Answer:

Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)

Explanation:

Let's consider the molecular equation that occurs when aqueous BaCl₂ and aqueous (NH₄)₂SO₄ are mixed in solution to form aqueous NH₄Cl and solid BaSO₄. This is a double displacement reaction.

BaCl₂(aq) + (NH₄)₂SO₄(aq) ⇒ 2 NH₄Cl(aq) + BaSO₄(s)

The complete ionic equation includes all the ions and insoluble species.

Ba²⁺(aq) + 2 Cl⁻(aq) + 2 NH₄⁺(aq) + SO₄²⁻(aq) ⇒ 2 NH₄⁺(aq) + 2 Cl⁻(aq) + BaSO₄(s)

If 5.0 of al react with 9.0 g of O2, how many grams of Al2O3 (101.56 g/mol) can be formed
Law Incorporation [45]
<h3>Answer:</h3>

9.394 g of Al₂O₃

<h3>Explanation:</h3>

The reaction between Aluminium and Oxygen is given by the balanced equation;

4Al(s) + 3O₂(g) → 2Al₂O₃(s)

We are given;

  • Mass of Aluminium as 5.0 g
  • Mass of Oxygen as 9.0 g

We are required to determine the mass of Al₂O₃ formed.

We are going to use the following simple steps;

<h3>Step 1: Calculate the number of moles of Aluminium and Oxygen </h3>

Moles = Mass ÷ Molar mass

Moles of Al;

Molar mass of Al = 26.98 g/mol

Moles of Al = 5.0 g ÷ 26.98 g/mol

                   = 0.185 moles

Moles of Oxygen gas

Molar mass of O₂ = 32.0 g/mol

Moles O₂ = 9.0 g ÷ 32.0 g/mol

               = 0.28125 moles

  • From the equation, four moles of Aluminium reacts with three moles of oxygen gas.
  • Therefore, Aluminium is the rate limiting reagent while oxygen gas is in excess.
<h3>Step 2: Calculate the number of moles of Al₂O₃ formed </h3>

4 moles of Al reacts to produce 2 moles of Al₂O₃

Thus, the mole ratio of Al to Al₂O₃ is 2 : 1

Thus, moles of Al₂O₃ = Moles of Al ÷ 2

                                   = 0.185 moles ÷ 2

                                   = 0.0925 moles

<h3>Step 3: Calculate the mass of Al₂O₃ formed</h3>

Mass = Moles × Molar mass

Molar mass of Al₂O₃ is 101.56 g/mol

         = 0.0925 moles ×101.56 g/mol

         = 9.394 g

Therefore, the mass of Al₂O₃  formed is 9.394 g

An aqueous solution of nitric acid is standardized by titration with a 0.110 M solution of calcium hydroxide. If 21.1 mL of base
Mumz [18]

Answer:

\large \boxed{\text{0.195 mol/L}}

Explanation:

(a) Balanced equation

2HNO₃ + Ca(OH)₂ ⟶ Ca(NO₃)₂ + 2H₂O  

(b) Moles of Ca(OH)₂

\text{Moles of Ca(OH)}_{2} = \text{21.1 mL Ca(OH)}_{2} \times \dfrac{\text{0.110 mmol Ca(OH)}_{2}}{\text{1 mL Ca(OH)}_{2}}\\= \text{2.321 mmol Ca(OH)}_{2}

(c) Moles of HNO₃

The molar ratio is 2 mol HNO₃:1 mol Ca(OH)₂

\text{Moles of HNO}_{3} = \text{2.321 mmol Ca(OH)}_{2} \times\dfrac{\text{2 mmol HNO}_{3}}{\text{1 mmol Ca(OH)}_{2}}= \text{4.642 mmol HNO}_{3}

(d) Molar concentration of HNO₃

c = \dfrac{\text{moles of solute}}{\text{litres of solution}}\\\\c = \dfrac{n}{V}\\\\c= \dfrac{\text{4.642 mmol}}{\text{23.8 mL}} = \text{0.195 mol$\cdot$L$^{-1}$}\\\\\text{The molar concentration of the Ca(OH)$_{2}$ is $\large \boxed{\textbf{0.195 mol/L}}$}

You have four beakers. Put in order from least heat energy to most heat energy.
Elenna [48]
Hi! So, to solve this problem you first have to put the information in a ratio of volume to temperature. After that, i used a calculator to divide. The resulting number is the amount of heat energy in the beaker, but simplified.

You end up with Beaker B, A, C, D (from the least to greatest amount of heat energy). I hope this helps!! :))
