The balanced equation for the reaction of potassium with oxygen is: 4K + O2 -> 2K2O The coefficient of oxygen in this balanced equation is 1.
The balanced equation for the combustion of heptane is: C7H16 + 11 O2 -> 7 CO2 + 8 H2O. Therefore, the coefficient for oxygen is 11.
This chemica equation is:B2H6 + 3 O2 = B2O3 + 3 H2O
To balance this chemical equation, start by balancing the sulfur atoms: add a coefficient of 2 in front of H2O to balance the sulfur atoms. Next, balance the hydrogen atoms by adding a coefficient of 2 in front of H2S. Finally, balance the oxygen atoms: add a coefficient of 3 in front of O2 to balance the oxygen atoms on both sides. The balanced equation is 2H2S + 3O2 → 2H2O + 2SO2.
The balanced equation for the decomposition of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2) is 2H2O2 → 2H2O + O2. Therefore, the correct coefficient before H2O is 2.
The balanced equation for the reaction of potassium with oxygen is: 4K + O2 -> 2K2O The coefficient of oxygen in this balanced equation is 1.
The coefficient for oxygen is 1, and so is not written. The equation is already balanced.
what is the chemical equation of nitrogen + oxygen= nitric oxide
This chemica equation is:B2H6 + 3 O2 = B2O3 + 3 H2O
The balanced equation for the complete combustion reaction is 2 C3H7OH + 9 O2 -> 6 CO2 + 4 H2O; therefore, the coefficient for oxygen is 9. If fractional coefficients are allowed, the equation can be written with only one mole of C3H7OH; in that instance the coefficient for oxygen would be 9/2.
The balanced equation for the combustion of heptane is: C7H16 + 11 O2 -> 7 CO2 + 8 H2O. Therefore, the coefficient for oxygen is 11.
4K + O2 --> 2K2O The coefficient of oxygen is 1 but, 1 is understood and never written as a coefficient.

2KClO3 ----> 2KCl + 3O2
apex sometimes the coefficient for the oxygen molecule is not a whole number.
apex sometimes the coefficient for the oxygen molecule is not a whole number.
The formula still means oxygen, it's just that the coefficient in the front means that there are 6 more oxygen atoms in the equation, but they are not being used for now.
