_____C2H6(g) + _____O2(g) ---> _____H2O(g) + _____CO2(g) - pleasee help me know how to balance equations?
Answer:
All you have to do is be sure there is the same amount of the same atom on both sides of the arrow. Law of Conversation of Mass. It just takes a lot of counting and patience.
2 C2H6 + 7 O2 ==> 6 H2O + 4 CO2
I hope no one answers this for you with the numbers. Look at it this way: You have to conserve mass. Take Carbon. The ratio of the number (moles) of C2H6 to CO2 has to be 1 mole of C2H6 to 2 moles of CO2 or carbon will not be preserved. Likewise you have to have three times as many moles of H2O as you do C2H6 to preserve hydrogen. Given this get the oxygen yourself, make sure you have the same thing on both sides and then convert to whole numbers.
If you can't do this then drop out of chemistry.
2C2H6 + 7O2 -> 6H2O + 4CO2
2C2H6 + 7O2 -> 6H2O + 4CO2
hope it helps
