All of the other options are ways that could help the environment from the chemicals, but if they just continue to use the chemicals then it would hurt the environment
Answer:
carbon-12 is not radioactive
Explanation:
The measurement of the age of dead carbon based life forms requires the use of a radioactive isotope hence it is often referred to as radiocarbon dating.
Carbon-12 and Carbon-14 occur together in living things.The half life of Carbon-14 is about 5670 years.
Hence, since Carbon-12 is not radioactive, it can not be used to measure the age of dead carbon based materials.
Answer:
Balanced Eqn
2C2H6 + 7O2 = 4CO2 + 6H2O
From the balanced equation
2((2*12)+(1*6)) of Ethane gave 6((1*2)+16)) of water
60g of Ethane. >. 108g. Of water
Xg > 1.61
X= 1.61*60/108
X= 0.89g
