More Reaction Types

WHAT? MORE?!??! WHY OH WHY GOD HAVE YOU FORSAKEN ME!!?!?!

So yeah, looks like there are more of these to cover. None of which are new at all, so no need for the over dramatization.

Double Replacement

This is the Double Replacement reaction you know:
K2SO4 + BaCl2 ---> 2 KCl + BaSO4

Now here is that same reaction with the whole mess of crap that was added this year:

K2SO4(aq) + BaCl2(aq) ---> 2 KCl(aq) + BaSO4(s)

K(aq) + SO4(aq) + Ba(aq) + Cl(aq) ---> K(aq) + Cl(aq) + BaSO4(s)

Ba(aq) + SO4(aq)  ---> BaSO4(s)

As you may notice we have 3 separate equations. All of them however are essentially the same thing. The topmost is the balanced formula equation. (aq) determines that the item is aqueous while (s) determines that it is solid. To determine whether an item is aqueous or solid, use the table of solubility (all reactants are aqueous). The middle equation would be the Total Ionic Equation. To obtain this, separate all parts of the equation into individual elements or polyatomics, ignoring the coefficients. Items that are not aqueous cannot be separated. The last one is the net ionic equation which is obtained by cancelling items on either side of the total ionic equation like an algebraic equation.

Table of solubility

Combustion


This reaction consists of a chemical reacting with oxygen.

For hydrocarbons, the products will always include carbon dioxide and water
CH4(g) + 2 O2(g) ---> CO2(g) + 2 H2O(l)

For certain metals, the product will resemble a synthesis-like reaction
2 Fe(s) + O2(g) --> 2 FeO(g)

Neutralization


This reaction includes an acid + base as reactants and a salt + water as products. To form the salt take the chemicals that are not H or OH in the reactants and combine them in a synthesis like matter.

2 KOH(aq) + H2SO4(aq) ---> K2SO4(aq) + 2 H2O(l)


Thus conclude todays presentation. AND NOW FOR A VIDEO

Some nameless, faceless broad conducts a double replacement reaction in the name of SCIENCE. enjoy
