Answer:
10 hectometers
Explanation:
it equals 1000 meters not 100
For SiS₂, silicon disulfide, the electron dot formula could be seen in the attached picture. The total nonbonding electron pairs in a SiS₂ molecule is: 4 pairs.
<h3>What are the Lewis structure and nonbonding electron?</h3>
The electron dot formula, also known as the Lewis structure, is a representation of the total valence electrons of atoms within a molecule. By writing an electron dot formula, we can visualize the existence of valence electrons and whether they are within bonds or just stand as lone pairs.
The nonbonding electron or the lone pairs are electrons within an atom that are not forming a bond with the other atoms in a molecule. In the SiS₂ molecules, the 4 nonbonding pairs exist both in S atoms.

Answer:
Density of Radon is 5.44 g/.
Explanation:
Given data:
Temperature of gas = 100°C (273+100 = 373 K)
Pressure of gas = 0.75 atm
Density of gas = ?
Solution:
First of all we will derive the formula.
We know that,
PV = nRT
and
n = m/M (m = mass, M = molar mass)
PV = (m/M) RT
PVM = (m/M) RT ×M
PVM = mRT
PVM/V = mRT/V
PM = dRT (m/V = d)
Now we will put the values in formula:
Molar mass of Radon is 222 g/mol .
0.75 atm ×222 g/mol = d× 0.0821 atm.L/mol.K ×373 K
166.5 atm.g/mol = d×30.62 atm.L/mol
d = 166.5 atm.g/mol / 30.62 atm.L/mol
d = 5.44 g/L
