a compound containing 3 atoms of carbon and 8 atoms ofhydrgen is combined in a reaction with oxegyn molecules the two end products of this equation are carbon dioxide co 2 and water what elemement should i look at first in balancing this equation oxygen hydrgen carbon or dioxide and wen finished balancing this which chemical or element will have the largest no of molecules the ch3 the oxygen carbon dioxide or water
To balance the equation, you should start by looking at the elements individually. In this case, there are four elements involved: carbon (C), hydrogen (H), oxygen (O), and dioxide (O2).
The first step is to balance the carbon atoms. Since there are three carbon atoms on one side and only one carbon atom on the other side, you need to place a coefficient of 3 in front of the CO2 molecule on the product side, making it 3CO2.
Next, you can focus on balancing the hydrogen atoms. There are eight hydrogen atoms on the reactant side, but only two hydrogen atoms on the product side (from the water molecule). To balance the hydrogen atoms, you need to place a coefficient of 4 in front of the H2O molecule on the product side, making it 4H2O.
Now you can move on to balancing the oxygen atoms. There are three oxygen atoms on the reactant side (from the O2 molecule), and three oxygen atoms in the CO2 molecule on the product side. Since the oxygen atoms are already balanced, you don't need to make any changes.
Finally, you have balanced the equation:
CH3 + O2 -> 3CO2 + 4H2O
Regarding the chemical or element with the largest number of molecules, you need to look at the coefficients in front of each molecule. In this balanced equation, the coefficient in front of CO2 is 3, which means you have three molecules of carbon dioxide. The coefficient in front of H2O is 4, which means you have four molecules of water. Therefore, the chemical or element with the largest number of molecules is water (H2O) with four molecules.
