balancing equations Flashcards
1
Q
name the types of reactions
A
synthesis, decomposition, sr, dr, combustion, neutralization
2
Q
name the diatomic elements
A
H, N, O, F, Cl, Br, I
3
Q
what are the steps to balancing neutralization reactions
A
1) The # of Hs in the acid = the # of OHs in the base
2) However many Hs & OHs = same amount of H2O
3) Salt produced is made from le over ions (co‐
efficients in front become subscripts)
4
Q
what are the steps to balancing combustion reactions
A
1) Balance the Carbon
2) Balance the Hydrogen
3) Balance the Sulphur
4) Balance Oxygen LAST ‡ If # of O2 is ODD
mulply all co‐efficients by 2 to make it EVEN
5
Q
how can you tell if the reaction is combustion
A
a carbon compound reacng with
an O2
