<span>An ionic crystal consists of ions bound together by electrostatic attraction. The arrangement of ions in a regular, geometric structure is called a crystal lattice. Examples of such crystals are the alkali halides, which include: potassium fluoride (KF)</span>
<u><em>Answer</em></u>
= 3.405 × 10⁻⁴
<u>Explanation</u>
If the question is correctly written, then it is very easy.
First, take the like terms on one side.
493x = 3432x+1
493x - 3432x = 1
-2939x = 1
Dividing both sides by -2939 to get the value of x.
x = 1/(-2939)
= - 0.0003405
= 3.405 × 10⁻⁴
