Answer:
Ionic compound.
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element. the electrostatic attraction is created between bonded atoms.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion and both atoms joint together through electrostatic interaction.
<h3>Answer:</h3>
36.70 amu
<h3>Solution:</h3>
Data Given:
Atomic Mass of ³⁵Cl = 34.9700 amu
Natural Abundance of ³⁵Cl = 13.85 %
Atomic Mass of ³⁷Cl = 36.9700 amu
Natural Abundance of ³⁷Cl = 86.15 %
Formula Used:
Average Atomic Mass = [(Atomic Mass of ³⁵Cl × Natural Abundance of ³⁵Cl) + (Atomic Mass of ³⁷Cl × Natural Abundance of ³⁷Cl)] ÷ 100
Putting values,
Average Atomic Mass = [(34.9700 × 13.85) + (36.9700 × 86.15)] ÷ 100
Average Atomic Mass = [(484.3345) + (3184.9655)] ÷ 100
Average Atomic Mass = 3669.3 ÷ 100
Average Atomic Mass = 36.70 amu

The gas is NH₃.
H₂ doesn't dissolve readily in water, SO₂ gives an acidic solution in water.
The solid residue is Fe(OH)₂.
FeSO₄ and Na₂SO₄ are soluble in water.
The answer is C.
