Definition of volcanos is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust , the definition of tornados is a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system and the definition of earthquakes is a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action
Answer:
Writing Formulas of Ionic Compounds
The cation is written first, followed by the monatomic or polyatomic anion. The subscripts in the formula must produce an electrically neutral formula unit.
Explanation:
NH₄F+ AICI₃, → NH₄CI + AlF₃
NH,F: in ionic form
NH₄⁺ + F⁻ = NH₄F
AICI in ionic form:
Al³⁺ + Cl⁻ = AlCl₃
NH Cl in ionic form:
NH₄⁺ + Cl⁻ = NH₄Cl
Al F in ionic form:
Al³⁺ + F⁻ = AlF₃
NH₄F+ AICI₃, → NH₄CI + AlF₃
Now we have to balance the equation with respect to the atoms:
aNH₄F+ bAICI₃, → cNH₄CI + dAlF₃
for N: a = c
H: 4a = 4c
F: a = 3d
Cl: 3b = c
let a = 1
c = 1
b = 
d =
Therefore we can imply that:
a = 3, b = 1 , c = 3 and d = 1 if we multiply through by 3
3NH₄F+ AICI₃, → 3NH₄CI + AlF₃
