Answer:
Vanderwaals forces
Explanation:
CBr4 is a nonpolar molecule, nonpolar molecules usually possess vanderwaals forces between their molecules as their main attractive force.
CBr4 is nonpolar because the tetrahedral arrangement of the C-Br bonds cancel out the individual dipole moments of each C-Br bond thereby making the compound nonpolar, hence the answer above.
Answer: He is modeling the condensation process in the water cycle.
Answer:
d. p3-
Explanation:
Phosphorus has fifteen electrons in its orbitals and five electrons in its outermost shell. An atom is said to have noble gas configuration when it has eight electron in its outermost shell.
In order to have eight electrons in its outermost shell, phosphorus must accept three electrons and form an ion of the sort P^3-. This ion now has eighteen electrons (argon configuration) and eight electrons in the outermost shell.
Answer:
31 moles
Explanation:
The balanced combustion reaction of the wax, 
is shown below as:
As seen from the reaction,
1 mole of wax, on combustion produces 31 moles of carbon dioxide, 
<u>Hence, moles of when 1 mole of wax, is burnt = 31 moles</u>
I thinks it's C although I'm not 100% positive.
