Answer: The number of moles of Fe(OH)_2  produced are, 3.60 moles.

Explanation :

First we have to calculate the limiting and excess reagent.

The balanced chemical equation is:

Fe(s)+2NiO(OH)(s)+2H_2O(l)\rightarrow Fe(OH)_2(s)+2Ni(OH)_2(aq)

From the balanced reaction we conclude that

As, 1 mole of Fe react with 2 mole of NiO(OH)

So, 3.60 moles of Fe react with 3.60\times 2=7.2 moles of NiO(OH)

From this we conclude that, NiO(OH) is an excess reagent because the given moles are greater than the required moles and Fe is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of Fe(OH)_2

From the reaction, we conclude that

As, 1  mole of Fe react to give 1 mole of Fe(OH)_2

So, 3.60 mole of Fe react to give 3.60 mole of Fe(OH)_2

Therefore, the number of moles of Fe(OH)_2  produced are, 3.60 moles.

Which is a substance that could be found in air, water, or soil that is harmful to humans or animals? carbon dioxide fossil fuel
quester [9]
Hi!

The substance that could be found in air, water or soil that is harmful to humans or animals is called pollutant.

Pollutants are the only harmful substances that can be found in these three places. Carbon Dioxide (CO₂) is commonly found in the air, fossil fuels are found in soil and water and smog is found in the air. Only pollutant can be found in these three places as there are varied in its chemical structure. Common pollutants include Sulfur Dioxide (SO₂) which can be found in the air, and Lead, which can be found in water or soil.
