Balanced Chemical Equations Only Show Formulae, Not Names.

(a) fe+ cl2 −−→ fecl3 (b) fe+ o2 −−→ fe2o3 (c) febr3 + h2so4 −−→ fe2(so4)3 + hbr (d) c4h6o3 + h2o −−→ c2h4o2 (e) c2h4 + o2 −−→ co2 + h2o (f) c4h10o+ o2 −−→ co2 + h2o (g) c7h16 + o2 −−→ co2 + h2o (h) h2sicl2 + h2o −−→ h8si4o4 + hcl (i) hsicl3 + h2o −−→. A = mg, b = mgo. 3fe + 4h2o = fe2o4.

The Answer Will Appear Below;

The first step to balance the equation is to write down the chemical formula of reactants that are listed on the left side of the chemical equation. Calculate the number of atoms of each element in the reaction (both sides) i. This burns with oxygen (o2) to form carbon dioxide (co2) and water (h2o) the unbalanced chemical equation can be written as.

After This, You Can List Down The Products On The Right Hand Side Of The Chemical Equation.
