Answer: The empirical formula for the given compound is 
Explanation : Given,
Percentage of H = 18 %
Percentage of N = 82 %
Let the mass of compound be 100 g. So, percentages given are taken as mass.
Mass of H = 18 g
Mass of N = 82 g
To formulate the empirical formula, we need to follow some steps:
Step 1: Converting the given masses into moles.
Moles of Hydrogen = 
Moles of Nitrogen = 
Step 2: Calculating the mole ratio of the given elements.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 5.8 moles.
For Hydrogen = 
For Nitrogen = 
Step 3: Taking the mole ratio as their subscripts.
The ratio of H : N = 3 : 1
Hence, the empirical formula for the given compound is 
Answer:
Actually there is no answer but there is so much theories but people mostly says Bug Bang
Answer:
Fe.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> Fe goes from + 2 to +3, so, it is the element that is oxidized.</em>

Answer:
It does not always retain the properties of the substances that make it up
It requires heat energy to make
Explanation:
A compound is a chemical substance composed of two or more kinds of atoms or elements joined together in a definite grouping.
The properties of compounds are distinct from those of individual elements that are combined in its make up.
- To produce a compound, a chemical change must take place
- As with most chemical changes, heat is required to drive the change.
- So, to form compounds, some amount of heat is needed to cause the change.
