I Can't Be Asked to balance equations

 #GCSE #Chemistry CBA Can't Be Asked to balance chemical equations. The students seem to find this easy to remember and do and it works. #iteachchemistry #STEM #Science First the student writes down the equation with the correct formula. Sometimes we need to see that something like a carbonate is the same at the beginning and end, then they draw out a grid. Chemical, Before and After CBA

They write down each chemical in the equation and then write down the number of atoms of each.
Then they balance, If there are two Fluorine atoms at the beginning then there must be two at the end. They then rebalance the equation until its done.
