The atomic radius of lithium is larger than the atomic radius of nitrogen.

Ulleksa [173]

Answer:

a. True

Explanation:

In the periodic table , all the elements are placed in a certain fashion , i.e. , with increasing atomic number.

Since ,

The element lithium and nitrogen are placed , in group 1 and 15 respectively.

as we go from left to right , across the group , the atomic radius decreases ,

Because ,

As , we go left to right , the number of electrons increases in the same shell , and proton too increases , which in turn increases the nuclear attraction , and the nucleus holds on to the electrons more firmly , and hence , the size reduces , as the electrons increases , in the same shell.

Hence, the given statement is true.

For the reaction, 2cr2+ + cl2(g) ---> 2cr3+ + 2cl- e cell (standard conditions) = 1.78v calculate ecell (standard conditions)

PolarNik [594]

Answer:

-1.78 V

Explanation:

There are several rules required to calculate the cell potential:

given standard cell potential, we may reverse the equation: the products of a given reaction become our reactants, while reactants become our products in the reversed equation. For a reversed equation, we change the sign of the cell potential to the opposite sign;
if we multiply the whole equation by some number, this doesn't influence the cell potential value. It only produces a different expression in the equilibrium constant.

That said, notice that the initial reaction with respect to the final reaction is:

reversed: chromium(III) cation and chloride anion become our reactants as opposed to the products in the initial reaction, so we change the sign of the cell potential to a negative value of -1.78 V;
each coefficient is multiplied by a fraction of $\frac{1}{2}$ . It doesn't influence the value of the cell potential.
