dusya [7]

Answer:

4.38g

Explanation:

70.0/2 = 35g - 20 mins

35/2 = 17.5g - 40 mins

17.5/2 = 8.75g - 60 mins

8.75/2 = 4.375g - 80 mins

In 1901, Thomas Edison invented the nickel-iron battery. The follwing reaction takes place in the battery.
lys-0071 [83]

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.
