In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe(s) + 2 NiO(OH)(s)
AveGali [126]

Ans: Moles of Fe(OH)2 produced is 5.35 moles.

Given reaction:

Fe(s) + 2NiO(OH) (s) + 2H2O(l) → Fe(OH)2(s) + 2Ni(OH)2(aq)

Based on the reaction stoichiometry:

1 mole of Fe reacts with 2 moles of NiO(OH) to produce 1 mole of Fe(OH)2

It is given that there are:

5.35 moles of Fe

7.65 moles of NiO(OH)

Here the limiting reagent is Fe

Therefore, number of moles of Fe(OH)2 produced is 5.35 moles.

How do i balance the first chemical reaction above?? plz plz help
soldier1979 [14.2K]

Answer:

2K +F₂→ 2KF

Explanation:

When we balance an equation, we are trying to ensure that the number of atoms of each element is the same on both sides of the arrow.

On the left side of the arrow, there is 1 K atom and 2 F atoms. On the right, there is 1 K and 1 F atom.

Since the number of K atoms is currently balanced, balance the number of F atoms.

K +F₂→ 2KF

Now, that the number of F atoms is balanced on both sides, check if the number of K atoms are balanced.

<u>Left</u>

K atoms: 1

F atoms: 2

<u>Right</u>

K atoms: 2

F atoms: 2

The number of K atoms is not balanced.

2K +F₂→ 2KF

<u>Left</u>

K atoms: 2

F atoms: 2

<u>Right</u>

K atoms: 2

F atoms: 2

The equation is now balanced.

For a species with a diploid number of 26, indicate how many chromosomes will be present in the somatic nuclei of individuals th
Sedbober [7]

Answer:

Haploid - 13

Triploid - 39

Tetraploid - 52

Trisomic - 27

Monosomic - 25

Explanation:

A haploid organism has half the chromosome number of a diploid version, hence 26/2 = 13

A triploid organism has 3 sets of a haploid chromosomes, hence 13 x 3 = 39

A tetraploid is double of a diploid, 26 x 2 = 52

Trisomic organisms have one extra chromosome in addition to the normal diploid. Hence 26 + 1 = 27

Monosomic organism has one less chromosome than the normal diploid. Hence 26 - 1 = 25
