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°

What is the specific heat of the solid phase? (Please see picture attached)
ValentinkaMS [17]

Answer:

B.0.2 J/g°C

Explanation:

From the attached picture;

  • Heat attained in the solid phase is 200 Joules
  • Change in temperature is 50°C ( from 0°C to 50°C)
  • Mass of the solid is 20 g

We are required to determine the specific heat capacity of the substance;

  • We need to know that Quantity of heat is given by the product of mass,specific heat capacity and change in temperature.
  • That is; Q = mcΔT

Rearranging the formula;

c = Q ÷ mΔT

Therefore;

Specific heat = 200 J ÷ (20 g × 50°c)

                      = 0.2 J/g°C

Thus, the specific heat of the solid is 0.2 J/g°C
