The mass is 224 grams of NaOH
Answer:
HF - hydrogen bonding
CBr4 - Dispersion
NF3 - Dipole-dipole
Explanation:
Hydrogen bonding occurs when hydrogen is covalently bonded to a highly electronegative atom such as fluorine, chlorine nitrogen, oxygen etc. Hence the dominant intermolecular force in HF is hydrogen bonding.
CBr4 is nonpolar because the molecule is tetrahedral and the individual C-Br dipole moments cancel out leaving the molecule with a zero dipole moment hence the dominant intermolecular force are the dispersion forces.
NF3 has a resultant dipole moment hence the molecules are held together by dipole-dipole interaction.
Answer:
It seems to be that ROCKS are absolutely a "HARD SOLID", this is because many hard solids take SO LONG to decompose, but to answer your question, It takes so long because rocks a compressed solids...
Explanation:
This answer came straight from my brain... hope it was helpful!
**Remember to Mark your best answer! :-)
The answer is (4) Sc. The metallic properties has the rule that from left to right, the metallic property is from high to low. Then from the position of these four elements, we can get the answer.
