Oxygen is balanced incorrectly.
The correct balanced equation: 2C6H6+15O2=12CO2+6H2O
Answer:
you can simply answer vl\t1=v2/t2
2H2 + O2 = 2H2O since two elements created a compound, in this case water.
Answer:
No, these sample could no be same
Explanation:
Percentage of copper in both sample are different means both are taken from different sample because if we says both are from same sample then its violates the law of definite proportion
according to this law a given compound always contains same proportion of element by mass and it does not depend on the source
eg: water from sea and drainage both have same composition means same amount of oxygen and hydrogen by mass is present
Hence given samples are not same
