<h3>What is
Fluorine?</h3>
The chemical element fluorine has an atomic number of 9 and the symbol F. The lightest halogen, it is an extremely poisonous, pale yellow diatomic gas under normal conditions. It is exceedingly reactive and, as the most electronegative element, reacts with all other elements with the exception of argon, neon, and helium.
Fluorine is the 24th most abundant element overall and the 13th most abundant on Earth. In order to decrease the melting temperatures of metal ores for smelting, fluorite, the main mineral source of fluorine, was added. The Latin verb fluo, which means "flow," gave the mineral its name. Fluorite was first described in 1529.

Answer:
d
Explanation:
the reason is you have Cu S and O
First you must write a balanced chemical equation.
C3H8 + 5O2 --> 3CO2 + 4H2O
From there, we can set up the stoichiometry equation to solve.
g O2= 70.2 g C3H8 X (1 mol C3H8/44.0962g C3H8) X (5 mol O2/1 mol C3H8) X (31.998g O2/1 mol O2)
Now solve, and you should get 254.7 g O2. Hope this helped!
Answer:
The P Wave travels through Earth's crust more quickly than the S wave travels
Explanation:
P and S waves are types of seismic waves that travel through Earth's crust.
Some basic data we can read from this graph are:
- it takes around 13 minutes for P wave to travel 10000 kilometers.
- it takes around 25 minutes for S wave to travel 10000 kilometers.
Based on this data, we can conclude that, since P wave takes less time then S wave to travel the same distance, that means that it moves through Earth's interior more quickly.
