The balanced equation is: C5H12 + 8O2 → 5CO2 + 6H2O. Therefore, the coefficient for oxygen in the balanced equation is 8.
1 nh3+ 2o2 >>>>> 1hno3 + 1h2o
The balanced chemical equation for the reaction is: 4Li + O2 -> 2Li2O The coefficient for lithium is 4.
2NaNO3 ==> 2NaNO2 + O2
The balanced symbol equation for carbon plus oxygen yielding carbon dioxide is: C + O2 -> CO2
The coefficient in front of the compound HgO in the formula 2HgO is 2. This means there are 2 moles of HgO for every 2 moles of the whole compound.
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.
Since the ratio of potassium to oxygen is 2:1 in the compound, the coefficient of oxygen in the balanced equation would be 1. The balanced equation for the reaction of potassium with oxygen to form this oxide would be 4K + O2 -> 2K2O.
1 nh3+ 2o2 >>>>> 1hno3 + 1h2o
The balanced chemical equation for the reaction is: 4Li + O2 -> 2Li2O The coefficient for lithium is 4.
The balanced equation is 4LiNO3(s) -> 4LiNO2(s) + 2O2(g). Therefore, the coefficient of oxygen gas (O2) is 2.
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 chemical equation H2 + O2 -> H2O is not balanced because the number of oxygen atoms is not equal on both sides of the equation. There are two oxygen atoms on the left side (O2) and only one on the right side (H2O). Balancing the equation would require adding a coefficient of 2 in front of H2O to have an equal number of oxygen atoms on both sides.
2NaNO3 ==> 2NaNO2 + O2
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.
This chemica equation is:B2H6 + 3 O2 = B2O3 + 3 H2O
The balanced symbol equation for potassium and oxygen is: 4K + O2 -> 2K2O
