How many grams of aluminum chloride can be produced from 7.32g of ammonium perchlorate?
Alla [95]

Answer:

2.77g of AlCl_{3} can be produced.

Explanation:

Use stoichiometry.

Balanced equation: 3Al + 3NH_{4} ClO_{4} ⇒ Al_{2} O_{3} + AlCl_{3} +3NO + 6H_{2} O

NH_{4} ClO_{4}  :  AlCl_{3}

      3        :     1                        **n=\frac{m}{M}

 0.0623**   :    x                        n=\frac{7.32}{117.49}   = 0.0623

      3x=0.0623\\x=0.020767

n=\frac{m}{M}    

m=nM

m= (0.020767)(133.34)

m= 2.77g

A chemist measures the solubility of lead(ii) bromide in water to be 2. 96 g/l. calculate the ksp value for the solid. the ksp v
Julli [10]

The solubility product, ksp of PbBr₂ is 2.102 × 10⁻⁶

<h3>What is solubility?</h3>

The solubility of a solute is defined as the maximum amount of that solute that can be dissolved in a known quantity of solvent at a given temperature.

<h3>What is a solubility product? </h3>

Some salts are sparingly soluble in a solvent. For them, we calculate the solubility product.

It is an equilibrium constant that defines the relationship between a solid and its respective ions in an aqueous solution in equilibrium.

The greater the solubility product, the greater the solubility and vice versa.

Here, the solubility of PbBr₂ = 2.96 g/l

Molar solubility of  PbBr₂ = \frac{2.96}{molar mass of PbBr_2} = 2.96/367 = 8.07 × 10⁻³

At equilibrium,

PbBr_2\rightarrow Pb^{2+} + 2Br^-

1 mole of PbBr2 dissociates into 1 mole of Pb²⁺ ions and 2 moles of Br⁻

Let the molar concentration of Pb²⁺ be x, then the molar concentration of Br⁻ is 2x

Ksp = x.(2x)²

       = 4x³

Substitute, x = 8.07 × 10⁻³

Ksp = 4 (8.07 × 10⁻³)³

      = 2.102 × 10⁻⁶

Thus, The ksp of PbBr₂ is 2.102 × 10⁻⁶

Oxidation of a 24-carbon fatty acid would require _____ rounds of beta-oxidation and ______ rounds of the krebs cycle.
Anvisha [2.4K]

Oxidation of a 24-carbon fatty acid would require ELEVEN (11) rounds of beta-oxidation and TWELVE (12) rounds of the Krebs cycle. It is part of cellular respiration.

<h3>The Krebs cycle and cellular respiration</h3>

Cellular respiration is a group of chemical reactions by which aerobic cells can produce ATP by using energy from foods.

Cellular respiration has three parts: glycolysis, the Krebs cycle (also called the acid citric cycle) and oxidative phosphorylation.

During the Krebs cycle, hydrogen atoms or electrons pass through a series of hydrogen/electron carriers.
