Answer:
electron capture detectors (ECD)
Explanation:
Electron capture detectors (ECD) would be most sensitive for GC analysis of PCBs.
I hope my photo helps. since oxygen goes from a charge of 0 to -2, it gains electrons because electrons have a negative charge. nitrogen goes from 0 to +2 meaning that it is losing electrons to make it a positive charge.
Answer:
Calcium is the 20th element, with 20 protons. Since a stable atom has a net charge of 0, we must have 20 electrons. The number of neutrons will be the same as the number of protons, or else we will have an isotope, in this case, it is also 20.
Explanation:
<u>Given:</u>
Velocity of the dog, v = 5.4 m/s
Centripetal acceleration, a = 48.6 m/s2
<u>To determine:</u>
Radius of the path
<u>Explanation:</u>
The centripetal acceleration is related to the velocity and radius as:
a = v²/r
r = v²/a = (5.4 m/s)²/48.6 m/s2 = 0.6 m
Ans: Radius of the path is 0.6 m
