Answer:
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
Explanation:
Explanation :
The balanced chemical reaction will be,
By the stiochiometry, 3 moles of solid copper(II)oxide react with 2 moles of ammonia gas to give 3 moles of copper metal, 1 mole of nitrogen gas and 3 moles of liquid water.
The states of matter of each elements and compound is,
Copper(II)oxide is in solid state
Ammonia is in gaseous state
Copper metal is in solid state
Nitrogen is in gaseous state
Water is in liquid state
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.
