<h3>Answer:</h3>
Ionic Bond
<h3>Explanation:</h3>
Types of Bonds can be predicted by calculating the difference in electronegativity.
If, Electronegativity difference is,
Less than 0.4 then it is Non Polar Covalent Bonding
Between 0.4 and 1.7 then it is Polar Covalent Bonding
Greater than 1.7 then it is Ionic Bonding
For Mg and Cl,
E.N of Chlorine = 3.16
E.N of Magnesium = 1.31
________
E.N Difference 1.85 (Ionic Bond)
<h3>Conclusion:</h3>
MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.
Answer:
a scientific question
Procedure
Conclusion.
Explanation:
Scientific investigation is usually carried out to explain and give answers to natural phenomenon. Now, this scientific investigation is performed through the three main types as described in the question.
With that being said, the most common parts of all types of investigation are :
1. Scientific question: In this stage, questions are usually asked on the basis of observation made which could be answered.
2. Procedure: In this stage, the dimension of the steps are followed to answer and test the scientific question.
3. Conclusion: This is the primary aim that we check when done with our sample values

Answer:
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
Explanation:
Empirical formula:
It is the simplest formula that gives the smallest whole number ratio between the atoms of elements present in a compound.
Given data:
Mass of iron = 87.47 g
Mass of oxygen = 12.53 g
Empirical formula = ?
Solution:
Number of gram atoms of iron = 87.47 /55.845 =1.57 grams atoms
Number of gram atoms of oxygen = 12.53 / 16 = 0.78 grams atoms
Atomic ratio:
Fe : O
1.57/0.78 : 0.78/0.78
2 : 1
Fe : O = 2 : 1
Empirical formula:
Fe₂O
Subscript of iron in empirical formula is 2.
In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
