Calculate the ratio of the mass ratio of SS to OO in SOSO to the mass ratio of SS to OO in SO2SO2. Consider a sample of SOSO in

Veronika [31]

Answer:

The ratio of the mass ratio of S to O; in SO, to the mass ratio of S to O; in SO₂, is 2:1

Explanation:

According to the consideration, let us first find the ratio of S and O in both the compounds

For SO:

$\frac{m_{S} }{m_{O} }= \frac{32}{16}\\\\ \frac{m_{S} }{m_{O} }= 2$

Let us express it as

$SO_{\frac{m_{S} }{m_{O} }} = 2$

For SO₂,

Due to two oxygen atoms in the molecule, the mass of oxygen will be taken two times

$\frac{m_{S} }{m_{O} }= \frac{32}{(2)(16)}\\\\ \frac{m_{S} }{m_{O} }= 1$

Let us express it as

$SO_2_{\frac{m_{S} }{m_{O} }}= 1$

Now, for the ratio of both the above-calculated ratios,

$\frac{SO_{\frac{m_{S} }{m_{O} }}}{SO_2_{\frac{m_{S} }{m_{O} }}}=\frac{2}{1}$

The required ratio is 2:1

Phosphorus oxychloride has the chemical formula POCl3, with P as the central atom. In order to minimize formal charge, how many

Elina [12.6K]

Answer:

Phosphorus makes 5 bonds with other atoms

Explanation:

$POCl_{3}$ has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).

These valence electrons are used to draw Lewis structure of $POCl_{3}$ .

Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)

Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of $POCl_{3}$ , it has been found that P makes total 5 bonds with rest of the atoms.

Lewis structure of $POCl_{3}$ along with formal charge (in parentheses) has been given below.
