Answer: 7.36 moles of [tex]CaBr_2[/tex] will be produced.

Explanation:

We are given:

Moles of NaBr = 14.72 moles

The given chemical equation follows:

[tex]2NaBr+Ca(OH)_2\rightarrow CaBr_2+2NaOH[/tex]

By the stoichiometry of the reaction:

2 moles of NaBr produces 1 mole of calcium bromide

So, 14.72 moles of NaBr will produce = [tex]\frac{1}{2}\times 14.72=7.36mol[/tex] of calcium bromide

Hence, 7.36 moles of [tex]CaBr_2[/tex] will be produced.

Answer:

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

Explanation:

La ley de conservación de la materia establece que, dado que no se puede crear ni destruir ningún átomo en una reacción química, el número de átomos que están presentes en los reactivos debe ser igual al número de átomos presentes en los productos.

Luego, debes equilibrar la ecuación química. Para eso, primero debe mirar los subíndices al lado de cada átomo para encontrar el número de átomos en la ecuación. Si el mismo átomo aparece en más de una molécula, debes sumar sus cantidades.

Los coeficientes ubicados frente a cada molécula indican la cantidad de cada molécula para la reacción. Este coeficiente puede modificarse para equilibrar la ecuación, del mismo modo que nunca debe alterar los subíndices.

Al multiplicar el coeficiente mencionado por el subíndice, obtienes la cantidad de cada elemento presente en la reacción.

En este caso la reacción química es:

Fe₂O₃ + 3 H₂O ⇒ ____ Fe(OH)₃

Entonces, teniendo en cuenta todo lo anterior, se puede determinar la cantidad de elementos en cada lado de la ecuación:

Se puede observar que la reacción química no esta balanceada porque se tiene diferentes cantidades de cada elemento a cada lado de la reacción. Para equilibrarla, se comienza balanceando el hierro. Para eso, el coeficiente estequiométrico debe ser dos:

Fe₂O₃ + 3 H₂O ⇒ 2 Fe(OH)₃

Entonces:

Ahora, a cada lado de la reacción se tiene la misma cantidad de cada elemento, por lo que la reacción esta balanceada.

Para que se cumpla el balanceo en la reacción química, en el espacio se debe asignar 2 como coeficiente estequiométrico.

Answer:

143.9 mL is the new volume for the gas.

Explanation:

Let's apply one of the gases law to solve this problem:

Boyle's law states that the product of pressure and volume remains constant when the T° is not modified.

P₁ . V₁ = P₂ . V₂

Be careful because we have T° in mmHg. We need to convert to atm:

750.12 mmHg . 1 atm / 760 mmHg = 0.987 atm

We replace data:

150 mL . 0.947 atm = 0.987 atm . V₂

V₂ = (150 mL . 0.947 atm) / 0.987 atm

V₂ = 143.9 mL

This term P . V comes from the Ideal Gases Law

P . V = n . R . T

Answer:

may or may not be equal to the number of moles of the products.

Explanation:

A chemical reaction involves the interaction between reactants to yield products. The number of moles of reactants and products in the system depends on the stoichiometry of the reaction.

The balanced reaction equation shows us the number of moles of reactants and products involved in the reaction.

Hence, in the balanced chemical reaction equation; the number of moles of reactants may or may not be equal to the number of moles of the products.

The Mass of 22.4 L or 1 mole of H2 gas is 2.02 grams

The molar volume of a gas at STP is equal to 22.4 L

This means that 1 mole of the gas occupies a volume of 22.4 L

Thus, 22.4 L of H2 gas equals one mole of H2 gas.

Mass of 1 mole of H2 gas = 2.02 grams

Answer:

14 g of N2

Explanation:

If we look at the options, we will notice that the correct answer needs to be a gas that has about half of the molecular mass of the gas.

If we consider nitrogen gas whose molecular mass is 28g/mol, half of the molecular mass is 14 g.

So;

28g of N2 contains 6.02 × 10^23 molecules of N2

14g of N2 contains 14 × 6.02 × 10^23 /28

= 3.0 x 10^23

Answer:

The value for the equilibrium constant for the reaction [tex]2SO2(g)+O2(g) <=> 2SO3(g) Kc=4.0*10^24\\[/tex] at 298K .

What would be the value for the equilibrium constant for the following reaction at the same temperature?

[tex]2SO3(g) <=> 2SO2(g)+O2(g)[/tex]

Explanation:

The Kc value for the reverse reaction of the first reaction that is:

[tex]2SO2(g)+O2(g) <=> 2SO3(g) Kc=4.0*10^{24}\\[/tex]

[tex]Kc=\frac{SO3^{2} }{SO2^{2}.O2 }[/tex]

For the reverse reaction,

[tex]2SO3(g) <=> 2SO2(g)+O2(g)[/tex]

[tex]Kc=\frac{SO2^{2}O2 }{SO3^{2}. }[/tex]

So, it is the inverse of the first Kc value.

Hence, the new Kc value is:

[tex]Kc=\frac{1}{4.0*10^{24} } \\ =2.5*10^{-25}[/tex]

Answer is :

Kc=2.5*10^-25.
