Why is the following equation invalid Al 2O2 --- Al2O3?
Because the numbers of aluminum and oxygen atoms are not the same on both sides of the equation, so the equation is not balanced. In order to be balanced, the numbers of atoms of each element must be the same on both sides of the equation. The correct equation is 4Al + 3O2 --> 2Al2O3. This gives 4 aluminum atoms and 6 oxygen atoms on both sides of the equation, so it is balanced.
What is the correct formula for Ca2 plus reacting with NO21-?
The correct balanced chemical equation for Ca^2+ reacting with NO2^1- is Ca^2+ + 2NO2^- -> Ca(NO2)2. This equation shows that one calcium ion reacts with two nitrite ions to form one molecule of calcium nitrite.
