<h3><u>Answer;</u></h3>

Molar mass

<h3><u>Explanation</u>;</h3>
  • Stoichiometry involves the study of quantitative relationships between the amounts of reactants used and products formed by a chemical reaction.
  • A conversion factor is a ratio of coefficients found in a balanced reaction, which can be used to inter-convert the amount of products and reactants.
  • Molar ratios, or conversion factors, identify the number of moles of each reactant needed to form a certain number of moles of each product.

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.

For which of the following reactions are both reactants and products likely to be found when the reaction appears to be complete
Scorpion4ik [409]
The answer is
<span>HF + H2O <--> H3O(+) + F(-)
</span>
<span>HF + H2O gives  H3O(+) + F(-)
and </span>
 H3O(+) + F(-) gives <span>HF + H2O
it is a reciprocal reacation, so </span>
<span>reactions are both reactants and products </span>

Explain the current theory of what a quasar is and where quasars can be found.
Kay [80]

Answer:

Current understanding

It is now known that quasars are distant but extremely luminous objects, so any light which reaches the Earth is redshifted due to the metric expansion of space. ... Light and other radiation cannot escape from within the event horizon of a black hole.
