Question

how balance a chemical equation i don't please tell me with the exmples

Answer 1

hello!!!

✌✌✌✌

here's your answer.......

some chemical reactions which provide us information about the reactants products but these reactions do not obey the law of conservation of mass it means in such reaction the mass of reactant is not equal to mass of product search reaction and unbalanced chemical reaction this reaction get balance by increasing the different coefficient of the reactant and product.

Answer 2

? CH4 + ? O2 → ? CO2 + ? H2O

Identify the elements in the equation: C, H, O

Identify the net charge: no net charge, which makes this one easy!

H is found in CH4 and H2O, so it's a good starting element.

You have 4 H in CH4 yet only 2 H in H2O, so you need to double the coefficient of H2O to balance H.1 CH4 + ? O2 → ? CO2 + 2 H2O

Looking at carbon, you can see that CH4 and CO2 must have the same coefficient.1 CH4 + ? O2 → 1 CO2 + 2 H2O

Finally, determine the O coefficient. You can see you need to double the O2 coefficient in order to get 4 O seen on the product side of the reaction.1 CH4 + 2 O2 → 1 CO2 + 2 H2O

Check your work. It's standard to drop a coefficient of 1, so the final balanced equation would be written:CH4 + 2 O2 → CO2 + 2 H2O
