Which of the following statements are wrong?
1.6 g of a hydrocarbon on combustion in excess of oxygen produces 1.2 of CO2 and 0.4 of H2O. The data illustrates the law of conservation of mass.
The product of atomic mass and specific heat of any elements is a constant and is approximately 6.4. This is known as Dulong Petit's law.
The atomic masses of the elements are usually fractional because they are mixtures of allotropes.
The best standard of atomic mass is hydrogen -1.008.
(1) total mass of products is 1.6 grams ,where as in reactants only hydrocarbon alone is 1.6 grams, we have to also consider the weight of oxygen
