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.

Lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
<h3>Young's modulus </h3>
From the question, we are to determine the statement which is true
First, we will define the term <em>Young's modulus </em>
<em>Young's modulus</em> is a measure of the stiffness of an elastic material. It is also given as the ratio of <u>stress </u>to <u>strain</u>. That is,
The greater the modulus, the stiffer the material.
Materials with low Young's modulus tend to be <u>ductile </u>and materials with high Young's modulus tend to be <u>brittle</u>
Since the Young's modulus value for iron is higher than that of lead, then iron is <em>stiffer </em>than lead.
Thus, lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
