<span>Johannes Kepler, an apprentice of Brahe, believed in the heliocentric universe but rejected past astronomers' belief in "Circular Orbit Path." The circular orbit path refers to the path the planets in the solar system is following. It is believed before that it follows a circular path rather than an elliptical one.</span>
Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
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.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products
, Thus results are in accordance with the law of conservation of mass.
