Determine the name and formula of a hydrate with the following composition; 32.30%

Chemistry
1 answer:
Maslowich2 years ago
7 0

1. The formula of the hydrate is FePO₄•4H₂O

2. The name of the hydrate is Iron(iii) phosphate tetrahydrate.

1. Determination of the formula of the hydrate

  • H₂O = 32.3%
  • FePO₄ = 67.7%
  • Formula =?

The formula of the hydrate can be obtained as follow:

Divide by their molar mass

H₂O = 32.3 / 18 = 1.794

FePO₄ = 67.7 / 151 = 0.448

Divide by the smallest

H₂O = 1.794 / 0.448 = 4

FePO₄ = 0.448 / 0.448 = 1

Therefore, the formula of the hydrate is FePO₄•4H₂O

The name of the hydrate is Iron(iii) phosphate tetrahydrate

One part nitrogen gas combines with one part oxygen gas to form how many part(s) dinitrogen monoxide (nitric oxide)?
____ [38]

Answer : The one part nitrogen gas combines with one part oxygen gas to form one part of dinitrogen monoxide.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When nitrogen gas combines with oxygen gas then it react to give dinitrogen monoxide or nitrous oxide.

The balance chemical reaction will be:

2N_2(g)+O_2(g)\rightarrow 2N_2O(g)

By the stoichiometry we can say that, 2 parts of nitrogen gas combines with 1 part of oxygen gas to give 2 parts of dinitrogen monoxide or nitrous oxide.

First we have to determine the limiting reagent.

From the reaction we conclude that,

As, 2 moles of nitrogen gas combine with 1 mole of oxygen gas

So, 1 moles of nitrogen gas combine with 0.5 mole of oxygen gas

It means that, oxygen gas is an excess reagent because the given moles are greater than the required moles and nitrogen gas is a limiting reagent and it limits the formation of product.

Now we have to determine the moles of dinitrogen monoxide.

As, 2 moles of nitrogen gas combine to give 2 mole of dinitrogen monoxide

So, 1 mole of nitrogen gas combine to give 1 mole of dinitrogen monoxide

Thus, the one part nitrogen gas combines with one part oxygen gas to form one part of dinitrogen monoxide.

Steve traveled the first 7 hours of his
const2013 [10]

Answer:

64

Explanation:

Distance traveled in 2 hours = 2 * 40 = 80 m

Distance traveled in 3 hours = 3 * 80 = 240m

Total distance covered = 240 + 80 = 320m

Total time = 2 + 3 =5 h

Hence avg speed = total distance covered / total time taken

= 320/5 = 64mph
