(d) What is the molarity of MCIO3 in Solution A? 2. Use the identity of MCIO3 and the decomposition equation above to answer the following questions: (a) Calculate the enthalpy of formation (AH) of MCI. (b) If you performed the decomposition reaction of Solution A in a coffee-cup calorimeter, what would be the final temperature of the solution if the initial temperature was 25.0 °C? Assume cal = 0 and that the specific heat and densities of the solution are the same as that of water. AHf of MCIO3, next page.
Types of Chemical Bonds
The attractive force which has the ability of holding various constituent elements like atoms, ions, molecules, etc. together in different chemical species is termed as a chemical bond. Chemical compounds are dependent on the strength of chemical bonds between its constituents. Stronger the chemical bond, more will be the stability in the chemical compounds. Hence, it can be said that bonding defines the stability of chemical compounds.
Polarizability In Organic Chemistry
Polarizability refers to the ability of an atom/molecule to distort the electron cloud of neighboring species towards itself and the process of distortion of electron cloud is known as polarization.
Coordinate Covalent Bonds
A coordinate covalent bond is also known as a dative bond, which is a type of covalent bond. It is formed between two atoms, where the two electrons required to form the bond come from the same atom resulting in a semi-polar bond. The study of coordinate covalent bond or dative bond is important to know about the special type of bonding that leads to different properties. Since covalent compounds are non-polar whereas coordinate bonds results always in polar compounds due to charge separation.

a. Number of moles of O2 = 0.0613 mol
b. Number of moles of MClO3= 0.040836 mol
c. The Molar mass is 122.44 g/mol , The mystery substance is KClO3
![You found a container with a white substance labeled MClO₃ but you do not know which Group 1 metal M represents. You decide to use your chemistry wizardry to identify this mystery substance. You dissolve 5.00 g in enough water to produce 250. mL of the solution (Solution A). You decompose the chlorate according to the following reaction:
\[ 2MClO₃ \, (aq) \rightarrow 2MCl \, (aq) + 3O₂ \, (g) \quad \Delta H_{rxn} = -140.2 \, \text{kJ} \]
1. You collect the O₂ produced and it has a volume of 1.53 L at a temperature of 25.0 °C and 0.980 atm.
