Answer:
NOAA and FWS are required by law to compare background rates to current rates.
Explanation:
Answer: Option (3) is the correct answer.
Explanation:
When there is a negative charge on an atom then we add the charge with the number of electrons. Whereas when there is a positive charge on an atom then we subtract the charge from the number of electrons.
Atomic number of chlorine is 17. So, number of electrons present in
is 17 + 1 = 18 electrons.
Atomic number of cobalt is 27. So, number of electrons present in
is 27 - 4 = 23 electrons.
Atomic number of iron is 26. So, number of electrons present in
is 26 - 2 = 24 electrons.
Atomic number of vanadium is 23. So, number of electrons present in V is 23 electrons.
Atomic number of scandium is 21. So, number of electrons present in
is 21 + 2 = 23 electrons.
Thus, we can conclude that out of the given species,
has the greatest number of electrons.
The answer is: B) Spills in your shop and any releases on pavement or outside should be poured down a drain.
Pouring used oil down a drain can cause damege to environment.
Oil is nonpolar substance and does not dissolve in the water (polar molecule), used oil remain existent in the drain and sewer or in the environment.
Small spills create a cumulative effect with significant impact on the environment.
Untended spills inside a shop can spread to an inside drain connected to the storm sewer system and cause floods.
