Answer:

176.5 picometer is the bond length of a C-Cl bond.

Explanation:

Bond length of chlorine molecule = 199pm

Radius of the chlorine atom = r_{Cl}=\frac{199 pm}{2}

Bond length of carbon molecule = 154 pm

Radius of the carbon atom = r_c=\frac{154 pm}{2}

Bond length of C-Cl =

r_c+ r_{Cl}=\frac{154 pm}{2}+\frac{199 pm}{2}=176.5 pm

176.5 picometer is the bond length of a C-Cl bond.

How many kilojoules are released when 8.2 g of water condenses at 100 °c and cools to 15 °c?
MrRa [10]

Answer:- 2.92 kJ of heat is released.

Solution:- We have water at 100 degree C and it's going to be cool to 15 degree C.

So, change in temperature, \Delta T = 15 - 100 = -85 degree C

mass of water, m = 8.2 g

specific heat of water, c = 4.184\frac{J}{^0C.g}

The equation used for solving this type of problems is:

q=mc\Delta T

Let's plug in the values in the equation and solve it for q which is the heat energy:

q = (8.2)(4.184)(-85)

q = -2916.248 J

They want answer in kJ. So, let's convert J to kJ and for this we divide by 1000.

q=-2916.248J(\frac{1kJ}{1000J})

q = -2.92 kJ

Negative sign indicates the heat is released. So, in the above process of coiling of water, 2.92 kJ of heat is released.

How many Mg atoms are presented in 3.00 moles of MgCl2
ella [17]

Answer:

1.81 x 10²⁴ atoms

Explanation:

To find the number of atoms in the given number of moles, we need to understand that every substance contains the Avogadro's number of particles.

More appropriately, a mole of any substance will contain the Avogadro's number of particles which is 6.02 x 10²³ atoms

 So;

           If 1 mole of a substance  = 6.02 x 10²³ atoms;

               3 mole of MgCl₂ will contain 3 x 6.02 x 10²³ = 1.81 x 10²⁴ atoms
