When asked to balance the equation: C2H6 + O2 = CO2 + H2O the following suggestions were made: C2H6 + 5O2 = 2CO2 + 3H2O C2H6 + 5O = 2CO + 3H2O 2C2H6 + 7O2 = 4CO2 + 6H2O Which answer is correct and what is wrong with the others?

    the number of each atom must be equal on each side of the equation remember law of conservation of mass

    @15Twilight follow this to see whether an equation is balanced make a chart. and count up the number of each atom in both the reactants and the products. C2H6 + O2 = CO2 + H2O |dw:1443491750022:dw| based of of this is the equation balanced?

    we need to balance this now, this takes time and there's no real i guess strategy you just have to try your best to put coefficients infront of the reactants+ products to balance them.

    C2H6 + 4O2 = 2CO2 + 3H2O

    2 atoms of carbon 6 atoms of hydrogen, 8 atoms of oxygen products: 2 atoms of carbon 4 atoms of oxygen, and 6 atoms of hydrogen ..am I right?
