It quadruples as they are directly proportional
Answer:
506.912 L
Explanation:
From the question given above, the following data were obtained:
Number of mole of O₂ = 22.63 moles
Volume of O₂ =?
Recall:
1 mole of a gas occupy 22.4 L at STP.
With the above information, we obtained the volume occupied by 22.63 moles of O₂ as follow:
1 mole of O₂ occupied 22.4 L at STP.
Therefore, 22.63 moles of O₂ will occupy = 22.63 × 22.4 = 506.912 L at STP.
Thus, 22.63 moles of O₂ is equivalent to 506.912 L.
Number of protons give atomic number, so Atomic number is 9.
Atomic mass =number of protons +number of neutrons=9+10=19
If we add 1 proton, then atomic number is going to be 10, and it would be Neon,
because number protons define atomic number and so type of element.
If we add neutron, atomic number is not going to change, so it still would be Fluorine, but isotope of Fluorine with different atomic mass that would be equal 20.
In order to obtain a sample of salt, you should heat the water until it boils and evaporates. The salt won't evaporate and will remain even after all the water is gone.
<span>4 Fe(s) + 3 O2(g) = 2 Fe2O3(s)
That is what it would be balanced, hope this helped</span>
