Answer:
Explanation:
The molecular mass of C2H6 is approximately 30 or [(2 x 12) + (6 x 1)]. Therefore the molecule is about 2.5 times as heavy as the 12C atom or about the same mass as the NO atom with a molecular mass of 30 or (14+16).
Explanation:
Carbon dioxide isn't a polar molecule because
same nature of charge appears in opposite direction which cancel each other. So, carbon dioxide is non-polar molecule.
Answer: The number of atoms remain constant and thus the mass also remains conserved.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
In product side , there are 2 atoms of potassium, 2 atoms of nitrogen and 6 oxygen atoms. In there is 1 atom of lead and 2 atoms of iodine.
In reactant side , there are 2 atoms of nitrogen, 6 oxygen atoms and 1 atom of lead. In there are 2 atoms of potassium and 2 atoms of iodine.
Thus the number of atoms remain constant and thus the mass also remains conserved.
