A chemical engineer must calculate the maximum safe operating temperature of a high-pressure gas reaction vessel. The vessel is

Anuta_ua [19.1K]

The maximum safe operating temperature for this reaction is equal to 895°C.

<u>Given the following data:</u>

Width of cylinder = 22 cm.

Height, h = 26.4 cm.

Maximum safe pressure = 6.30mpa.

Mass = 0.537 kg.

<u>Scientific data:</u>

Ideal gas constant, R = 8.314 L-kPa/Kmol.

Molar mass of of dinitrogen monoxide ( $N_2F_2$ ) gas = 66 g/mol.

Radius, r = $\frac{width}{2} =\frac{22}{2} =11\;cm$

<h3>How to calculate the maximum safe operating temperature.</h3>

First of all, we would determine the volume of the stainless-steel cylinder by using this formula:

$V=\pi r^2 h\\\\V = 3.142 \times 11^2 \times 26.4\\\\$

Volume, V = 10,036.81 $cm^3$ .

In liters, we have:

Volume, V = 10.04 Liters.

Next, we would determine the number of moles of dinitrogen monoxide ( $N_2F_2$ ) gas:

$Number \;of \;moles = \frac {mass}{molar\;mass}\\\\Number \;of \;moles = \frac {537}{66}$

Number of moles = 8.136 moles.

Now, we can solve for the maximum safe operating temperature by applying the ideal gas equation:

$PV=nRT\\\\T=\frac{PV}{nR} \\\\T=\frac{6.30 \times 10^3 \times 10.04}{8.136 \times 8.314}\\\\T=\frac{60541.2}{67.6427}$

T = 895.02 ≈ 895°C.

Write the balanced COMPLETE ionic equation for the reaction when aqueous NiCl₂ and aqueous Na₂S are mixed in solution to form so

Reptile [31]

Answer:

Explanation:

The chemical reaction of the well-balanced equation is as follows:

$\mathbf{2NiCl_{2(aq)}+2Na_2S_{(aq)} \to 4NaCl_{(aq)}+2NiS_{s}}$

The aforementioned reaction's ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+4Cl^-_{(aq)}+ 4Na^+_{(aq)}+2S^{2-}_{(aq)} \to 4Na^+_{(aq)}+4Cl^-_{(aq)}+2NiS_{(s)}}$

From above; Na⁺ and Cl⁻ appear on both sides;

Hence, the net ionic equation is:

$\mathbf{2Ni^{2+}_{(aq)}+2S^{2-}_{(aq)} \to 2NiS_{(s)}}$

Automobile catalytic converters use a platinum catalyst to reduce air pollution by changing emissions such as carbon monoxide, C

julia-pushkina [17]

Answer: 448 g of $O_2$ will be required to completely react with 784g moles of CO(g) during this reaction.

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} CO=\frac{784g}{28g/mol}=28moles$

The balanced chemical equation is:

$2CO(g)+O_2(g)\rightarrow 2CO_2(g)$

According to stoichiometry :

2 moles of $CO$ require = 1 mole of $O_2$

Thus 28 moles of $CO$ will require= $\frac{1}{2}\times 28=14moles$ of $O_2$

Mass of $O_2=moles\times {\text {Molar mass}}=14moles\times 32g/mol=448g$

Thus 448g of $O_2$ will be required to completely react with 784g moles of CO(g) during this reaction.
