Answer:
limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
2H2 + 1 O2 ---> 2 H2O
from reaction 2 mol 1 mol
given 3.5 mol 2.5 mol
needed 3.5 mol 1.75 mol
Excess reactant O2, Limiting reactant H2.
Limiting reactant will be used completely.
So, limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
(a) CH₄
The molecule of methane is non polar in nature , hence it will show only the dispersion forces .
(b) NO₂
The molecule of nitrogen dioxide will show both dipole-dipole interactions and dispersion forces as well .
Since , the molecule is has an electronegative atom , i.e. , oxygen , so will show dipole - dipole interactions .
(c) SO₂
The molecule of sulfur dioxide will show both dipole-dipole interactions and dispersion forces as well .
Since , the molecule is has an electronegative atom , i.e. , oxygen , so will show dipole - dipole interactions .
Jupiter------------------------
D; They have partial charges and are bound together by dipole-dipole intermolecular forces.
