Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.
I hope this helped :) If not i'm sorry!

Reactivity series
is an empirical progression of a series of metals, arranged by their reactivity
from highest to lowest (alkaline metals have highest reactivity and Noble
metals lowest reactivity).
This series are used to summarize information about
the reactions of metals with acids or water, double displacement reactions
(more reactive metals displace metals with lower reactivity) and the extraction
of metals from their ores.
In this example, barium is more reactive than magnesium, iron, chromium and zinc are less reactive.
V, Vanadium is the metallic element
Below is the drawing of structural formula of alkenes that undergo acid-catalyzed hydration without rearrangement
