 .
Q>K
Since the value of K is less than Q, therefore the reaction will shift towards left.
