Answer:
wavelength = 2.81 m
Explanation:
Given that,
The frequency of the Sports Fan radio station, f = 106.4 MHz
We need to find the wavelength (in meters) of the electromagnetic carrier wave. The relation between frequency and wavelength is given by :
Where,
is wavelength
So, the wavelength of the electromagnetic carrier wave is 2.81 m.
1.7960L
Explanation:
the mass of the gas is constant in both instances
pv/T=constant(according to pv=nRT)
745mmHg*2L/298K=760mmHg*v/273K
v=1.7960L
Answer:pKa between 6 and 8
b. highly water soluble
c. minimally permeable to biological membranes
d. minimal effects of salt concentration
Explanation:
Since most biological reactions occur at near neutral pH of 6-8, good buffers should have their pKa around this region. A good buffer must also be water soluble and not easily permeable to biological membranes to avoid to avoid accumulation of the buffer compound in cells. The buffer should also not be highly ionic to prevent issues due to salt effects.
