Answer:
The answer to your question is: hydrogen bonding
Explanation:
Hydrogen bonding is a kind of interaction dipole-dipole, that means that 2 molecules attract each other because the have partial charges.
In the picture we can see 4 molecules of water, red circles are oxygens and white circles are hydrogens. In this bonding, Oxygen due to its size, and atomic number is more electronegative than hydrogen, then in water molecule is formed a partial negative charge in oxygen and a partial positive charge in hydrogen.
Finally, because of this partial charge, one oxygen can bond to one hydrogen of another molecule.
Answer:
9.308
Explanation:
The computation of the pH of the given solution is shown below:
But before we need to determine the HI molarity which is
= 0.1852 M
Now
As we know that
So,
Now the molarity of 
left is
= 0.397 - 0.1852
= 0.2118
= 4.692
Now as we know that
pH = 14 - pOH
= 14 - pOH
= 14 - 4.692
= 9.308
We simply applied the above equations
Answer:
8.7 mol Al
Explanation:
You have the compound Al₂Si₄O₁₀(OH)₂. Within the compound, you have atoms. You can tell how many atoms there are by looking at the subscript. You have 2 aluminum atoms, giving you 8.7 moles of aluminum.
4.35 × 2 = 8.7
Answer C
I could be wrong
Explanation
Answer:
Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.Jul
