Concept explainers
Interpretation:
The oxidation state of the carbon atom that is highlighted in the given atom has to be calculated.
Concept Introduction:
Oxidation state of an element is the total number of valence electron that it loses or gains to attain the stable octet structure.
To calculate the oxidation state of carbon atom, we treat all the bonds to be ionic. This means that the more electronegative atom will have the two electrons that is been shared with itself. An example for finding the oxidation state of carbon atom is given below,
By treating all the bonds as ionic, we find that the two electrons are given to chlorine atom. Between carbon and hydrogen, the two electrons are given to the carbon atom as carbon is slightly more electronegative than hydrogen atom. The electrons present between the carbon and carbon is shared equally because they are same. This gives the carbon atom to have five electrons around it.
We know that the valence electrons of carbon is four. In this case it has got one extra electron. Therefore, the oxidation state of this carbon atom can be said as “-1”.

- Need help understanding please help Let’s assume the initial volume of the gas is 4.80 LL , the initial temperature of the gas is 29.0 °C°C , and the system is in equilibrium with an external pressure of 1.2 bar (given by the sum of a 1 bar atmospheric pressure and a 0.2 bar pressure due to a brick that rests on top of the piston). What is the final pressure of the gas? What is the final volume of the gas? What happens with the piston after you finish heating the gas? Assume you do not need to worry about the gas cooling down again because the outside of the container is at a lower temperature.
