In completing a Fischer Esterification experiment using acetic acid and unknown alcohol catalyzed by sulfuric acid a student sta
masha68 [24]

Answer:

The equilibrium law

Explanation:

According to the equilibrium law , when $\text{concentration}$ of any of the  reactants or the products in the reaction at an equilibrium state,  is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of

Acetic acid (in excess) + $\text{alcohol}$ ⇄  $\text{ester}$ + water

$\text{Fischer esterification}$ is a reaction which involves the equilibrium. So to force the reaction towards the side of $\text{ester}$, one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.

A container of N2O3(g) has a pressure of 0.265 atm. When the absolute temperature of the N2O3(g) is tripled, the gas completely
Rzqust [24]

Answer:

1.59 atm

Explanation:

The reaction is:

N_{2}O_{3}(g) - - -> NO_{2}(g)+NO(g)

The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.

So after the reaction the total pressure is:

P_{total}=P_{NO_{2}}+P_{NO}

we don't include N_{2}O_{3} because it decomposed completely.

Assuming  ideal gases

PV=nRT

P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.

so moles of N_{2}O_{3} is:

n_{N_{2}O_{3}}=\frac{P_{1}V}{RT_{1}}

from the  reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of N_{2}O_{3}.

n_{NO_{2}}=\frac{P_{1}V}{RT_{1}}

n_{NO}=\frac{P_{1}V}{RT_{1}}

The partial pressure of each gas is:

P_{NO_{2}}=\frac{n_{NO_{2}*R*T_{2}}}{V}

P_{NO}=\frac{n_{NO}*R*T_{2}}{V}

so total pressure is:

P_{total}=(n_{NO_{2}}+n_{NO})*\frac{R*T_{2}}{V}

replacing the moles we get:

P_{total}=(2*\frac{P_{1}V}{RT_{1}})*\frac{R*T_{2}}{V}

We know that T2=3*T1

replacing this value in the equation we get:

P_{total}=2*\frac{P_{1}V}{RT_{1}}*\frac{R*3T_{1}}{V}

P_{total}=6*P_{1} = 6*0.265 atm = 1.59 atm

Calculate the number of atoms in 3.21 mole of Mg?
Mars2501 [29]

Answer:

<h2>1.93 × 10²⁴ atoms</h2>

Explanation:

The number of atoms in a substance can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 3.21 × 6.02 × 10²³

We have the final answer as

<h3>1.93 × 10²⁴ atoms</h3>

Hope this helps you
