2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s) T

brilliants [131]

Answer:

ΔHrxn = [(1) -1675.5 ( kJ/mole) + (2) 0 ( kJ/mole)] - [(1) -824.3 ( kJ/mole) + (2) 0 ( kJ/mole)]

Explanation:

ΔHrxn = 2ΔHf (Al₂O₃) - ΔHf (Fe₂O₃)

Remember that for pure elements in their standard state of temperature and pressure by definition their standard heats of formation are zero.

ΔHrxn = 2(-1675.7) - (-824.3) kJ/mol

ΔHrxn = 2527 kJ/mol

Why is a saturated NaCl solution an example of an equilibrium system? A. Because of the reversible nature of solidifying and mel

nataly862011 [7]

Answer:

Option B, Because of the reversible nature of crystallizing and dissolving

Explanation:

Solution containing the maximum amount of solute that can be dissolved in the given solvent at the particular temperature is called saturated solution.

Reversible reaction is the reaction which can go in reverse and forward direction both on varying reaction condition.

In the saturated NaCl solution, on lowering temperature, The the dissolved NaCl molecules may crystallize. Likewise on increasing temperature, the crystallized crystals may dissolved. As the reaction moves in both the direction, therefore its considered to be equilibrium system.

Therefore, amog given, option B is correct.

Because of the reversible nature of crystallizing and dissolving

Tatiana [17]

When Carboxylic Acid is treated with Alcohols in the presence of acid as a catalyst it produces corresponding Esters. This reaction is called as Esterification.
Also, this reaction is a reversible reaction and the ester formed can also hydrolyze to produce Carboxylic acid and Alcohol. This reverse reaction is called as transesterification.
The formation of Ethyl Acetate from Acetic Acid and Ethanol in the presence of acid is shown below,
