That would be B which is bathypelagic zone because at the top there is light and the deeper you get the darker it is
Answer:
- <u><em>Last choice: 109.729 g</em></u>
Explanation:
This is a combustion reaction. The complete combustion of a hydrocarbon produces carbon dioxide and water.
The combustion reaction of<em> isopropyl alcohol</em> is represented by the balanced hemical equation:
Thus, 2 moles of produce 8 moles of .
<u>1. Convert the 91.5 g of isopropyl alcohol into number of moles</u>
- Number of moles = molar mass / fomula mass
- Number of moles = 91.5g / (60.95592g/mol) = 1.52256692 mol
<u>2. Calculate the the number of moles of water produced using the mole ratio:</u>
<u />
<u>3. Convert to mass of water</u>
- Mass = number of moles × molar mass
- Molar mass = 2 × 1.00794 g/mol + 15.9994g/mol = 18.01528g/mol
- Mass = 6.0902637 mol × 18.01528 g/mol = 109.717806g ≈ 109.72 g
So far, I have kept a large number of digits because these are intermediate calculations.
You should report the result with 3 significant figures, but all the answer choices contain more than that.
The last choice, 109.729, is the closest to the correct value.
Answer:
Poor Science
Explanation:
I took the quiz also just think that doesn't seem like a good, higher level scientist, or popular one, SO THERE YOU GUYS GO!!!
Answer:
Manganese (II) Phosphate
Explanation:
Mn3(PO4)2 is the compound given in this question. Manganese is the metal and hence it will come first in the name. Along with the name of metal it is essential to determine the valency of the metals based on the compound structure.
Here 2 PO4 attaches with 3 Mn
Valence of PO4 is -3
So the total electrons contributed by PO4 is 3*2 = 6
Now Mn has 3 atoms in the compound. Thus, per atom the valency must be 2 in order to satisfy -6 charge of PO4
Thus, valency of Mn is 2
So, the name will be
Manganese (II) Phosphate.
