20 mol of NH, can be produce from 30 mol o H2
B. the periodic law
Explanation:
The periodic law was not explained by the Dalton's atomic theory.
The periodic law was first postulated by Dimitry Mendeleef and Lothar Meyer around 1869 where they independently arrived at the periodic table or chart.
- The table was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- The modern periodic law was restated by Henry Moseley in the early 1900s. He changed the basis of the law to atomic number.
- The present periodic law is stated as "the properties of elements are a periodic function of their atomic number".
The laws of conservation of mass, multiple proportions and definite proportions are all explained by the Dalton's atomic theory.

The binding energy of electrons in a metal is 193 kJ mol ^-1 .
<h3>What is binding energy?</h3>
The minimal amount of energy needed in physics and chemistry to separate a particle from a system of particles or to break a system of particles down into its component pieces is known as the binding energy. While the word separation energy is used in nuclear physics, the former meaning is more common in condensed matter physics, atomic physics, and chemistry.
The energy level of a bound system is often lower than that of its unbound components. Relativity theory states that a drop in a system's total energy of E leads to a corresponding decrease in its total mass of m, where
Δmc² = E.
