Using the thermodynamic information in the ALEKS Data tab, calculate the standard reaction entropy of the following chemical rea
Lapatulllka [165]

Answer:

-122 J/K

Explanation:

Let's consider the following balanced reaction.

N₂(g) + 2 O₂(g) ⇒ 2 NO₂(g)

We can calculate the standard reaction entropy (ΔS°) using the following expression.

ΔS° = Σ ηp × Sf°p - Σ ηr × Sf°r

where,

  • η: stoichiometric coefficients of products and reactants
  • Sf°r: entropies of formation of products and reactants

ΔS° = 2 mol × 240.06 J/K.mol - 1 mol × 191.61 J/K.mol - 2 mol × 205.14 J/K.mol

ΔS° = -121.77 J/K ≈ -122 J/K

Which of the following is not an indication of a chemical change? A.fracture formation. B.energy transfer. C.precipitate formati
julsineya [31]

In chemistry, there are two types of change, they are chemical and physical changes. A chemical change is one in which new substance are formed and it is always irreversible while a physical change is one in which no new substance is formed and it is always reversible. There are many factors that can indicate that a chemical change has taken place, these include: energy transfer, formation of precipitation, gas production, etc. Fracture formation does not indicate chemical change. In fracture formation nothing changes, so it is a form of physical change.

WHAT IS THE MOLAR MASS FOR AMMONIUM SULFIDE?<br> A. 59.1g/mol<br> B.82.2g/mol<br> C.50.1g/mol
Jobisdone [24]

Answer:

68g/mol

Explanation:

The formula of ammonium sulfide is:

 Ammonium sulfide  = (NH₄)₂S

 The molar mass of a compound is the mass in gram of one mole of the substance. In a compound, it is expressed gram formula mass or gram-molecular weight.

 It is determined by the addition of the component atomic masses and then expressed in grams;

     Atomic mass of N = 14, H  = 1 and S = 32

 (NH₄)₂S  = 2[14 + 4(1)] + 32  = 36 + 32  = 68g/mol

How many grams of potassium benzoate trihydrate, KC H302 - 3H20. are needed to prepare 1.5 L of a 0.120M solution of potassium b
Annette [7]

<u>Answer:</u> The mass of potassium benzoate is 8.40\times 10^{-4}g

<u>Explanation:</u>

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

We are given:

Molarity of solution = 0.120 M

Molar mass of potassium benzoate trihydrate = 214.26 g/mol

Volume of solution = 1.5 L

Putting values in above equation, we get:

0.120M=\frac{\text{Mass of potassium benzoate trihydrate}}{214.26\times 1.5}\\\\\text{Mass of potassium benzoate trihydrate}=\frac{0.120mol/L\times 1.5L}{214.26g/mol}=8.40\times 10^{-4}g

Hence, the mass of potassium benzoate is 8.40\times 10^{-4}g
