In the lewis structure of ch3oh, how many bonding pairs of electrons are there?
zysi [14]
Answer:
            There are five <span>bonding pairs of electrons in Methanol.

Explanation:
                   Those electron pairs which are being shared between two atoms in molecule are called as bonding pair electrons. While, those electron pairs which are not involved in bond formation and are not shared between two atoms are called as Non-Bonding electron pairs.
                   In molecule of Methanol as shown below, it can be seen that carbon atom is forming four bonds with three hydrogen atoms and one oxygen atom by sharing four electron pairs and oxygen is forming two bonds, one with carbon atom and one with hydrogen atom. There are two lone pair of electrons present on oxygen atom which are not taking part in and formation.</span>

What is the change in enthalpy for the following reaction? 
Tju [1.3M]

The given chemical reaction is:

2H_{2}O_{2}(aq)---> 2H_{2}O(l)+O_{2}(g)

The standard heats of formation of H_{2}O and H_{2}O_{2} are:

ΔH_{f}^{0}(H_{2}O) = -285.8kJ/mol[/tex]

ΔH_{f}^{0}(H_{2}O_{2}) = -187.6 kJ/mol[/tex]

Calculating the change in heat:

ΔH^{0}_{reaction)=∑ΔH_{f}^{0}(products)-∑ΔH_{f}^{0}(reactants)

                         = [{2 * (-285.8 kJ/mol)} -{2*(-187.6 kJ/mol)}]

                          = -196.4 kJ/mol

Therefore, the change in enthalpy for the given reaction is -196.4 kJ/mol
