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.

Which of these electron transitions correspond to absorption of energy and which to emission?
Elan Coil [88]

Answer:

n = 5 to n = 6 absorption

n = 9 to n = 6 emission

n = 6 to n = 4 emission

n = 6 to n = 7 absorption

Explanation:

According to the Bohr's model of the atom. An electron in an atom may absorb energy and move from a lower energy level to a higher energy level. This requires absorption of energy that is equal to the energy difference between the two levels.

Similarly, an electron may move from a higher to a lower energy level, releasing energy that is equal to the energy difference between the higher and the lower level. This is known as emission.

Hence, if the electron is moving from a lower energy level to a higher energy level, an absorption has taken place, e.g n = 5 to n = 6

When an electron moves from a higher energy level to a lower energy level, an emission has taken place e.g n = 9 to n = 6
