It expands in the cracks (which I think is erosion) and it breaks the pavement because of the constant expansion and moving of pavement pushes it to break.
Answer:
b. H3O c. H2SO4 d. HNO3
Explanation:
The hydrogen bonds can be form with molecules that have free electron pairs and hydrogen atoms. In the case of NH4 molecule, the "free" electron pair in the nitrogen is not free because there is an hydrogen occuping them, and, in fact, this molecule has a positive charge. The other acids have free electron pairs in the oxigen, nitrogen or sulfur.
We will use Ideal gas equation.
PV=nRT
where
P= pressure(in atm)=5.82atm
V=Volume=?
n= moles of gases=0.682
R = gas constant= 0.0821L atm / mol K
T = temperature= 68.2 C= 68.2 + 273.15 = 341.35 K
V= nRT/ P= 0.682 X 0.0821 X 341.35/ 5.82
V= 3.284 L.
