Because they don't care and think the ozone layer is fine.
I couldn't really find anything about the growth time but it does say that it could remain viable in soil for up to 40 years
Varuable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation :)
The answer would be Force
Answer:
1.16atm
Explanation:
We are going to derive the mass of ether from density
mass=density *volume
Also moles=mass/molecular mass
molar mass C2H5OC2H5 =74.12 g/mole
the density of ether is 0.7134 g/ml
mass C2H5OC2H5 = 5.30 ml x 0.7134 g/ml = 3.78 g
moles C2H5OC2H5 =3.78 g x 1 mole/74.12 g = 0.0509 moles
PV = nRT where P=?; n=0.0509 moles; V=6.50L; R=0.0821 Latm/Kmol; T=35ºC +273 = 308K
P = nRT/V = 0.0509)(0.0821)(308)/6.50
P = 0.198 atm (to 3 significant figures (this is the partial pressure of diethyl ether).
TOTAL PRESSURE
P1+p2+p3
= 0.198 atm + 0.750 atm + 0.207 atm =1.1550atm
1.16atm(3 significant figures)
