Answer:
Below!
Explanation:
Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.

If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.
<h3>What is molarity?</h3>
Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of moles of solute per liter of solution.
We want to find the moles of iron (II) nitrite (solute) in 125 mL of a 3.5 M solution. We will use the definition of molarity.
M = n / V(L)
n = M × V(L) = 3.5 mol/L × 0.125 L = 0.438 mol
where,
- M is the molarity.
- n is the number of moles.
- V(L) is the volume of the solution in liters.
If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

Answer:
As the use of plants as carbon sinks can be undone by events such as wildfires, the long-term reliability of these approaches has been questioned. Carbon dioxide that has been removed from the atmosphere can also be stored in the Earth's crust by injecting it into the subsurface, or in the form of insoluble carbonate salts (mineral sequestration).
