Answer:
hi! merry xmas!
Explanation:
Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.
Answer:
0.384g/l
Explanation: the density version of the ideal gas law is pm=drt
in which p= pressure, m=molar mass,d=, density, r= to a constant which is 0.08206, and t=temperature so just input the values
PM=DRT. so to find d the formula would be D=RT\PM
D=<u>0.08206*242.5</u>
0.7311*70.90
D=0.384g/l
A)2nd period - Li, Be, B,C,N,O,F,Ne
b)Metalls of the 2nd period are Li,Be
Answer:
P= 138.6 atm or 1.4x10²
Explanation:
You will need to use PV=nRT to solve for P, pressure
Where the R constant is 0.08206 L atm mol^-1 K^-1
V is 1.2 L
T is temperature in kelvin, 273.15+25= 298.15
n is 6.8 mol
P*1.2=6.8*0.08206*298.15 ---> P*1.2=166.3700852 ---> P=166.3700852/1.2
P=138.6 atm
or 1.4x10²
