Part A: Identify the following parts of each chemical formula by circling the subscripts and drawing a square around the coefficients.
H2 2 HCl 4 O2 CH4 3 CO3 2 NaOH
Part B: List the symbols for the atoms in each formula and give the number of each. C2H6 2MgO 4P4O10
NH3 3 Al(OH)3 2 H2O2
Part C: Balance each of the following equations following the procedure described in class. Be sure to show your work.
P + O2 â P4O10 Mg + O2 â MgO
P = P = Mg = Mg = O = O = O = O =
HgO â Hg + O2 Al2O3 â Al + O2
Hg = Hg = Al = Al = O = O = O = O =
BaCl2 + H2SO4 â BaSO4 + HCl
Ba = Ba =
Cl = Cl =
H = H =
S = S =
O = O =
