Question

when the following eqaution is balanced correctly the total sum of all coefficients will be:

when balanced the sum of coefficient for CuS will be:

Cu(NO3)2 + Na2S--> CuS + NaNO3

When the following equation is balanced correctly what is the coefficient for CO2 is:

C4 H10 + O2 --> CO2 + H2O

When the following equation is balanced correctly the coefficient for Al is:

Additionally, when the equation is balanced correctly the total number of O atoms on each side of the equation will be:

Al + O2 --> Al2O3

Explanation / Answer

balanced equation is:

Cu(NO3)2 + Na2S--> CuS + 2NaNO3

sum of coefficient=1+1+1+2=5
