AQA Chemistry Unit 1 - [23rd May 2014]AM

who wants to tell me equation/crap i need to know around "know that combustion of hydrocarbons containing sulfur leads to sulfur dioxide that causes air pollution and understand how sulfur dioxide can be removed from flue gases using calcium oxide"

Hope i come out with an A....My maths exams dont look too well.....really wanted an A but im gonna end up with a B and retaking in yr 13....so all for the best

Basically, in any complete combustion of a hydrocarbon, you always get water and carbon monoxide. ALWAYS.
So with a sulfur-containing hydrocarbon, oxygen reacts with the S to form sulfur dioxide.

Now, this sulfur dioxide is quite acidic, so it contributes acid rain. To neutralize it, you need a base, such as calcium oxide. They place calcium oxide in chimneys of some factories to remove the gas. That's pretty much it I think!

To simplify things,

One car(carbon) is joined to 3 other cars(carbon). Each car has one person(hydrogen) in it.
4 cars, 4 people. 1:1ratio

Hey is there a simple way to figure out the number of isomers for a hydrocarbon? Trial and error never works for me, but I wasn't really taught a method oops

Any help massively appreciated

How do you calculate enthalpy of a simple reaction? is it products-reactants or reactants-producs?

im so confused it doesn't have a shape its just one ion its like a ball that has lost 3 electrons.... right?

In complete combustion you get water and carbon dioxide.
In incomplete you get water and carbon/carbon monoxide.

oh i get it now not Cl(3+) but (Cl3)+ um its Cl with two bonding pairs so Cl----Cl----Cl but theres two lone pairs so it becomes like water? maybe?
which is bent line/ V-shaped
