Answer:
D) hydrogen bonds
Explanation:
Hydrogen bonds are <em>intermolecular forces</em> — they are the forces of attraction between two different molecules.
For example, the partially positive H atom in HF is strongly attracted (H-bonded) to the partially positive F atom in a different HF molecule:
H-F···H-F.
All the other items are <em>intramolecula</em>r — they occur within a single molecule.
A) Electronegativity. <em>Wrong</em>. Arises between the two atoms that are bonded together in a single molecule<em>.
</em>
B) Double bonds. <em>Wrong</em>. Occur between two adjacent bonds in a single molecule, e.g., propene, CH₃CH=CH₂.
C) Covalent bonds. <em>Wrong</em>. Occur in a single molecule, e.g., methane, CH₄.
Answer:
an
Explanation:
It is AN because investigation starts with I ( i is a vowel). When there are vowels we use An.
Pls mark me brainliest!
Answer:
Explanation:
Group Most Likely Ionic Charge Number of Valence Electrons
I +1 1
II +2 2
III +3 3
IV +4 or -4 4
V -3 5
VI -2 6
VII -1 7
VIII 0 8
For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)
Answer:
2 Moles
Explanation:
12 grams of carbon contains 1 mole
1 gram contains [1 mole/ 12 grams ] x 1 gram
24 grams contains [1 mole/ 12 grams ]* 24 gram = 2 moles.
Chemical property because heat is not electrical.
