The meaning of 2 is two methane molecules.
The coefficient for water in a balanced chemical equation depends on the specific reaction being described. For example, in the combustion of methane, the balanced equation is: CH4 + 2O2 -> CO2 + 2H2O In this case, the coefficient for water is 2.
To balance the equation CH4 + H2O → H2 + CO, you need to change the coefficients. Start by balancing the carbon atoms - there is 1 carbon on each side so you can leave that as is. Next, balance the hydrogen atoms by adding a coefficient of 2 in front of H2 on the product side. Lastly, balance the oxygen atoms by adding a coefficient of 1 in front of H2O on the reactant side to give you CH4 + H2O → 2H2 + CO.
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2
The balanced chemical equation for the reaction CH4 + 2O2 → CO2 + 2H2O shows that 1 molecule of CH4 reacts with 2 molecules of O2 to produce 1 molecule of CO2 and 2 molecules of H2O. This equation ensures that the number of atoms of each element is the same on both sides of the reaction arrow.
Radical 2 is a number, it does not have a coefficient.
To balance CH4 + Cl2 = CCl4 + HCl, first balance the carbon atoms by putting a coefficient of 1 in front of CCl4. Next, balance the hydrogen and chlorine atoms by placing a coefficient of 4 in front of HCl and a coefficient of 2 in front of Cl2. The balanced equation is CH4 + 2Cl2 = CCl4 + 4HCl.
2X 2 is the coefficient
8 is the coefficient. A coefficient is the number in front of a variable.
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
A coefficient is a number before a variable. For example, in 2x, the 2 would be the coefficient
In the term 2p, 2 is the coefficient.
3 CH4 + 5 O2 ----> 2 CO + CO2 + 6H2OThe reaction generates quantities of carbon monoxide along with carbon dioxide and water.
