The answer is low frequency and long wavelength
Answer:
oh coooool
I have one Id it is on ace with maybe 5800 points
maybe this picture will help in something
For the purpose we will here use the ideal gas law:
p×V=n×R×T
V= ?
n = 0.5 moleT= 273.15 K (at STP)
p= 101.325 kPa (at STP)
R is universal gas constant, and its value is 8.314 J/mol×K
Now when we have all necessary date we can calculate the number of moles:
V=nxRxT/p
V=0.5x8.314x273.15/101.325= 11.2 L = 11200 mL
Answer: D.
Those are types of water on a pH scale 7.0 and above are alkili water and anything under that is acidic
