The answer is very probable because of how incredibly small atoms are
Very probable because of how incredibly small atoms are the chances that at least one of the atoms exhaled in your first breath will be in your last breath.
Hydrogen and oxygen always react in a 1:8 ratio by mass to form water. early investigators thought this meant that oxygen was 8 times more massive than hydrogen.
If you say that something is probable, you mean that it is likely to be true or likely to happen.
Everything around us is made up of really tiny molecules. However, such molecules are constructed from much smaller atoms. Then, even smaller protons, neutrons, and electrons are used to build those atoms. Quarks, which are even smaller particles than protons, make up protons.
The smallest unit of substance that may be disassembled without ejecting any electrically charged particles is the atom. The smallest piece of substance that displays an element's distinctive qualities is an atom. As a result, the atom serves as the basic unit of chemistry.

Answer:
12.7 mol
Explanation:
<em>A chemist measures the amount of fluorine gas produced during an experiment. He finds that 482. g of fluorine gas is produced. Calculate the number of moles of fluorine gas produced.</em>
Step 1: Given data
Mass of fluorine (m): 482. g
Step 2: Determine the molar mass (M) of fluorine
Fluorine is a diatomic molecule of chemical formula F₂. Its molar mass is:
mF₂ = 2 × mF = 2 × 19.00 g/mol = 38.00 g/mol
Step 3: Determine the number of moles (n) corresponding to 482. g of fluorine
We will use the following expression,.
n = m/M
n = 482. g/(38.00 g/mol)
n = 12.7 mol
Row 6 - it’s called Rare earth elements
found in lanthanide series.
Hope this Help
Answer:
1) Dissolve the crude substance in a minimum amount of hot solvent.
2) Filter the hot solution to remove the solid impurities (if present)
3) Allow the solution to cool slowly so crystals form.
4) Filter the crystals.
5) Dry the crystals
6) Weigh the crystals into a tared flask.
Explanation:
Recrystallization is a method used in chemistry to obtain crystals having a high degree of purity for the purpose of analytical or synthetic laboratory work.
