When components do not combine chemically, it is a _____. compound substance mixture molecule
2 answers:
Answer: Option (c) is the correct answer.
When an atom donates or shares its valence electrons with other atoms then it results in the formation of a new atom. This means a chemical has occurred as the chemical composition of products will be different from the reactants.
Whereas a substance is a matter which contains specific composition with some specific properties.
When two or more substance are mixed together then it is known as a mixture. It is not necessary that substances added will combine with each other.
When atoms of similar element chemically combine together then they result in the formation of a molecule.
For example,
Therefore, we can conclude that when components do not combine chemically, it is a mixture.

Answer:
Explanation:
From the given information, since the molecular mass of the ion M+ is not given;
Let's assume M+ = 58.0423
So, by applying the 13th rule;
we will need to divide the mass by 13, after dividing it;
The quotient n = no. of carbon; &
The addition of the quotient (n) with the remainder r = no. of hydrogen.
So;
So;
From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing . Also, since the mass is an even number then Nitrogen is 0.
So, we have:
Answer :
- The Noble gasses are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), Radon (Rn).
- When air is cold, Oxygen liquefies first at
.
liquefies at
. About 1% of the air is still gas composed of the noble gas Argon, Ar.
- One noble gas was discovered on the sun. It’s spectrum was identify first. This is Helium, He.
- One of noble gas is radioactive and seeps up your basement floors and walls. It is Radon, Rn.
- This noble gas is used in electronic flashes and other bright lights. It is Xenon, Xe.
- This noble gas is best known for its orange color in gas discharge tubes. It is used for signs that bear its name. It is Neon, Ne.
