The extraction of aluminum metal from the aluminum hydroxide in bauxite ore by the Hall-Héroult process is one of the most remar

kable success stories of late 19th century practical chemistry, turning aluminum from a rare and precious metal into the cheap commodity it is today. In the first step, aluminum hydroxide reacts to form alumina and water: 2AlOH3(s)→Al2O3(s)+3H2O(g) In the second step, alumina and carbon react to form aluminum and carbon dioxide: 2Al2O3(s)+3C(s)→4Al(s)+3CO2(g) Write the net chemical equation for the production of aluminum from aluminum hydroxide and carbon. Be sure your equation is balanced.

<u>Answer:</u> The net chemical equation for the  production of aluminium from aluminium hydroxide and carbon is 2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)

<u>Explanation:</u>

The given intermediate reactions are:

<u>Step 1:</u>  2Al(OH)_3(s)\rightarrow Al_2O_3(s)+3H_2O(g)

<u>Step 2:</u>  2Al_2O_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)

By combining these two above equations, we will get the net chemical equation for the production of aluminium from aluminium hydroxide and carbon.

The net chemical equation follows:

2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)

Hence, the net chemical equation for the  production of aluminium from aluminium hydroxide and carbon is 2Sl(OH)_3(s)+3C(s)\rightarrow 4Al(s)+3CO_2(g)+3H_2O(g)

A sample of gas in a balloon has an initial temperature of 20. ∘C and a volume of 1.92×103 L . If the temperature changes to 68
morpeh [17]

Answer:

\boxed{2.23 \times 10^{3} \text{ L}}

Explanation:

The pressure is constant, so we can use Charles' Law.

\dfrac{ V_{1} }{T_{1}} = \dfrac{ V_{2} }{T_{2}}

Data:

V₁ = 1.92 × 10³ L; T₁ = 20 °C  

V₂ = ?;                 T₂ = 68 °C

Calculations:

(a) Convert temperatures to kelvins

T₁ = (20 + 273.15) K = 293.15 K

T₂ = (68 + 273.15) K = 341.15 K

(b) Calculate the volume

\dfrac{ 1.92 \times 10^{3}}{293.15} = \dfrac{ V_{2}}{341.15}\\\\6.550 = \dfrac{ V_{2}}{341.15}\\\\V_{2} = 6.550 \times 341.15 = 2.23 \times 10^{3} \text{ L}

The new volume of the gas is \boxed{2.23 \times 10^{3} \text{ L}}.
