Answer:

The type of evidence that is more difficult to collect is evidence known as trace, for example, fibers, hair, or signs of dirt.

Explanation:

For the collection of this type of evidence, specialized equipment such as special vacuum cleaners, tweezers, etc. are used, all with the purpose of carrying out the collection of trace evidence. This type of evidence is characterized by being very difficult to find.

Write the general chemical formula for an acid, and discuss what each component of the formula represents.
saul85 [17]
The general formula of an acid is HX where H+ acts as the cation while X can be a halogen (Cl-, Fl-, Br-, etc) and acts as the anion. There are also cases where X is an ion like SO42-, which brings two atoms of H in the formula. Strong acids dissociate completely while weak acids do not.
