Answer:
Empirical formula is K₃PO₄.
Explanation:
Given data:
Percentage of K = 55%
Percentage of P = 15%
Percentage of O = 30%
Empirical formula = ?
Solution:
Number of gram atoms of K = 55 / 39.098 = 1.41
Number of gram atoms of P = 15 /30.974= 0.48
Number of gram atoms of O = 30 / 15.999 = 1.88
Atomic ratio:
K : P : O
1.41/0.48 : 0.48/0.48 : 1.88/0.48
3 : 1 : 4
K : P : O = 3 : 1 : 4
Empirical formula is K₃PO₄.
Hey there !:
HF s molecule with the strongest intermolecular force
<span>HF > HI > HBr > HCl</span><span>
</span>The main factor of influence at the boiling point is the question of intermolecular forces, but not only that, the molar mass also has influence (the greater the molar mass, the greater the boiling point). Note that the only one forming hydrogen bridges is the HF, therefore the largest boiling point, iodine, bromine and chlorine have the same type of intermolecular (permanent dipole) connections as they are polar, and what will differentiate the boiling point of each one is the molar mass.

Her adverage speed would be 160 meters per second!
If you feel the answer is incorrect please comment and I will revise! Have a good day!
Proof:
2 minutes=250 meters
6 minutes=1,250 meters
7 minutes=1,600 meters
10 minutes= 1,600 meters
Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!
The answer to your question is
D) Blowing sand can wear away a rock's surface and break it into smaller pieces
When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.
Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.
I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.
Please give me brainliest if I was correct and helpful!
Otherwise, please comment and let me know how I can fix my answer!
Thank you, it was fun, have a nice week!
