242 g/mol...... hope it helps :)
Answer:
B
Explanation:
That electron is found in the 3d orbital.
ml=-2,-1,0,1,2
n=3
l=2
ml=0
ms=-1/2
Since it must be of opposite spin according to Pauli exclusion principle.
Answer: (a) The reaction mixture will proceed toward products.
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as ![K_p](https://tex.z-dn.net/?f=K_p)
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
![2A(g)\rightleftharpoons B(g)](https://tex.z-dn.net/?f=2A%28g%29%5Crightleftharpoons%20B%28g%29)
The expression for
is written as:
![Q_p=\frac{p_B}{(p_A)^2}](https://tex.z-dn.net/?f=Q_p%3D%5Cfrac%7Bp_B%7D%7B%28p_A%29%5E2%7D)
![Q_p=\frac{(2.0)}{(2.0)^2}](https://tex.z-dn.net/?f=Q_p%3D%5Cfrac%7B%282.0%29%7D%7B%282.0%29%5E2%7D)
![Q_p=0.5](https://tex.z-dn.net/?f=Q_p%3D0.5)
![K_p=0.76](https://tex.z-dn.net/?f=K_p%3D0.76)
Thus as
, the reaction will shift towards the right i.e. towards the product side.
B) loses electrons and is oxidised
Its oxidation number is 0 in Co(s) and +2 in Co(C2H302)2(aq), hence it gets oxidised
Answer:
b
Explanation:
because it is the simplest substance of all matters
