Thus, on the left side of the equation, we need twice as much
_________________. On the right side of the equation, we need twice as much
_____________. In order to satisfy this requirement, the equation becomes
On each side of the equation, we now have (one) (two) calcium atoms(s), (one)
(two) hydroxide radical(s), (one) (two) hydrogen atoms, and (one) (two) (three)
nitrate radicals. Since we now have an equal number of each type of atom and
radical on both sides of the equation, we can say that the equation is
Sulfuric acid and ferric hydroxide react to produce ferric sulfate and water. The
equation without balancing is:
_________+________ ------> _________+________
Now, list the reactants and the products as in the previous exercise.
Now, balance the equation. (Before looking at the answer, be sure you have the
same number of each type of atom or radical on both sides of the equation.)
__H2SO4 + __ Fe (OH)3 ----> __Fe2(SO4)3 + __ HOH
Iron metal and sulfur react to yield ferrous sulfide. The balanced equation for this
reaction is ______________________________.
6. Sodium carbonate and hydrochloric acid react to yield sodium chloride, water, and
carbon dioxide gas. Use a piece of scratch paper to write the balanced equation.
The balanced equation is ________________________.
Did you forget the arrow after CO2? The arrow means that CO2 is given off as a
