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.

The chief advantage of the metric system over other system of measurement is that it
kolbaska11 [484]

Answer:

The metric system goes by powers of ten, so it's very easy to measure. That would be the main advantage, measurements of ten. We can also say it's the most used measurement around the world, so all scientists have little to no conversion, but the main answer is probably the first one :)

7. How many moles are in 18.00 x 1023 particles of AICIZ?
Andrej [43]

Answer:

<h3>The answer is option A</h3>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}  \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{18.0 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{18}{6.02}  \\  = 2.99003322...

We have the final answer as

<h3>2.99 moles</h3>

Hope this helps you
