Answer:
1) Pecan tree 1 and Pecan tree 4
2) I don't know
Explanation:
Answer:
hydrogen bonds are very weak and can only occur when polar covalent bonds are present
Explanation:
Hydrogen bonds are weak intermolecular interactions that occur when hydrogen is covalently bonded to a highly electronegative atom.
Owing to the difference in electro negativity between hydrogen and the highly electronegative atom, the bond is a polar covalent bond.
This hydrogen bond is a weak bond but accounts for properties such as high melting and boiling points of small molecules such as water and ammonia.
The answers are the following:
1. <span>1.4 x 10^11 kJ/mol
2. </span><span>9.0 × 10^6 kJ
Therefor I conclude that your answers are correct. </span>
"(2) static solution equilibrium" is the type of equilibrium that exists in a sealed flask containing Br2(ℓ) and Br2(g) at 298 K and 1.0 atm.
