<h2>DIFFERENCE BETWEEN CRYSTALLINE AND AMORPHOUS SOLIDS :</h2><h2><em><u> Amorphous solids do not have definite melting points but melt over a wide range of temperature because of the irregular shape. Crystalline solids, on the other hand, have a sharp melting point.</u></em></h2>
1 is element 2 is element 3 is compound 4 is element 5 is nothing in and water is a compound
Answer:
The obtained result indicates that the hydrogen atom is not equal on both sides. Thus the reaction is not balanced.
Explanation:
Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
<h3>What is Empirical Formula ? </h3>
The Empirical formula is the simplest whole number ratio of atoms present in given compound.
<h3>What is Molecular formula of Compound ?</h3>
Molecular Formula = Empirical Formula × n
n = 
Thus from the above conclusion we can say that Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
