It involve both experimentation and repeated observations
Answer:
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:
- Tarnishing.
- Heat of combustion.
- Flammability.
- Acidity.
- Chemical reactivity.
Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.

Answer:
Sexual reproduction.
Explanation:
Like most mammals, giraffes produce sexually, meaning that both parents contribute to the DNA of the offspring.
Answer:
it's synthesis........
two different atoms/molecules form a different compound.
Molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
