They could have similar environments which require them to adapt similar characteristics
for example the dolphin and shark are not related but due to their aquatic environment they have similarly shaped tails and fins
the process or species getting more similar over time is called called convergent evolution
Total mass of CaCO3 = 40 amu of Ca + 12amu of C + 16×3 amu of oxygen = 100amu of CaCO3
i.e 100 tonnes of CaCO3 .
mass of CO2 = 12amu of C + 2× 16amu of O = 44 amu of CO2
mass % of CO2 in CaCO3 = (44/100)×100 =44%
i.e
44% of 100 tonnes is CO2.
=44 tonnes of CO2.
therefore, 44% of CO2 is present in CaCO3.
We know, change in temperature is given by :
Putting all given values, we get :
Hence, this is the required solution.
Don’t understand lol... but I’m chasing those points so thanks
Combustion. You said CH4 'burns' in the question which is another word for combustion.
