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)

How does the type of medium affect a sound wave? Give an Example
ivanzaharov [21]

Answer:

Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly.Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.

A student heats a sample of Copper (II) sulfate in a crucible and records the data shown in the table. What is the complete form
liberstina [14]

Explanation:

Copper (II) sulfate is usually present as a hydrous state, which is of the form CuSO4 * nH2O, where n is a whole number.

Mass of sample (CuSO4 * nH2O)

= 152.00g - 128.10g = 23.90g.

Mass of water loss during heating

= 152.00g - 147.60g = 4.40g.

Molar mass of H2O = 18g/mol

Moles of H2O in sample

= 4.40g / (18g/mol) = 0.244mol.

Mass of anhydrous sample (CuSO4)

= 23.90g - 4.40g = 19.50g

Molar mass of CuSO4 = 159.61g/mol

Moles of CuSO4 in sample

= 19.50g / (159.61g/mol) = 0.122mol.

Since mole ratio of CuSO4 to H2O

= 0.122mol : 0.244mol = 1:2, n = 2.

Hence we have CuSO4 * 2H2O.
