Isotopes of atoms d. have the same number of protons but a different number of neutrons.
Answer ————
60.8 g ammonia
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:
true
Explanation:
Temperature is a measure of the average kinetic energy of the molecules, so energy would naturally be transferred from the molecules with more kinetic energy to the molecules with less kinetic energy
