In one experiment, the reaction of 1.00 mercury and an excess of sulfur yielded 1.16g of a sulfide of mercury
Nuetrik [128]

<u>Answer and Explanation:</u>

Mercury combines with sulfur as follows -

Hg + S = HgS

Hg = 200,59

S = 32,066 Therefore 1.58 g of Hg will react with -

1.58 multiply with 32,066 divide by 200,96 of sulfur.

= 0.25211 g S

This will form 1.58 + 0.25211 g HgS  = 1.83211 g HgS

The amount of S remaining = 1.10 - 0.25211  = 0.84789 g

Determine the electron-group arrangement, molecular shape, and ideal bond angle(s) for each of the following:
lubasha [3.4K]

Solution :

a). $SO_3$

  This compound is known as sulfur trioxide.

  The molecular shape of sulfur trioxide is trigonal planer.

   And the bond angle is 120°.

b). $N_2O$

   This compound is known as Nitrous oxide. Here, nitrogen is in the center.     There is no lone pair around the nitrogen atom and it forms two sigma bonds with the other two atoms.

 It is linear in shape.

  The bond angle between them is 180°.

c). $CH_2Cl_{2}$

  This compound is known as the Dichloromethane.

   The molecular shape of the compound is tetrahedral.

   The bond angles is 120°
