How many grams of aluminum can be recovered from a 34.5 g sample of al2o3?

Chemistry
1 answer:
AnnyKZ [126]2 years ago
6 0

18.26 g of Al can be recovered.

<h3>Calculation:</h3>

The equation that follows is:

2Al₂O₃ → 2Al + 3O₂

The atomic mass of Al = 27 g

The molecular mass of Al₂O₃ = 102 g

From the stoichiometric equation, 102g of Al₂O₃ yields 54 g of Al

Therefore,

34.5 g of Al₂O₃ will give = \frac{54 (34.5)}{102}

                                        = 18.26 g

What is the idea behid boyles law​
zavuch27 [327]

Answer:

Explanation:

For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

What mass of potassium chloride, KCl, is produced when 12.6 g of oxygen, 02, is produced?
blagie [28]

Mass of KCl= 19.57 g

<h3>Further explanation</h3>

Given

12.6 g of Oxygen

Required

mass of KCl

Solution

Reaction

2KClO3 ⇒ 2KCl + 3O2

mol O2 :

= mass : MW

= 12.6 : 32 g/mol

= 0.39375

From the equation, mol KCl :

= 2/3 x mol O2

= 2/3 x 0.39375

=0.2625

Mass KCl :

= mol x MW

= 0.2625 x 74,5513 g/mol

= 19.57 g

How is a weak acid DIFFERENT from a dilute acid?
telo118 [61]
In a dilute acid solution most if not all of the molecules will split into ions.
For example HCl is a strong acid and 100% of the molecules will split into
H+ & Cl-

in a weak acid solution only a portion of the molecules will turn into ions because the ionization percentage isn't as large. Which will essentially leave a high percentage of un-reacted molecules
