Answer:
Explanation:
1. The smallest complete unit of a compound or diatomic gas
ATOM
Atoms are small tiny particles that makes up a molecule. It is regarded as the smallest indivisible particle that parts in a chemical reaction.
2. A new substance formed by the combination of two or more different atoms
COMPOUNDS
Compounds are substances composed of two or more kinds of atoms. Their properties differs from those of the constituent elements that combines to make them up.
3. Path of electrons around an atomic nucleus
SHELL
The shell describes the path of an electron round a nucleus
4. A substance consisting of only one type of atom
MONOATOMIC MOLECULE
It is an aggregate of one type of atom.
Answer:
It depends on what kine of unknown substance you're referring to.
Explanation:
What do you mean by unknown substance?
If it's soluble in water and can conduct electricity then it is an ionic compound.. If it is insoluble in water and can't conduct electricity then it is a covalent compound
Answer:
CO.
Explanation:
Assuming the given percentages are by mass, we can solve this problem via imagining we have <em>100 g of the compound</em>, if that were the case we would have:
Now we <u>convert those masses into moles</u>, using the<em> elements' respective molar masses</em>:
- 42.9 g of C ÷ 12 g/mol = 3.57 mol C
- 57.1 g of O ÷ 16 g/mol = 3.58 mol O
As the number of C moles and O moles is roughly the same, the empirical formula for the compound is <em>CO</em>.
Answer:
I believe the answer is all amoeba come from other amoeba
A noble gas is different from other elements because <u>they are the most stable elements that can have the maximum number of valence electrons on their outer shells.</u> This characteristic allows the noble gases to rarely react with other elements, unlike all the other elements found within the periodic table. Nobel gases are found in the group 18 of the periodic table and these are Argon, Neon, Krypton, Xenon, Organesson, Helium, and Radon.
