Which is a reactive nonmetal???
ololo11 [35]
Sodium is very reactive but it’s a metal, and the problem asks specifically for a non-metal.
Silicone is technically reactive, but not super reactive.
Argon is a nonmetal, however it is an inert gas. It doesn’t react with anything.

We’re left with Chlorine, which is a non-metal in group 7, a highly reactive group, on the periodic table.

Tatiana [17]

Answer:

They are classified as METALS.

Explanation:

Elements are simple substances that cannot be chemically broken down into smaller substances. Based on different characteristics, they are classified into 3 namely:

- metals

- non metals and

- metalloid( mainly act as semi- conductor).

METALS are the type of elements that loses electrons to form positive ion, that is, they are electropositive elements. They are distinguished by the following characteristics:

- LUSTROUS: they have the ability to reflect light from its surface.

- At room temperature: Metals are solid are room temperature with the exception of Mercury which is liquid at room temperature.

- They react and form Basic Compounds

- Great conductor: most metals are great conductors of heat and electricity because they possess free electrons.

- Melting Point: they have high melting points.

Chemists use activity series to determine whether which type of reaction will occur?
ruslelena [56]
Single replacement reactions.  For example copper is more reactive than silver.  So a copper wire in a silver solution will cause the silver to become a metal again.

Where does o2 and CO2 gas exchange occur?
mixer [17]

The O₂ and the CO₂ gas exchange occurs in alveoli. the oxygen gas moves from the lungs and at same time carbon dioxide passe the the lungs from the blood and the gas exchange occurs.

The oxygen gas moves from the lungs and at same time carbon dioxide passe the the lungs from the blood and gas exchange between the alveoli and the tiny blood vessels occurs. the tiny blood vessels are called as the capillaries. the capillaries are located at the alveoli walls. every person has the hundred of millions of the alveoli present in their lungs.

Thus,  in the alveoli the exchange of the oxygen gas and the carbon dioxide gas will occurs.
