<h3><u>Answer</u>;</h3>

B) Al2O3

<h3><u>Explanation;</u></h3>

Aluminium reacts with oxygen to form aluminium oxide.

The chemical reaction for the reaction between Aluminium and Oxygen is;

4Al+ 3O₂→ 2Al₂O₃

Therefore;

Compound X is Aluminium oxide (Al₂O₃)

<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

When aluminium metal reacts with air, it produces an oxide named as aluminium oxide. The chemical formula for this compound is $Al_2O_3$

The balanced chemical equation for the above reaction follows:

$4Al(s)+3O_2(g)\rightarrow 2Al_2O_3(s)$

By Stoichiometry of the reaction:

4 moles of aluminium metal reacts with 3 moles of oxygen to produce 2 moles of aluminium oxide.

This reaction is a type of synthesis reaction because substances are reacting in their elemental state to produce one compound.

Hence, the correct answer is Option B.

The standard free energy of activation of a reaction A is 81.9 kJ mol–1 (19.6 kcal mol–1) at 298 K. Reaction B is one million ti

klasskru [66]

Answer:

54.9 kJ/mol

Explanation:

The relation between the activation energy (Ea) and the rate constant (k) is given by the Arrhenius equation.

$k=A.e^{-Ea/RT}$

where,

A is a collision factor

R is the ideal gas constant

T is the absolute temperature

Reaction B is one million times faster than reaction A at the same temperature. So $k_{B}=10^{6} k_{A}$ .

Then,

$k_{B}=10^{6} k_{A}\\A.e^{-Ea_{B}/RT}=10^{6}A.e^{-Ea_{A}/RT}\\e^{-Ea_{B}/RT}=10^{6}e^{-Ea_{A}/RT}\\ln(e^{-Ea_{B}/RT})=ln(10^{6}e^{-Ea_{A}/RT})\\\frac{-Ea_{B}}{RT} =ln10^{6} -\frac{Ea_{A}}{RT} \\Ea_{B}=(ln10^{6} -\frac{Ea_{A}}{RT}).(-RT)=(ln10^{6}-\frac{89.1kJ/mol}{(8.314\times 10^{-3} kJ/mol.K).298K} ).(-8.314\times 10^{-3} \frac{kJ}{mol.K}.298K )=54.9kJ/mol$

What converts the sugar in grapes into alcohol?

kykrilka [37]

The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product).
