Bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter
nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. given that the atomic radii of h and cl are 25.0 cm and 100. pm , respectively, predict the bond length of the hcl molecule.

Answer:Hence, the bond length in HCl is 125 pm.
Explanation:
Bond length : It is an average distance between the nuclei of two bonded atoms in a molecule.
Also given that bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter-nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Beyond this if atoms come closer to each other then their will be repulsion between them.
So, the bond length between the Hydrogen and Chlorine atom in HCl molecule is :
Hence, the bond length in HCl is 125 pm.

Answer:
M = 0.177
Explanation:
First, we have to find the molar mass of potassium iodine (KI).
K = 39.098
I = 126.904
Now, add these values together to get the molar mass of KI
39.098 + 126.904 = 166.0028
Now, it's time to do a grams to moles conversion.
35.0 g KI * =
= 0.212 mol KI
Now, we can find the molarity of this solution.
Molarity (M) =
M = = 0.177 M
The molarity (M) of this solution is 0.177.
