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.
Answer:
distance velocity displacement, all three
Explanation:
Mass number is the total number of Protons and Neutrons. Simply subtract 85 from 210. 210-85=125 neutrons
Elements that form diatomic molecules, or molecules of two atoms each, are commonly found on the right side of the periodic table.
