Write an equation for the formation of polyethene from ethene

It is a saturated hydrocarbon that has no double bonds in its structure. The two carbon atoms are bonded to each other through a covalent bond.

Write an equation for the formation of polyethene from ethene

The enthalpy of a given chemical reaction is constant, regardless of the reaction happening in one step or many steps.

There is a second way to use Hess' Law and it is usually presented like this: I'll explain the above equation using an example problem.

Calculate the standard enthalpy of combustion for the following reaction: It is so common that the phrase "standard enthalpy of combustion" is used alot and is given this symbol: The key to solving this problem is to have a table of standard enthalpies of formation handy.

In case you missed it, look at the equation up near the top and see the subscripted f.

What we are going to do is sum up all the product enthalpies of formation and then subtract the summed up reactant enthalpies of formation. Also, we need to have the equation balanced, so be sure to remember to check for that. Fractional coefficients are OK.

Since oxygen is an element in its standard state, its enthalpy of formation is zero. Textbooks which teach this topic will have an appendix of the values. Make sure you find it and figure out how to use it. If you are not too clear on what the term "standard enthalpy of formation" means, please look here.Mar 11,  · This Site Might Help You.
