Balanced Equations

K so we went over all the stuff about balanced equations that we were talking about before the break. Not many notes for this class, just a lot of examples so ill use some of the notes from last year to supplememnt.

steps to balancing:

• first we must make sure the equation is correct

Mg + O2 - MgO

• balance the equation so there are the same amount of atoms on each side

2Mg + O2 - 2MgO

here are some acids that me are going to have to remember for the acid neutralization reactions:

• HCl: hydrochlroic acid
• HNO3: nitric acid
• H2SO4: sulphuric acid
• H3PO4: phosphoric acid
• CH3COOH: acetic acid

k so this video is pretty long but it gets the point across so s'all good :P

thats pretty much all we did today. ttfn!
