<em>K</em>_eq = 0.14
The chemical equation is
A ⇌ B
The equilibrium constant expression is
<em>K</em>_eq = [B]/[A]
If [A] = 7[B]
<em>K</em>_eq = [B]/{7[B]}= 1/7 = 0.14
The answer is all elements are balanced.
The answer is (D) microscopic. You can remember this, because the name is very close to "microscope," an instrument used to greatly magnify and observe tiny organisms and objects.
Strong Acid has a lower pH level than a weak acid, weak acid pH level will be closer to 7 than the strong acid. Weak acid does not dissociate completely, therefore a weaker proton donor, thus higher pKa. Strong acids dissociates completely and release all of their hydrogen atom when dissolve in water.
