Snowcat [4.5K]

Oxygen dichloride molecule consists  of an oxygen atom and two chlorine atoms. According to the VSEPR theory, the 3-D shape of the compound is bent.

There are 6 valence electrons in the oxygen atom and each chlorine atom has 1 valence electrons. Therefore, there are 8 valence electrons or 4 pairs of valence electrons.

According to VSEPR theory, due repulsion between 4 pairs of valence electrons, bond angle between two O-Cl bonds becomes 110 degrees and the shape of the molecule of the compound becomes bent.

Sholpan [36]

Answer:

3.58J/g°C is the specific heat of the metal

Explanation:

The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:

Q = S*ΔT*m

<em>Where Q is energy = 1362J</em>

<em>S is specific heat of the material</em>

<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>

<em>And m is the mass of the material = 15.2g</em>

Replacing:

S = Q / ΔT*m

S = 1362J / 25°C*15.2g

<h3>3.58J/g°C is the specific heat of the metal</h3>
